Hirsutism and Polycystic Ovary Syndrome

Clinical Scenario

Jemma Hayes, 27, calls about excess hair growth. Over the past 12 months she has noticed increasingly coarse, dark hair on her face (chin and jawline), abdomen, and chest. She also has irregular periods (cycles 45+ days with gaps of up to 10 weeks), mild acne on her chin, and difficulty losing weight (BMI 32). She is deeply embarrassed about the hair growth and has been spending significant time and money on hair removal. It is affecting her confidence, her relationship, and her willingness to be intimate with her partner.

What This Case Tests

Recognising the clinical features of PCOS (hirsutism, oligomenorrhoea, acne, weight management difficulty); ordering appropriate investigations (testosterone, SHBG, LH, FSH, TFTs, prolactin, HbA1c); discussing the diagnosis sensitively given its impact on femininity and self-image; presenting management options for both the hirsutism and the underlying PCOS; addressing the emotional and relational impact.

Common Mistakes Trainees Make

The three most common mistakes are: treating the hirsutism in isolation without diagnosing the underlying PCOS (the pattern of hirsutism, oligomenorrhoea, acne, and weight management difficulty is classic PCOS and requires metabolic screening), dismissing the emotional impact because the condition is not life-threatening (hirsutism profoundly affects body image, femininity, and quality of life), and not screening for metabolic complications of PCOS (insulin resistance, diabetes risk, cardiovascular risk).

The Consultation Challenge

Jemma has classic PCOS presenting through hirsutism. The Rotterdam criteria require 2 of 3: oligo/anovulation (irregular periods — present), clinical or biochemical hyperandrogenism (hirsutism and acne — present), and polycystic ovarian morphology on ultrasound (not yet assessed but likely given the other two criteria). The diagnosis is virtually certain clinically.

Start by acknowledging the impact. Hirsutism is deeply distressing for women — it challenges core aspects of femininity and self-image. Jemma has been suffering in silence, spending time and money on hair removal, and avoiding intimacy. Validate this: "I can see how much this is affecting you, and I want you to know we take this seriously. This is a medical condition, not something you should just have to manage on your own."

Take a thorough history. Hair growth: when it started, distribution (face, abdomen, chest — use the modified Ferriman-Gallwey score conceptually), rate of change. Menstrual history: cycle length, regularity, duration. Weight: BMI 32, difficulty losing weight despite effort. Acne: location, severity. Family history of PCOS, diabetes, or cardiovascular disease. Fertility plans (important for management choices).

Order investigations: total testosterone and SHBG (calculate free androgen index), LH and FSH (day 2-5 if possible — LH:FSH ratio >2:1 supports PCOS), 17-hydroxyprogesterone (exclude late-onset congenital adrenal hyperplasia if testosterone is significantly elevated), TFTs, prolactin, fasting glucose or HbA1c (metabolic screening), lipid profile, and pelvic ultrasound (polycystic morphology).

Management is multi-layered. For hirsutism: combined oral contraceptive (co-cyprindiol / Dianette contains cyproterone acetate which is anti-androgenic), topical eflornithine cream (slows facial hair growth), and continued hair removal methods. For the metabolic component: lifestyle modification (weight loss of 5-10% can significantly improve all PCOS symptoms), and consider metformin if insulin resistance is present. For menstrual regulation: the combined pill also addresses this. For acne: the combined pill plus topical retinoids if needed.

Address future fertility proactively. Jemma is 27 — she may want children in the future. PCOS is associated with anovulatory subfertility, but with treatment (weight loss, ovulation induction), the majority of women with PCOS conceive. Providing this information early prevents unnecessary anxiety.

Time check: Spend the first 4 minutes on history and validating the impact. By minute 7, explain the likely PCOS diagnosis. Arrange investigations between minutes 8-9. Use minutes 10-11 for the management plan. Reserve the final minute for emotional support and follow-up.

How Examiners Mark This Case

Data Gathering and Diagnosis: Examiners assess whether you recognise the PCOS pattern (hirsutism + oligomenorrhoea + weight difficulty + acne), apply the Rotterdam criteria, take a thorough hirsutism and menstrual history, and screen for secondary causes of hyperandrogenism (late-onset CAH, androgen-secreting tumour — rapid onset hirsutism with virilisation would suggest these). They look for appropriate investigation ordering including metabolic screening.

Clinical Management and Medical Complexity: Examiners expect a multi-layered management plan addressing hirsutism (anti-androgen contraception, eflornithine), menstrual irregularity (combined pill), metabolic risk (lifestyle, metformin consideration), and future fertility. They look for awareness that weight loss is the most effective single intervention for PCOS. A trainee who treats only the hirsutism without addressing the underlying PCOS will score poorly.

Relating to Others: Examiners assess whether you acknowledge the profound emotional impact of hirsutism on femininity and self-image, create a safe space for discussing an embarrassing symptom, and address the relationship and intimacy impact. Jemma should leave feeling that her condition has been taken seriously, that there is a clear diagnosis and treatment plan, and that she is not alone.

Example Opening

Strong opening: "Hello Jemma, thank you for calling. I can see this has been really affecting you, and I want you to know that what you're describing sounds like a recognised medical condition that we can treat. Can you tell me more about what you've been noticing?"

When explaining PCOS: "Based on what you're telling me — the hair growth, the irregular periods, the difficulty with weight, and the acne — I think you have a condition called polycystic ovary syndrome, or PCOS. It affects about 1 in 10 women and it's caused by a hormonal imbalance. The really important thing to know is that it's very treatable."

Avoid: "Lots of women have some facial hair — it's probably nothing to worry about." (Dismisses a significant medical condition and its emotional impact).

How This Appears in the SCA

Hirsutism with PCOS tests your ability to recognise a classic endocrine presentation, investigate appropriately, and manage both the dermatological symptom and the underlying condition. Examiners specifically assess whether you address the emotional impact and whether you screen for metabolic complications.

Key Statistic

PCOS affects approximately 1 in 10 women of reproductive age, making it the most common endocrine disorder in women. Hirsutism affects 70-80% of women with PCOS. Weight loss of 5-10% can improve menstrual regularity, reduce androgen levels, and improve fertility in overweight women with PCOS.

Frequently Asked Questions

What are the Rotterdam criteria for PCOS diagnosis?

PCOS is diagnosed when 2 of 3 criteria are met (after excluding other causes): oligo-anovulation (irregular or absent periods), clinical or biochemical hyperandrogenism (hirsutism, acne, or raised testosterone/free androgen index), and polycystic ovarian morphology on ultrasound (12+ follicles per ovary or ovarian volume >10mL). In Jemma's case, she meets criteria 1 and 2 clinically, making the diagnosis highly likely even before ultrasound.

What investigations should I order for suspected PCOS?

Hormonal: total testosterone and SHBG (calculate free androgen index), LH and FSH (day 2-5), 17-hydroxyprogesterone (exclude late-onset CAH). Metabolic: fasting glucose or HbA1c, lipid profile (PCOS increases cardiovascular risk). Other: TFTs, prolactin (exclude other causes of oligomenorrhoea). Imaging: pelvic ultrasound (polycystic morphology). A comprehensive investigation panel demonstrates thorough management.

What treatment options address hirsutism in PCOS?

Medical: combined oral contraceptive containing cyproterone acetate (co-cyprindiol/Dianette — anti-androgenic), spironolactone (off-licence, requires contraception as it is teratogenic). Topical: eflornithine cream (slows facial hair growth — takes 2-3 months for effect). Physical: continued hair removal (laser, IPL, electrolysis — can be funded by NHS dermatology in severe cases). Lifestyle: weight loss of 5-10% reduces androgen levels and can improve hirsutism significantly.

Should I screen for metabolic complications in PCOS?

Yes — PCOS is associated with insulin resistance, type 2 diabetes, dyslipidaemia, and increased cardiovascular risk. Screen with fasting glucose or HbA1c and lipid profile at diagnosis, and repeat periodically. Women with PCOS and BMI >30 are at particularly high risk. Metformin may be considered if insulin resistance is present, particularly if the patient is trying to conceive or has pre-diabetes. Demonstrating metabolic screening awareness shows comprehensive management.

How does PCOS affect fertility and what should I tell the patient?

PCOS is the most common cause of anovulatory subfertility, but the majority of women with PCOS conceive with treatment. Weight loss (even 5-10%) can restore ovulation in many cases. If weight loss alone is insufficient, ovulation induction with letrozole or clomifene is effective. IVF is available for resistant cases. At 27, Jemma has time — provide this reassurance proactively to prevent unnecessary anxiety about future fertility.
