Which examination and professional level does this guide address?

This guide addresses the Royal College of Obstetricians and Gynaecologists MRCOG Part 2, a specialty membership examination assessing applied knowledge in clinical scenarios. The descriptive label 'MRCOG Part 2 Written Examination' refers to this same examination. Candidates must have passed Part 1. Part 2 alone does not award MRCOG membership or constitute a general medical licensing qualification; successful completion of all three parts is required for membership.

MRCOG exam overview

How many papers and questions are there, and how long do they last?

There are two computer-based papers. Each lasts 180 minutes and contains 50 single best answer questions and 50 extended matching questions: 100 questions per paper and 200 across both papers. Each paper contributes 50% of the examination result.

MRCOG Part 2: exam format

Which question styles and marking weights apply?

The actual examination uses single best answer questions, or SBAs, and extended matching questions, or EMQs. SBA marks contribute 40% and EMQ marks 60%. These are question-format weights, not clinical-domain percentages. The 20 questions in this guide are independent four-option SBA learning drills and do not reproduce the EMQ component.

MRCOG Part 2: exam format

Is the examination adaptive, and is there a fixed passing score?

RCOG describes two computer-based papers; its format page does not specify adaptive delivery. A combined pass mark is determined for each examination, so a universal fixed passing percentage should not be assumed. The page does not specify a separate pass requirement for each paper.

Which syllabus version applies to this guide?

The RCOG-linked syllabus is MRCOG Syllabus and Knowledge Requirements for Core Curriculum, April 2024, version 1.0, with a version-control entry dated 2 April 2024. No separate Part 2 examination effective date is stated. The syllabus landing page retains Curriculum 2019 wording while linking to the April 2024 document.

How closely does the guide follow official domain weighting?

The official syllabus identifies 15 knowledge areas without numerical knowledge-area weights. Concept selection illustrates clinical decisions within those areas; it does not establish their relative examination importance or provide exhaustive coverage. Questions and flashcards cover every area, with additional practice in maternal medicine, labour, postpartum problems, gynaecological problems and early pregnancy care. This distribution is educational rather than an official weighting.

Which jurisdiction and recent clinical reference changes are reflected?

Professional and clinical discussions primarily use UK GMC, RCOG and NHS sources, supplemented by WHO and Cochrane. UK consent legislation differs between the four countries; the capacity example explicitly uses the Mental Capacity Act framework for England and Wales. Shoulder dystocia content uses the RCOG third edition published on 27 August 2026. Postmenopausal ovarian cyst content reflects the December 2025 guideline amendment.

60 key concepts: understand, apply and avoid the traps

Work through the questions by exam domain. Explain the answer in your own words, try the example, then check the common pitfall.

Clinical skillsnot stated

1.Which risks matter when discussing consent?

A useful consent discussion connects reasonable options, expected benefits, possible harms and the option of no intervention with the individual patient's priorities. Materiality depends on what this person would consider significant, rather than complication frequency alone. Ask about fertility, work, caring responsibilities and acceptable outcomes before recommending an option. A technically uncommon harm may dominate the decision when its consequences conflict with something the patient values highly.

Apply it

A singer considering surgery is particularly worried about any effect on her ability to perform. Explore that concern, explain relevant uncertainties and alternatives, and document how her priorities influenced the agreed plan.

Common pitfall: Reciting a standard complication list can miss the decisive issue. A signed form does not establish that the patient understood personally significant risks.

The seven principles of decision making and consent

2.How should capacity be assessed for a specific decision?

Presume capacity and provide practicable support, including accessible information, communication aids and treatment of reversible barriers. In England and Wales, a person lacks capacity for a particular decision at that time if an impairment or disturbance of mind or brain makes them unable to understand relevant information, retain it long enough to decide, use or weigh it, or communicate a decision by any means. Assess the causal connection and document which ability is impaired. A diagnosis, refusal or apparently unwise choice alone does not establish incapacity. Other UK jurisdictions have different legal frameworks.

Apply it

A patient with delirium can repeat that surgery may prevent serious harm but, despite support, cannot use or weigh how accepting or declining it affects her. Repetition demonstrates some recall, not necessarily capacity. Document the functional difficulty and its relationship to delirium; consider whether the decision can wait for recovery.

Common pitfall: Checking factual recall alone misses inability to use or weigh consequences. Communication difficulty also requires support rather than an automatic finding of incapacity.

The seven principles of decision making and consent · Making decisions: a guide for people who work in health and social care - GOV.UK

3.How can communication support improve a treatment decision?

Patients need information they can understand, time to consider it and support to express what matters to them. Explore language, sensory, literacy and emotional barriers rather than assuming that silence means agreement. Break complex choices into manageable parts and invite the patient to explain the options in their own words. Support should help the patient reach their own decision; it should not become pressure to accept the clinician's preferred treatment.

Apply it

A patient repeatedly nods during a complex fertility discussion but cannot describe the choices. Arrange appropriate language support, revisit the explanation in smaller sections and check understanding before seeking a treatment decision.

Common pitfall: Asking only whether someone understands often produces an uninformative yes. Agreement may reflect politeness, distress or a communication barrier rather than informed choice.

The seven principles of decision making and consent

4.When must an earlier consent decision be revisited?

Consent is an ongoing decision-making process. Revisit it when the proposed intervention, relevant information, patient's circumstances or expressed wishes change. Earlier agreement does not remove the need to listen to a later refusal or request to pause. Clarify the patient's current wishes, assess any capacity concern appropriately and explain the consequences of available choices. A decision that appears medically unwise can still be a valid exercise of autonomy by an informed adult with capacity.

Apply it

Immediately before an elective procedure, a patient says she no longer wants it after discussing alternatives with her partner. Pause the process, speak with her directly and establish her current informed decision without pressure.

Common pitfall: Treating a previously signed form as irrevocable permission confuses documentation with consent. The patient's current decision remains central throughout the care process.

Teaching and researchnot stated

5.How should absolute benefit, relative benefit and number needed to treat be interpreted together?

Calculate each group's event risk before comparing them. Absolute risk reduction is control risk minus intervention risk; relative risk is intervention risk divided by control risk. Relative risk reduction is one minus relative risk. For a reduction in an adverse outcome, NNT is one divided by the absolute reduction expressed as a proportion, rounded upward. State the outcome and follow-up period. Absolute benefit changes with baseline risk: halving a 20% risk prevents ten events per 100 people, whereas halving a 2% risk prevents one. Consider uncertainty, harms and clinical importance alongside these summaries.

Apply it

In a hypothetical one-year trial, complications occur in 48 of 400 controls and 32 of 400 treated participants. Risks are 12% and 8%; absolute reduction is four percentage points, relative reduction is 33.3% and NNT is 25. A separate absolute reduction of 0.03 gives NNT 34 after rounding upward.

Common pitfall: Percentage points and relative percentages differ. NNT describes an average comparative effect and cannot identify which individual will benefit.

Cochrane Handbook, Chapter 15: Interpreting results and drawing conclusions

6.How can a favourable trial result still be unreliable?

Appraise how participants entered the comparison before interpreting the effect size. Adequate randomisation and concealed allocation protect against selection bias; blinding can reduce differences in care and outcome assessment. Examine prespecified outcomes, missing data, exclusions after allocation and analysis by assigned group. Intention-to-treat analysis preserves the original comparison, although missing outcomes still require scrutiny. Then assess precision, harms and applicability. A small P value does not correct biased methods or establish that the benefit matters to the patient.

Apply it

A hypothetical trial allocates treatment by alternating admission dates, reports subjective pain without blinded assessment and excludes participants who stop treatment because of adverse effects. Predictable allocation permits selection bias, unblinded ratings risk biased measurement and exclusions can exaggerate benefit while hiding harm. A statistically significant result does not resolve these weaknesses.

Common pitfall: Calling a study a trial does not establish valid randomisation. A precise estimate can still be systematically biased.

7.Which teaching approach best supports an adult learning a practical emergency skill?

Start by identifying the learner's existing experience and the specific performance gap, then agree an observable objective relevant to clinical work. Demonstrate the skill, allow supervised practice and give timely feedback on observed actions. Invite reflection and repeat practice to check improvement. Adults benefit from understanding why learning matters and applying knowledge to a problem. Match assessment to the objective: factual recall alone cannot establish competent practical performance.

Apply it

A trainee can list shoulder dystocia manoeuvres but struggles to coordinate them in simulation. Agree an objective of recognising failure of an external manoeuvre and progressing promptly. Use a simulated case, observe actions, discuss the trainee's reasoning, give specific feedback and repeat the scenario to assess improvement.

Common pitfall: Repeating a lecture addresses information delivery but may leave a demonstrated performance gap unchanged. Feedback should describe behaviour and an achievable next step.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

8.What completes a clinical audit cycle?

Clinical audit compares observed care with explicit standards and uses the findings to improve practice. Define a measurable standard, collect appropriate data, identify gaps, implement a practical change and measure again. Re-audit establishes whether care improved rather than merely showing that an educational meeting occurred. Research asks questions intended to generate new knowledge; audit examines performance against a chosen standard. Both require appropriate governance, confidentiality and careful handling of patient information.

Apply it

An audit finds that surgical checks are incompletely recorded. The team redesigns the workflow and assigns clear responsibilities. A later sample measures completion using the same definitions to determine whether the intervention improved practice.

Common pitfall: Presenting baseline percentages alone does not close the cycle. Improvement requires an implemented change and subsequent measurement, with attention to data quality and patient confidentiality.

Core surgical skillsnot stated

9.How do the three WHO surgical checklist phases address different hazards?

Sign-in before anaesthesia confirms identity, procedure, site and consent, plus anaesthetic hazards such as allergy, airway difficulty and anticipated blood loss. Time-out before incision aligns the team through introductions, verbal confirmation and discussion of critical steps, duration, bleeding, equipment and imaging. Sign-out before leaving theatre confirms the procedure, final counts, specimen labels, equipment problems and recovery concerns. Read specimen labels aloud, including the patient's name. Each phase occurs while its particular hazards can still be addressed.

Apply it

Before complex pelvic surgery, time-out reveals anticipated major bleeding but inadequate vascular access. Address this before incision. At sign-out, resolve specimen and count discrepancies and communicate the postoperative plan before transfer.

Common pitfall: A completed form cannot replace active communication. Ward checks do not remove sign-in, and sign-out includes more than acknowledging that the operation has finished.

WHO Surgical Safety Checklist

10.How should tissue characteristics guide selection of grasping forceps?

Match the gripping surface to the tissue and intended task. Babcock forceps have broad, curved jaws suited to holding delicate structures such as bowel with less focal trauma. Rat-tooth forceps provide a firm grip on skin and dense tissue through interlocking teeth. A secure grip suitable for tough tissue may injure a delicate hollow organ. Instrument choice therefore requires recognition of jaw design and intended use, rather than selection by handle shape alone. See the [Egyptian Health Council instrument manual](https://lms.ehc.gov.eg/lms/mod/book/view.php?chapterid=2952&id=518).

Apply it

When delicate bowel needs gentle holding during pelvic surgery, select an appropriate Babcock rather than rat-tooth forceps intended for dense tissue. Apply only the force needed for the task.

Common pitfall: An instrument described as atraumatic does not make excessive compression harmless. Firm purchase and tissue preservation must both inform handling.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

11.How can laparoscopic electrosurgery injure tissue outside the intended target?

Direct coupling transfers current when an active electrode touches another instrument contacting tissue. Capacitive coupling can transfer energy between nearby conductors across insulation without direct contact. Insulation defects create another route for unintended injury. Keep the exposed active electrode visible, inspect insulation, use short activations and the lowest effective power, and establish intended tissue contact before activation. Consider bipolar equipment when appropriate. These precautions address burns that may occur outside the operative view. See the [Association for Perioperative Practice guidance](https://www.afpp.org.uk/wp-content/uploads/Standards-Collection-Laparoscopic-Surgery.pdf).

Apply it

An active laparoscopic electrode approaches a metal instrument touching bowel. Stop activation and separate the instruments before proceeding; a clear view of the target alone does not prevent current passing through the adjacent instrument.

Common pitfall: Intact-looking insulation does not exclude capacitive coupling. Failure to see a burn at the active tip does not establish that no unintended injury occurred elsewhere.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

12.When should antibiotic prophylaxis be checked in the surgical safety sequence?

The WHO checklist asks before incision whether indicated antibiotic prophylaxis has been given within the preceding 60 minutes. This check links antibiotic delivery to the period when operative contamination may occur. The checklist also permits a not-applicable response, so it does not establish that every procedure requires the same antibiotic. Determine indication and agent from the relevant surgical protocol, then use the time-out to confirm that the planned prophylaxis was actually delivered at the appropriate time.

Apply it

During time-out, prophylaxis is documented as prescribed but nobody can confirm administration. Check the administration record and resolve the omission before incision rather than treating the prescription itself as evidence that the patient received it.

Common pitfall: Prescribed and administered are different states. The checklist timing check does not supply an antibiotic choice or justify giving the same regimen for every operation.

WHO Surgical Safety Checklist

Postoperative carenot stated

13.Which postoperative leg symptoms suggest venous thrombosis?

A painful, swollen, hot or red leg after surgery raises concern for deep vein thrombosis. Surgery and reduced mobility create a clinically important context in which a new unilateral leg problem should not be dismissed as muscular discomfort. Arrange prompt medical assessment because a venous clot may embolise to the lungs. Distinguish these warning symptoms from the expected gradual improvement in general postoperative soreness, while recognising that symptoms alone do not establish the diagnosis.

Apply it

Five days after hysterectomy, a patient reports that one calf has become swollen and painful while the other is comfortable. Advise prompt assessment for possible venous thrombosis rather than waiting for a routine recovery appointment.

Common pitfall: Being able to walk does not exclude thrombosis. Mobilisation supports prevention but cannot be used to dismiss a new unilateral painful swelling after surgery.

Abdominal hysterectomy — recovering well

14.When do postoperative chest symptoms require immediate help?

New shortness of breath, chest pain or coughing up blood after surgery can indicate pulmonary embolism and requires immediate medical help. The postoperative setting increases the importance of these symptoms even when recovery had previously seemed uncomplicated. A preceding painful leg may support the concern, but its absence does not make chest symptoms safe to observe at home. Recognise the emergency pattern first; diagnostic confirmation and treatment then occur through an urgent clinical assessment.

Apply it

A patient recovering at home after abdominal hysterectomy suddenly develops breathlessness and chest pain. Direct her to immediate emergency care rather than suggesting that she wait to see whether rest or oral analgesia helps.

Common pitfall: Attributing sudden breathlessness to anxiety without assessment can miss a dangerous complication. Absence of leg symptoms does not reliably exclude a clot affecting the lungs.

Abdominal hysterectomy — recovering well

15.How does a changing recovery pattern signal postoperative infection?

Postoperative recovery should generally progress, so increasing pain, fever or a wound becoming red and painful warrants assessment for infection or another complication. Offensive vaginal discharge or heavy bleeding after hysterectomy also needs review. Interpret symptoms together and compare them with the patient's earlier trajectory. A new deterioration after initial improvement is more concerning than stable mild discomfort. Do not assume that every postoperative symptom is an expected consequence of tissue healing or normal recovery.

Apply it

A patient initially improves after hysterectomy but then develops fever, worsening lower abdominal pain and unpleasant-smelling discharge. Arrange medical review for a postoperative complication instead of extending routine reassurance about expected discomfort.

Common pitfall: A tidy external wound does not exclude an internal or urinary complication. Assess the whole symptom pattern rather than allowing one reassuring observation to dominate.

Abdominal hysterectomy — recovering well

16.Why should activity increase gradually after abdominal hysterectomy?

Gradual mobilisation supports circulation and functional recovery while allowing healing tissues and energy levels to recover. Begin with manageable walking and increase activity progressively rather than alternating prolonged bed rest with sudden strenuous effort. Recovery varies with the operation, complications, baseline health and daily demands. Advice should connect increasing activity with symptom monitoring: expected tiredness can guide pacing, whereas new breathlessness, unilateral leg swelling, fever or worsening pain requires assessment rather than simple adjustment of exercise.

Apply it

A patient avoids all walking because she fears disrupting her abdominal wound. Explain a gradual walking plan with rest periods, discuss practical support at home and distinguish ordinary fatigue from symptoms that require medical assessment.

Common pitfall: Prolonged bed rest is not a general recovery strategy. Equally, feeling better does not mean that heavy tasks should immediately resume without a progressive return.

Abdominal hysterectomy — recovering well

Antenatal carenot stated

17.How should reduced fetal movements be recognised and assessed?

A reduction or change from the baby's usual movement pattern matters more than a universal daily count. Movements should continue up to and during labour. After 28 weeks, contact maternity services immediately about a change; assessment includes history, antenatal review and usually cardiotocography. Persistent concern, small uterine measurements or other risk factors may require ultrasound assessment of growth and amniotic fluid despite reassuring monitoring. Recurrent episodes need fresh assessment. A home heartbeat device cannot establish fetal wellbeing or replace this assessment.

Apply it

At 34 weeks, a patient reports reduced movements despite detecting a sound with a home Doppler. Arrange prompt maternity assessment. If monitoring is reassuring but movements remain reduced or growth is concerning, assess the need for ultrasound.

Common pitfall: Neither a detected heartbeat nor a previous normal visit excludes current compromise. Reduced movement should not be explained as normal crowding near term.

Your baby's movements in pregnancy

18.How should antenatal screening results be distinguished from a diagnosis?

Screening estimates the chance of a condition; a higher-chance result is not a confirmed fetal diagnosis. England's fetal anomaly screening pathway offers screening for trisomies and a separate scan for specified structural conditions. Following a higher-chance combined or quadruple result, options include further screening with NIPT or prenatal diagnosis, according to informed choice. NIPT remains screening. Explain the conditions assessed, possible results and limitations before testing. See the [NHS fetal anomaly screening programme](https://www.gov.uk/government/publications/fetal-anomaly-screening-programme-handbook/overview).

Apply it

A patient interprets a higher-chance screening result as proof that her baby has trisomy 21. Explain the difference between chance and diagnosis, then discuss further screening, diagnostic testing and declining further testing.

Common pitfall: Greater screening accuracy does not convert NIPT into a diagnostic test. Screening choices should reflect the patient's informed preferences.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

19.How does assessment distinguish a small fetus from concerning growth restriction?

An estimated fetal weight below the 10th centile identifies a small fetus, but some small babies are constitutionally healthy. Growth restriction means the fetus has not grown as expected. Assess growth over time, amniotic fluid and Doppler blood flow, alongside maternal findings and fetal heart-rate assessment. Umbilical artery Doppler helps identify compromise and informs surveillance and birth planning. Very small size, early presentation or abnormal Doppler findings warrant specialist assessment. See [RCOG information on having a small baby](https://www.rcog.org.uk/for-the-public/browse-our-patient-information/having-a-small-baby/).

Apply it

A fetus measures below the 10th centile. Review the growth trajectory and arrange appropriate Doppler and wellbeing assessment rather than deciding from size alone that either immediate birth or routine reassurance is appropriate.

Common pitfall: Small size and pathological growth restriction are not interchangeable. A reassuring heart-rate trace does not assess growth or placental blood flow.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

20.What distinguishes chorionic villus sampling from amniocentesis?

Both are ultrasound-guided invasive procedures that obtain material for specified chromosomal or genetic diagnostic tests. Chorionic villus sampling obtains placental tissue and is usually performed at 11–14 weeks. Amniocentesis obtains amniotic fluid and is usually performed at 15–20 weeks, although either may be performed later when indicated. Explain the procedure, miscarriage risk and the scope of the laboratory analysis: a diagnostic sample does not test for every possible condition. See the [NHS prenatal diagnosis handbook](https://www.gov.uk/government/publications/fetal-anomaly-screening-programme-handbook/prenatal-diagnosis).

Apply it

At 12 weeks, a patient wants diagnostic testing after a higher-chance screening result. Discuss CVS as an earlier sampling option and amniocentesis later, including what the proposed analysis can establish and the procedural risks.

Common pitfall: The sampling procedure and the laboratory test answer different questions. Neither a normal targeted result nor an invasive sample guarantees absence of all fetal abnormalities.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

Maternal medicinenot stated

21.How can pre-eclampsia occur without proteinuria?

Pre-eclampsia is a pregnancy-associated hypertensive disorder that can involve the liver, kidneys, blood-clotting system, brain and placenta. Protein in the urine is an important finding, but its absence does not exclude the condition when hypertension accompanies other organ dysfunction. Severe headache, visual disturbance, pain below the ribs, abnormal blood tests or concerns about fetal growth can therefore be decisive. Assess maternal symptoms, blood pressure, laboratory results and fetal wellbeing together rather than using urine protein as a solitary gatekeeper.

Apply it

A patient at 33 weeks has new hypertension, visual disturbance and abnormal liver tests, but no protein on urine testing. Arrange urgent assessment for pre-eclampsia rather than excluding it on the basis of the urine result.

Common pitfall: Hypertension plus negative urine protein is not automatically uncomplicated gestational hypertension. Other maternal organ involvement can establish a much more concerning clinical picture.

Pre-eclampsia

22.Why does pre-eclampsia surveillance continue after birth?

Delivery removes the placenta but does not immediately reverse all maternal effects of pre-eclampsia. The condition can persist, worsen or first become apparent after birth, so blood-pressure monitoring and attention to symptoms remain important during the postnatal period. Severe headache, visual symptoms, upper abdominal pain or feeling markedly unwell require prompt assessment. Explain this continuing risk before discharge so that a patient does not interpret the end of pregnancy as proof that hypertensive complications are no longer possible.

Apply it

Four days after delivery, a patient previously treated for pre-eclampsia develops severe headache and blurred vision. Arrange urgent clinical assessment and blood-pressure review rather than attributing the symptoms to ordinary postnatal tiredness.

Common pitfall: Birth is not an immediate all-clear for maternal hypertension. A normal appearance at discharge does not remove the need to respond to later warning symptoms.

Pre-eclampsia

23.When is repeat glucose testing needed after previous gestational diabetes?

Previous gestational diabetes increases the likelihood of recurrence in another pregnancy. Testing is therefore offered early, using an oral glucose tolerance test or appropriate glucose monitoring. If an early oral glucose tolerance test is normal, repeat testing is offered at 24–28 weeks because pregnancy-related insulin resistance increases as gestation progresses. An early reassuring result does not assess the metabolic demands of later pregnancy. Connect the testing plan to the previous history rather than waiting for symptoms of hyperglycaemia.

Apply it

A patient with gestational diabetes in her previous pregnancy has a normal early oral glucose tolerance test this time. Explain why another test at 24–28 weeks remains appropriate despite the reassuring early result.

Common pitfall: A normal early test does not eliminate later gestational diabetes. The changing metabolic effects of pregnancy make the timing of reassessment clinically important.

Gestational diabetes

24.Why can a baby develop hypoglycaemia after maternal gestational diabetes?

Maternal glucose crosses the placenta and can stimulate increased fetal insulin production. After birth, the placental glucose supply stops while the baby's insulin effect may remain high, creating a risk of neonatal hypoglycaemia. This explains the importance of early feeding and postnatal glucose monitoring in babies of mothers with diabetes. The risk reflects the baby's metabolic transition, so apparent wellness or a normal maternal glucose measurement after delivery does not remove the need for the planned newborn assessment.

Apply it

A term baby born after a pregnancy complicated by gestational diabetes looks well. Support early feeding and the planned glucose checks because neonatal hypoglycaemia may develop despite an initially reassuring appearance after birth.

Common pitfall: Maternal glucose improving after delivery does not instantly normalise the baby's insulin response. Do not use the mother's postnatal result to cancel neonatal surveillance.

Gestational diabetes

Management of labournot stated

25.How does a balloon catheter ripen the cervix?

A cervical balloon produces pressure and stretching at the cervix, encouraging cervical change and local physiological processes involved in labour. It offers a mechanical approach to ripening rather than administering a prostaglandin drug. Mechanical methods have a lower risk of uterine hyperstimulation than pharmacological ripening methods, although contractions, discomfort and other complications remain possible. The choice should reflect the clinical circumstances, the patient's preferences and the distinction between preparing the cervix and establishing effective labour.

Apply it

A patient needs cervical ripening and places particular value on reducing the chance of excessive contractions. Discuss balloon ripening, explaining its mechanical action, possible discomfort and the likelihood that further induction steps may still be needed.

Common pitfall: Lower hyperstimulation risk does not mean no risk or no need for monitoring. Cervical ripening also does not guarantee that established labour will follow immediately.

Mechanical Induction of Labour (Balloon Catheter)

26.Why may further induction steps be needed after balloon ripening?

Cervical ripening and the establishment of labour are related but distinct parts of induction. A balloon can soften and open the cervix without producing sustained effective contractions. After reassessment, breaking the waters and an oxytocin infusion may be considered when clinically appropriate. Explain the staged nature of induction before treatment begins so that removal or expulsion of the balloon is interpreted as progress in cervical preparation, rather than proof that the whole induction process is complete.

Apply it

After balloon ripening, a patient's cervix is more favourable but she has no regular contractions. Reassess her and discuss the next induction stage rather than describing the absence of contractions as automatic failure of cervical ripening.

Common pitfall: Balloon expulsion is not equivalent to established labour. Avoid promising a fixed delivery time based solely on the completion of the mechanical ripening stage.

Mechanical Induction of Labour (Balloon Catheter)

27.Why does a high presenting part increase cord prolapse risk?

When the presenting part does not closely occupy the pelvis, space remains through which the umbilical cord can descend after the membranes rupture. A high head, malpresentation or unstable lie therefore increases the risk of cord prolapse. Once the cord lies below or alongside the presenting part, compression may reduce fetal blood flow and oxygen delivery. Recognising the anatomical risk matters when assessing ruptured membranes or planning interventions that could release amniotic fluid around an unengaged presenting part.

Apply it

A patient with an unstable lie has ruptured membranes while the presenting part remains high. Recognise the increased prolapse risk and ensure prompt obstetric assessment rather than treating the situation as uncomplicated membrane rupture.

Common pitfall: Membrane rupture is not equally low risk in every presentation. The relationship between the presenting part and the pelvis changes the possibility of cord descent.

Umbilical cord prolapse in late pregnancy

28.How is cord compression reduced while urgent birth is arranged?

Cord prolapse is an obstetric emergency because compression can interrupt the baby's oxygen supply. Call for immediate help and reduce pressure on the cord while preparing urgent birth. In hospital, a clinician may elevate the presenting part manually; maternal positioning can also help reduce compression. These are temporary protective measures and do not resolve the need for delivery. The route of birth depends on which safe method can achieve birth promptly in the actual clinical circumstances.

Apply it

After membrane rupture, a prolapsed cord is felt and the fetal heart rate falls. Call the emergency team, relieve pressure by elevating the presenting part and prepare urgent birth while maintaining the protective manoeuvre.

Common pitfall: Repeatedly handling the cord or trying to push it back is not a substitute for decompression. Temporary improvement does not remove the need for urgent birth.

Umbilical cord prolapse in late pregnancy

Management of deliverynot stated

29.Which findings identify shoulder dystocia?

Shoulder dystocia occurs when the shoulders do not deliver with usual gentle axial traction after the head has delivered and additional obstetric manoeuvres are required. Retraction of the head towards the perineum may provide a visible clue, but recognition should rest on the actual delivery difficulty. Announce the emergency and summon appropriate help promptly. Increasing traction does not correct the underlying impaction and can expose the baby to injury while delaying the manoeuvres needed to release the shoulders.

Apply it

The head delivers but retracts towards the perineum, and the shoulders do not follow with gentle axial traction. Announce shoulder dystocia, call for help and begin the recognised manoeuvre sequence rather than pulling harder.

Common pitfall: Failure of restitution alone is not the entire diagnosis. Do not wait for a dramatic external sign when the shoulders already require additional manoeuvres for delivery.

Shoulder Dystocia — RCOG Green-top Guideline, third edition

30.How do McRoberts positioning and suprapubic pressure help shoulder dystocia?

McRoberts positioning hyperflexes the maternal hips, straightens the lumbosacral angle and rotates the pelvis cephalad, helping release the impacted shoulder. Directed suprapubic pressure adducts the anterior shoulder, reduces the bisacromial diameter and assists rotation into an oblique pelvic diameter. If external measures fail, subsequent options include internal rotation and delivery of the posterior arm, selected according to the circumstances and operator training. Maintain clear team communication and avoid excessive head traction. Fundal pressure can worsen impaction and must not be used.

Apply it

After recognition and a call for help, use McRoberts positioning with correctly directed suprapubic pressure. If the shoulders remain impacted, proceed promptly to an appropriate internal rotation manoeuvre or posterior-arm delivery rather than repeating ineffective external measures indefinitely.

Common pitfall: Suprapubic pressure acts on the shoulder; fundal pressure drives the fetus towards the obstruction. McRoberts changes pelvic orientation rather than enlarging the bony pelvis.

Shoulder Dystocia — RCOG Green-top Guideline, third edition

31.When can episiotomy assist shoulder dystocia management?

Shoulder dystocia is principally a bony impaction, so cutting the perineum does not itself free the shoulder. Episiotomy may be considered when additional space is needed to introduce a hand for internal manoeuvres. Its role is therefore to facilitate access, rather than to treat the obstruction directly. Distinguish the reason for an incision from the manoeuvre that actually changes the shoulder position, and avoid making episiotomy an automatic response to every shoulder dystocia.

Apply it

Initial external manoeuvres have not released the shoulders, and restricted perineal access prevents the operator from performing an internal manoeuvre. Consider episiotomy to improve access while continuing the coordinated emergency response and appropriate shoulder-release techniques.

Common pitfall: An episiotomy enlarges soft-tissue access, not the maternal bony pelvis. Performing it alone can delay the manoeuvre needed to resolve the actual impaction.

Shoulder Dystocia — RCOG Green-top Guideline, third edition

32.Which route of birth is appropriate after cord prolapse?

The aim after cord prolapse is prompt birth while reducing cord compression. Caesarean birth is usually needed when vaginal birth is not imminent. If the cervix is fully dilated and an assisted vaginal birth can safely achieve delivery more quickly, that may be the appropriate route. The decisive issue is the fastest safe achievable birth in the actual circumstances, rather than a rule that every prolapse must be managed by the same operative method.

A prolapsed cord is diagnosed with an incompletely dilated cervix and a high fetal head. Continue decompression and prepare urgent caesarean birth because safe vaginal delivery is not immediately achievable in these circumstances.

Common pitfall: Do not delay an achievable prompt vaginal birth solely to follow a caesarean default. Conversely, a high head and incomplete dilatation make vaginal birth an unrealistic immediate solution.

33.How should uterine atony causing postpartum haemorrhage be managed?

Uterine contraction compresses placental-site vessels; atony permits continued bleeding. Summon help and undertake bleeding control, resuscitation and cause assessment concurrently. Massage the uterus, give appropriate uterotonic treatment, empty the bladder and administer early intravenous tranexamic acid. Tranexamic acid inhibits clot breakdown and should be started as soon as possible within three hours of birth. Establish intravenous access, give crystalloid fluids, monitor blood loss and vital signs, and sample blood for haemoglobin, coagulation studies and cross-matching. Prepare transfusion when clinically indicated. Examine for genital tract trauma, retained tissue and coagulopathy alongside initial treatment because causes can coexist. Escalate promptly to tamponade or surgery when necessary. See the [WHO PPH treatment bundle](https://cdn.who.int/media/docs/default-source/reproductive-health/maternal-health/bleeding-after-birth-provider-guide.pdf?sfvrsn=1379ee29_4).

Apply it

Heavy bleeding and a soft uterus develop soon after birth. Assign simultaneous roles for massage and uterotonics, early intravenous tranexamic acid, vascular access and resuscitation, blood sampling, and examination of the placenta and genital tract.

Common pitfall: Do not wait for uterotonics to fail before giving tranexamic acid or assessing additional causes. Improved tone does not prove haemorrhage has stopped.

Heavy bleeding after birth (postpartum haemorrhage) · MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

34.When does later postnatal bleeding suggest secondary postpartum haemorrhage?

Secondary postpartum haemorrhage is abnormal or heavy vaginal bleeding between 24 hours and 12 weeks after birth. It is often associated with uterine infection and may involve retained placental tissue. Increasing bleeding, unpleasant-smelling discharge or feeling unwell should prompt assessment rather than reassurance that all postnatal bleeding is normal lochia. The clinical response depends on bleeding severity and the patient's condition; significant ongoing loss can require urgent hospital treatment even well after the initial birth admission.

Apply it

Ten days after delivery, a patient develops increasing bleeding and offensive discharge after previously improving. Assess for secondary postpartum haemorrhage, including infection and retained tissue, rather than assuming that the change is ordinary postnatal lochia.

Common pitfall: Timing after discharge does not make heavy bleeding benign. Compare the current amount, trend and associated symptoms with the expected pattern of improving recovery.

Heavy bleeding after birth (postpartum haemorrhage)

35.Which postnatal symptoms suggest postpartum psychosis?

Postpartum psychosis can present with hallucinations, delusions, severe mood disturbance, confusion, agitation and markedly altered behaviour. It often begins suddenly in the early weeks after birth and can deteriorate rapidly. These features require urgent assessment as a medical emergency, with attention to the safety of the mother and baby. Distinguish psychotic beliefs or perceptual disturbance from ordinary postnatal emotional lability; the presence of a clear delusion should not be attributed simply to sleep deprivation or adjustment to parenthood.

Apply it

One week after birth, a patient sleeps very little, becomes unusually energetic and says television presenters are sending instructions about her baby. Arrange urgent emergency mental health assessment and immediate support for mother and infant safety.

Common pitfall: Calling hallucinations or delusions 'baby blues' can dangerously delay care. A patient may lack insight into the illness, so family observations can be crucial.

Postpartum psychosis

36.How should a history of bipolar disorder affect postnatal planning?

Bipolar disorder and a previous episode of postpartum psychosis increase the risk of postpartum psychosis. Identify the history during pregnancy and arrange specialist planning rather than waiting for symptoms after birth. A useful plan identifies warning signs, who to contact and how urgent care will be accessed. Family or other trusted supporters can help recognise sudden changes in sleep, mood, thinking or behaviour. Risk does not mean illness is inevitable, but it justifies proactive specialist involvement.

Apply it

A pregnant patient with bipolar disorder asks about care after birth. Arrange specialist perinatal mental health planning and discuss early warning signs with her and, with her agreement, a trusted supporter before delivery.

Common pitfall: A symptom-free antenatal visit does not remove the elevated postnatal risk. Equally, a risk factor alone should not be presented as a certain future episode.

Postpartum psychosis

Gynaecological problemsnot stated

37.Why is hysteroscopy useful for a suspected endometrial polyp?

Hysteroscopy passes a narrow telescope through the cervix to inspect the uterine cavity directly. This can identify focal abnormalities such as polyps and may allow a targeted biopsy or treatment during the same attendance when suitable and agreed. It answers a cavity question that cannot always be settled by symptoms alone. Explain the proposed diagnostic and treatment components separately, including discomfort and alternatives, so that agreement to inspection is not assumed to authorise every possible additional intervention.

Apply it

A patient with intermenstrual bleeding has an ultrasound suggesting a focal cavity lesion. Discuss hysteroscopy to inspect the suspected polyp directly and explain whether biopsy or removal could be offered during the same visit.

Common pitfall: Direct visualisation does not make every lesion harmless or eliminate the possible need for histology. Obtain agreement for any planned treatment as well as inspection.

Outpatient hysteroscopy

38.What should happen if outpatient hysteroscopy becomes too painful?

A patient can ask for outpatient hysteroscopy to stop at any time. Pain varies, and the ability to complete the procedure without anaesthesia should never be presumed from another patient's experience. Stop when requested, address the patient's immediate needs and discuss alternative arrangements, which may include different analgesia or a procedure with anaesthesia. A clinically useful investigation remains dependent on ongoing consent; diagnostic convenience does not justify continuing through an explicit request to stop.

Apply it

During hysteroscopy, a patient says the pain is intolerable and asks the clinician to stop. Stop the procedure, check her wellbeing and arrange a discussion of alternative ways to complete the necessary assessment.

Common pitfall: A brief expected remaining duration does not justify overriding a request to stop. Earlier consent does not remove the patient's control during the procedure.

Outpatient hysteroscopy

39.Why does a normal scan not exclude endometriosis?

Ultrasound and magnetic resonance imaging can identify some endometriosis-related abnormalities, including ovarian endometriomas and features of deeper disease, but normal imaging does not exclude endometriosis. Superficial disease may not be visible. Persistent cyclical pelvic pain, painful periods, deep pain during intercourse or cyclical bowel symptoms therefore remain clinically meaningful despite a normal scan. Further management depends on symptoms, examination, reproductive priorities and response to treatment rather than an assumption that normal imaging proves the absence of disease.

Apply it

A patient has disabling cyclical pelvic pain and deep dyspareunia, but her ultrasound is normal. Continue a clinical assessment for endometriosis and discuss appropriate management rather than dismissing the symptoms because imaging found no abnormality.

Common pitfall: Normal imaging is not a universal exclusion test. Conversely, symptoms alone do not prove that every pain episode is caused by endometriosis.

Endometriosis

40.How do symptom goals guide endometriosis treatment choices?

Endometriosis management should reflect pain severity, effects on daily life, previous treatment and reproductive plans. Hormonal treatments can reduce symptoms by suppressing cyclical hormonal activity, while surgery may be considered in selected circumstances. No single intervention suits every patient or guarantees permanent symptom resolution. Establish whether the immediate goal is pain control or pregnancy because these goals alter the suitability of suppressive treatment. Shared decisions should include treatment burdens, possible recurrence and the patient's priorities.

Apply it

A patient with suspected endometriosis wants symptom relief and is not currently trying to conceive. Discuss analgesic and hormonal options in relation to her preferences, previous treatment experience and the effects of pain on daily life.

Common pitfall: Choosing treatment solely from an imaging label overlooks symptom burden and reproductive priorities. Symptom improvement with hormones also does not establish a definitive diagnosis.

Endometriosis

Subfertilitynot stated

41.Which findings support an adult diagnosis of polycystic ovary syndrome?

Adult PCOS is diagnosed using at least two of three features after excluding alternative causes: clinical or biochemical hyperandrogenism, irregular or absent menstrual periods reflecting ovulatory dysfunction, and polycystic ovarian morphology on ultrasound. Ovarian appearance alone is insufficient. When irregular cycles and hyperandrogenism are both present, ultrasound is not required simply to supply a third feature. Distinguish this adult approach from adolescent assessment, where normal pubertal changes can complicate interpretation and adult criteria should not be applied mechanically.

Apply it

An adult has persistent irregular periods and clinical hyperandrogenism after alternative causes have been excluded. Explain that PCOS can be diagnosed without requiring an ultrasound to demonstrate polycystic ovarian morphology as an additional mandatory feature.

Common pitfall: Polycystic-looking ovaries alone do not establish the syndrome. These adult criteria should not be transferred without qualification to adolescents undergoing normal pubertal development.

Polycystic ovary syndrome — WHO, 22 January 2026

42.How should initial fertility investigation assess both partners?

Assess both partners in parallel. Establish duration of attempts, sexual difficulties, previous pregnancies, relevant infections, operations, medicines and menstrual pattern. Investigate semen quality alongside ovulation and uterine or tubal factors. Semen analysis assesses concentration, motility and morphology; an abnormal first result needs confirmation. NICE recommends repeating ideally after three months, but promptly for azoospermia or severe oligozoospermia. Persistent abnormalities warrant male examination and consideration of hormone testing. See [NHS fertility assessment](https://www.nhs.uk/conditions/infertility/diagnosis/) and [NICE male-factor investigation](https://www.nice.org.uk/guidance/ng257/chapter/Investigation-of-fertility-problems-and-management-strategies).

Apply it

A couple has tried for 18 months. The woman has irregular cycles and her partner's first semen analysis shows reduced motility. Investigate ovulatory dysfunction and arrange confirmatory semen testing concurrently; one abnormality does not explain away the other.

Common pitfall: Previous paternity does not replace current semen assessment. An abnormal semen result also does not remove the need to investigate relevant female factors.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

43.How do timing and test purpose affect interpretation of female fertility investigations?

Progesterone assesses recent ovulation when sampled about seven days before the expected next period; day 21 fits a 28-day cycle, not every cycle. A low mistimed result cannot establish anovulation. Irregular cycles may require gonadotrophin assessment. Ultrasound assesses pelvic structure, while hysterosalpingography or contrast ultrasound evaluates tubal patency. Laparoscopy may be appropriate when pelvic disease or tubal damage is suspected. These investigations answer complementary questions. See [NHS progesterone interpretation](https://www.gloshospitals.nhs.uk/our-services/services-we-offer/pathology/tests-and-investigations/progesterone/) and [NHS fertility investigations](https://www.nhs.uk/conditions/infertility/diagnosis/).

Apply it

A woman with regular 35-day cycles has a low progesterone result on day 21. Repeat at approximately day 28 before concluding that ovulation failed. Her previous pelvic inflammatory disease separately raises concern about tubal damage, even if ovulation is demonstrated.

Common pitfall: Evidence of ovulation does not establish tubal patency. A normal routine pelvic scan does not answer every tubal or endometriosis-related question.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

44.How does the other fallopian tube affect ectopic surgery decisions?

When surgery is needed for a tubal ectopic pregnancy, the condition of the other tube affects the balance between removing the affected tube and attempting tube-preserving surgery. With a healthy opposite tube, removal of the affected tube is commonly advised. If the other tube is damaged or absent, preserving the affected tube may deserve consideration. Tube-preserving surgery carries a risk of persistent pregnancy tissue and requires follow-up. Discuss fertility implications without assuming that retaining an abnormal tube guarantees better reproductive outcomes.

Apply it

A patient requiring surgery for a tubal ectopic pregnancy has a previously removed opposite tube. Discuss the potential role and limitations of tube-preserving surgery, including the possibility of additional treatment and the need for follow-up.

Common pitfall: Preserving anatomy does not guarantee normal tubal function. Conversely, routine removal without considering the opposite tube can overlook an important fertility-related decision.

Ectopic pregnancy

Sexual and reproductive healthnot stated

45.Why does migraine with aura change combined pill suitability?

Migraine with aura is a reason to avoid the combined oral contraceptive pill because the oestrogen-containing method is unsuitable in this vascular-risk context. Ask specifically about preceding visual, sensory or other neurological symptoms rather than documenting only the word migraine. A young age or absence of smoking does not cancel this concern. Discuss an appropriate alternative after assessing the person's full history, distinguishing the combined pill from contraceptive methods that do not contain oestrogen.

Apply it

A patient requesting the combined pill describes a spreading visual disturbance before recurrent headaches. Recognise possible migraine aura, clarify the history and discuss suitable alternatives instead of assuming that her young age makes combined contraception appropriate.

Common pitfall: All headaches are not equivalent, and aura matters. Do not generalise a restriction on the combined pill into a claim that every contraceptive method is unsuitable.

Who can take the combined pill

46.How do condoms add protection when another contraceptive is used?

Condoms provide a barrier that can reduce transmission of sexually transmitted infections as well as prevent pregnancy. Another effective contraceptive method may address pregnancy risk without providing this infection protection. Discuss these as separate goals so that a patient can choose condoms alongside a pill, implant or intrauterine method when relevant. Protection depends on correct, consistent use, and condoms reduce rather than eliminate infection risk. The decision should reflect exposure risk and the patient's preferences without assuming that contraceptive reliability implies infection safety.

Apply it

A patient with an implant asks whether condoms still have a purpose with a new partner. Explain that the implant addresses pregnancy prevention, while condoms provide additional protection against sexually transmitted infections when used correctly.

Common pitfall: High contraceptive effectiveness does not imply protection from infection. Avoid presenting condom use as unnecessary simply because another method provides strong pregnancy prevention.

Condoms

47.Which condom-use errors increase the chance of failure?

Use a new condom for each act of sex and put it on before genital contact. Check the packaging and expiry date, avoid damage when opening it, and follow the product instructions. Using two condoms together can create friction and increase breakage risk. Oil-based lubricants can damage latex condoms, so select a compatible lubricant. Correct technique addresses preventable mechanical failures, but it should accompany a discussion of what to do if a condom slips or breaks.

Apply it

A couple uses two external condoms together because they think this doubles protection. Explain the friction-related failure risk and demonstrate correct use of one condom with a compatible lubricant and a new condom for each act.

Common pitfall: More layers do not necessarily mean more protection. Condom compatibility and technique matter, and instructions can differ with the material and type of product.

Condoms

48.Which time-sensitive actions follow condom failure?

Assess pregnancy and infection risks separately, including other contraception and all unprotected intercourse in the current cycle. Levonorgestrel is normally taken within 72 hours and ulipristal acetate within 120 hours after intercourse. Oral emergency contraception delays ovulation and is unlikely to work after ovulation. The copper IUD is the most effective emergency method. In a natural menstrual cycle, it can be inserted within five days after the first unprotected intercourse or within five days after the earliest likely ovulation date, whichever is later. Establish menstrual history before applying this exception. See the [FSRH emergency contraception guideline](https://www.cosrh.org/Common/Uploaded%20files/documents/fsrh-guideline-emergency-contraception03dec2020-amendedjuly2023-11jul.pdf) and [NHS emergency contraception guidance](https://www.nhs.uk/contraception/emergency-contraception/). A concerning HIV exposure requires urgent PEP assessment as soon as possible within 72 hours; do not await infection testing. See [NHS HIV guidance](https://www.nhs.uk/conditions/hiv-and-aids/).

Apply it

A patient in a natural cycle presents seven days after her first unprotected intercourse. Her earliest likely ovulation date was three days ago. Copper IUD insertion remains within the five-day ovulation-based window, despite intercourse being more than five days ago. Oral emergency contraception is unlikely to help if ovulation has already occurred.

Common pitfall: Counting only from the most recent intercourse can miss pregnancy risk from earlier intercourse. Counting only five days from intercourse can incorrectly exclude an eligible copper IUD user. Emergency contraception does not prevent infection; STI testing and urgent HIV PEP assessment address separate risks.

Condoms

Early pregnancy carenot stated

49.What does pregnancy of unknown location mean?

Pregnancy of unknown location describes a positive pregnancy test when ultrasound has not identified a pregnancy inside or outside the uterus. Possible explanations include a very early intrauterine pregnancy, a pregnancy that has already ended or an ectopic pregnancy. It is a temporary classification rather than a final diagnosis. Follow-up uses clinical review, serial pregnancy hormone measurements and repeat ultrasound as appropriate. Symptoms remain important throughout, because an initially inconclusive scan does not exclude a dangerous ectopic pregnancy.

Apply it

A stable patient has a positive pregnancy test but no pregnancy is visible on transvaginal ultrasound. Explain the possible outcomes, arrange structured follow-up and provide clear instructions to seek urgent help if pain, dizziness or collapse develops.

Common pitfall: An empty uterus does not by itself prove miscarriage or ectopic pregnancy. A single hormone result also cannot establish where the pregnancy is located.

Ectopic pregnancy

50.Which early pregnancy symptoms suggest a ruptured ectopic pregnancy?

Severe abdominal pain, shoulder-tip pain, dizziness, fainting or collapse in early pregnancy can indicate internal bleeding from a ruptured ectopic pregnancy. Vaginal bleeding may be absent or limited because the major blood loss can be into the abdomen. This pattern requires emergency assessment and resuscitation, rather than routine outpatient follow-up. Consider ectopic pregnancy even when the patient has not yet confirmed pregnancy or does not report a classic combination of symptoms, especially when circulatory compromise is present.

Apply it

A patient with a late period develops severe one-sided abdominal pain, shoulder-tip pain and faintness, with little vaginal bleeding. Treat this as a possible ruptured ectopic pregnancy and arrange immediate emergency assessment and resuscitation.

Common pitfall: Small visible blood loss does not exclude major internal haemorrhage. Waiting for a complete classic symptom pattern can delay care in an unstable patient.

Ectopic pregnancy

51.Why must antiphospholipid antibody positivity be persistent?

Antiphospholipid syndrome assessment combines a compatible clinical history with persistent antiphospholipid antibodies. RCOG patient guidance describes two positive tests at least 12 weeks apart and testing at least six weeks after a miscarriage. A single positive result can be transient and is insufficient to establish the syndrome. Interpret the laboratory finding alongside the pregnancy-loss or thrombosis history, rather than treating an isolated abnormal result as a complete explanation for recurrent miscarriage or an automatic indication for treatment.

Apply it

A patient investigated after recurrent miscarriage has one positive antiphospholipid antibody test. Explain why appropriately timed repeat testing and assessment of the clinical history are needed before confirming antiphospholipid syndrome or assigning a treatment plan.

Common pitfall: One positive antibody result is not a diagnosis of antiphospholipid syndrome. Persistence and relevant clinical features matter; indiscriminate treatment can expose patients to avoidable harm.

Recurrent miscarriage

52.How does uterine assessment contribute to recurrent miscarriage investigation?

Assessment of uterine anatomy can identify structural differences that may contribute to pregnancy loss. RCOG describes pelvic ultrasound, with further imaging when a uterine difference is suspected, as part of recurrent miscarriage assessment. This investigates a different mechanism from chromosomal, endocrine or antiphospholipid causes. An anatomical finding must be interpreted carefully because identifying a difference does not automatically prove causation or establish that surgery will improve the chance of a live birth in that individual patient.

Apply it

A patient with recurrent miscarriage asks why ultrasound is needed after blood tests. Explain that imaging evaluates uterine structure, a separate possible contributor, and that any abnormal finding will require interpretation before considering further investigation or intervention.

Common pitfall: Normal blood tests do not assess uterine anatomy. Equally, finding an anatomical difference does not by itself justify surgery or prove the cause of every loss.

Recurrent miscarriage

Gynaecological oncologynot stated

53.How do morphology and clinical context distinguish low-risk postmenopausal cysts from concerning masses?

An asymptomatic unilateral, unilocular simple ovarian cyst measuring 3 cm or less needs no routine follow-up under the December 2025 RCOG amendment. This narrow category differs from masses showing multilocularity, solid areas, bilateral lesions, ascites or metastases. These features contribute to RMI I and require integrated risk assessment. CA125 cannot independently diagnose or exclude malignancy: it may be normal in cancer or raised in benign disease. Symptoms and non-simple morphology move a patient outside the specific small-simple-cyst exception.

Apply it

Explain why an incidental 2.5 cm simple cyst in an asymptomatic postmenopausal patient can be managed differently from a similarly sized lesion containing solid areas. A normal-range CA125 does not cancel concerning morphology.

Common pitfall: The 3 cm exception requires every low-risk descriptor. Neither size nor CA125 alone supplies a reliable reassurance rule for other adnexal masses.

54.When do cervical findings require an urgent suspected-cancer referral?

A cervix whose appearance is consistent with cancer requires an immediate suspected-cancer pathway referral. Do not wait for screening results or completion of treatment for a presumed benign cause. England's programme guidance specifies assessment within two weeks for suspicious cervical appearance or symptoms consistent with cervical cancer. Persistent postcoital bleeding or unexplained discharge with a non-suspicious examination still needs assessment for common causes and specialist review when unexplained or persistent; the examination determines whether an overt cancer concern is already present. Colposcopy identifies abnormal areas, and biopsy establishes histology. CIN is not synonymous with invasive cancer. See [NHS cervical referral guidance](https://www.gov.uk/government/publications/cervical-screening-programme-and-colposcopy-management/2-providing-a-quality-colposcopy-clinic) and [cervical cancer investigations](https://www.nhs.uk/conditions/cervical-cancer/tests-and-next-steps/).

Apply it

A patient with postcoital bleeding has a visibly suspicious cervical lesion. Make the suspected-cancer referral now, even if an infection is also possible or a previous screening result was reassuring.

Common pitfall: Routine screening does not investigate symptoms. A plausible benign cause must not delay referral when the cervix itself looks malignant.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

55.How is RMI I calculated and used?

RMI I equals the ultrasound multiplier multiplied by the menopausal multiplier and CA125. The menopausal multiplier is three after menopause. The ultrasound multiplier is zero for no listed suspicious features, one for one feature and three for at least two. RCOG uses a threshold of 200 to identify patients needing further assessment with CT and referral to a gynaecological oncology multidisciplinary team. RMI is a triage tool, not histological proof, and concerning clinical findings still require appropriate interpretation.

Apply it

A postmenopausal patient has solid areas and multilocularity, with CA125 of 24. Use U = 3 and M = 3: RMI I is 3 × 3 × 24 = 216, exceeding the referral threshold.

Common pitfall: Do not substitute the number of ultrasound features for the multiplier. A normal-range CA125 can still produce an RMI above 200 when other multipliers are high.

Ovarian Cysts in Postmenopausal Women — guideline PDF, amended December 2025

56.How does postmenopausal bleeding lead to assessment for endometrial cancer?

Postmenopausal bleeding means unexplained vaginal bleeding more than 12 months after menstruation stopped because of menopause. NICE recommends a suspected-cancer pathway referral for endometrial cancer in patients aged 55 or over with unexplained postmenopausal bleeding that cannot be attributed to HRT. Consider the same pathway below age 55. See the [NICE symptom-based referral recommendations](https://www.nice.org.uk/guidance/ng12/chapter/Recommended-actions-organised-by-symptom-and-findings-of-primary-care-investigations). Examination helps establish the bleeding source. Transvaginal ultrasound assesses the uterus and endometrium; endometrial biopsy provides tissue for histological diagnosis. Hysteroscopy permits direct cavity inspection and targeted sampling when indicated. Atrophy and polyps are possible benign causes, but neither should be assumed without assessment.

Apply it

A 64-year-old who stopped menstruating at 51 and takes no HRT reports new vaginal spotting. This meets the definition of postmenopausal bleeding and the NICE recommendation for suspected-cancer pathway referral. Refer promptly even if the bleeding was scant or occurred only once. Explain that investigations distinguish benign causes from endometrial cancer and that biopsy establishes a tissue diagnosis when required.

Common pitfall: The small volume of spotting does not remove the referral indication. Cervical screening does not assess the endometrium. A suspected benign cause should not delay the indicated referral, and age below 55 does not exclude consideration of the suspected-cancer pathway.

Urogynaecology and pelvic floor problemsnot stated

57.How should symptoms and personal goals guide prolapse treatment?

Prolapse may cause a vaginal bulge, dragging discomfort and bladder, bowel or sexual symptoms, but visible prolapse can be minimally troublesome. Choose treatment according to symptom burden, function and preferences. Observation may suit an untroubled patient. Pelvic floor training can improve symptoms without guaranteeing anatomical reversal; specialist physiotherapy helps establish correct technique. Pessaries and surgery offer other options. Before surgery, discuss uterine preservation, intercourse, pregnancy plans, complications and recurrence because these priorities affect acceptable procedures.

Apply it

One patient with visible prolapse reports no functional difficulty and chooses observation. Another seeks active treatment and values uterine preservation and vaginal intercourse. Use those goals to compare physiotherapy, pessary management and suitable surgical options.

Common pitfall: Anatomical stage alone does not determine treatment. Successful anatomical repair cannot guarantee resolution of every bladder, bowel or sexual symptom.

Pelvic organ prolapse

58.How do stress and urgency urinary incontinence lead to different initial treatments?

Stress incontinence is leakage associated with effort, exertion, coughing or sneezing; urgency incontinence accompanies a compelling urge to void. Mixed incontinence includes both patterns, and treatment should address the predominant symptom. Offer supervised pelvic floor muscle training for at least three months for stress or mixed incontinence, confirming an effective contraction first. Offer bladder training for at least six weeks for urgency or mixed incontinence. See [NICE urinary incontinence recommendations](https://www.nice.org.uk/guidance/ng123/chapter/recommendations).

Apply it

Leakage with coughing without urgency supports stress incontinence and a pelvic floor training plan. Leakage while rushing to the toilet with urgency supports bladder training. A patient describing both needs both patterns assessed and prioritised.

Common pitfall: Leakage is a symptom, not a single mechanism. Treating all incontinence as a support defect can overlook urgency symptoms and misdirect treatment.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

59.How does a vaginal pessary manage prolapse?

A vaginal pessary mechanically supports prolapsed organs and can relieve symptoms without an operation. It may be used while awaiting surgery, when surgery is unsuitable or when the patient prefers ongoing conservative treatment. Fitting may require trying different sizes or shapes, and follow-up is important to assess comfort, support and vaginal health. Discuss practical aspects, including removal, replacement and possible effects on intercourse, because suitability depends on the device and the patient's circumstances rather than age alone.

Apply it

A patient with symptomatic prolapse wants relief but wishes to avoid surgery while caring for a relative. Offer discussion of a fitted vaginal pessary, including expected support, possible fitting adjustments and the need for ongoing review.

Common pitfall: A pessary supports rather than permanently repairs the prolapse. It should not be fitted as a one-off intervention without a clear plan for maintenance and review.

Pelvic organ prolapse

60.Which initial findings in urinary incontinence require assessment beyond symptom classification?

Perform urine dipstick testing to look for blood, glucose, protein, leucocytes and nitrites. Symptoms of voiding difficulty or recurrent urinary infection warrant post-void residual measurement, preferably with a bladder scan. Persistent bladder or urethral pain, suspected fistula, neurological disease, voiding difficulty or previous continence surgery may require specialist investigation. Haematuria or recurrent or persistent unexplained infection requires assessment under the relevant referral pathway. See [NICE assessment recommendations](https://www.nice.org.uk/guidance/ng123/chapter/recommendations).

Apply it

A patient reports leakage together with a weak stream and incomplete emptying. Assess residual urine rather than immediately treating presumed urgency alone. Investigate haematuria separately instead of attributing it to incontinence.

Common pitfall: A label of stress, urgency or mixed incontinence does not explain every associated finding. Emptying symptoms and haematuria can change the investigation pathway.

MRCOG Syllabus and Knowledge Requirements for Core Curriculum — April 2024

What to focus on during revision

The following are CertMedbry study suggestions. Use the official outline to check the full scope of your examination.

  • Recognise time-critical patterns: ruptured ectopic pregnancy, cord prolapse, shoulder dystocia, postpartum haemorrhage, pulmonary embolism and postpartum psychosis.
  • Distinguish what a test measures from what it cannot exclude: antenatal screening, CA125, fetal heartbeat detection, cardiotocography, pelvic imaging and a single pregnancy hormone result.
  • Practise transparent calculations: absolute risk reduction, relative risk, number needed to treat and RMI I.
  • Appraise allocation methods, outcome assessment, missing data and applicability before accepting a trial's numerical result.
  • Match teaching to an observed learning need and assess practical performance through supervised practice and specific feedback.
  • Investigate both partners in subfertility, interpreting semen analysis, ovulation testing and tubal assessment as complementary investigations.
  • Connect reproductive goals with treatment choices in endometriosis, PCOS, ectopic surgery, contraception and prolapse care.
  • Use individual priorities, supported decision making and the functional abilities required for capacity assessment to resolve clinical choices.
  • Study the complete Part 2 requirements in all 15 official knowledge areas; use these selective concepts to identify topics requiring broader revision.

A practical preparation plan

1. Map the official scope

Read the Part 2 requirements within each of the 15 knowledge areas in the April 2024 syllabus. Mark topics as secure, uncertain or unfamiliar. Keep the full outline beside this selective guide so that concentrated clinical examples do not become mistaken for the entire syllabus.

2. Build decision contrasts

For each concept, state the decisive cue and the tempting alternative. Practise contrasts such as screening versus diagnosis, normal imaging versus excluded disease, stress versus urgency incontinence, and symptom suppression versus fertility treatment.

3. Rehearse emergency sequences

Describe recognition, immediate protective action and definitive management for each emergency. For postpartum haemorrhage, rehearse simultaneous bleeding control, resuscitation and cause assessment, including early tranexamic acid. Explain why temporary improvement after cord decompression does not remove the need for prompt birth.

4. Calculate and appraise

Work risk calculations from original event counts. State outcomes and follow-up periods for NNT, and show each RMI I multiplier separately. Then assess whether study methods justify trusting a reported benefit: inspect allocation, blinding, exclusions, missing outcomes, precision and applicability.

5. Practise and explain clinical choices

Use the original SBA drills to choose one best answer and explain why each alternative is less appropriate. Add EMQ practice using broader clinical option lists. Review errors by knowledge area, missed discriminating cue and reasoning error. For practical learning, agree an observable objective, practise with feedback and reassess performance.

6. Space recall and update key guidance

Revisit flashcards at increasing intervals and explain the reasoning aloud. Check current primary guidance for topics you study in greater depth, including shoulder dystocia, antenatal screening and the postmenopausal ovarian cyst pathway.
