PCOS / PMOS Phenotype Quiz — A, B, C or D?
The Rotterdam criteria (2003, updated 2023) define 4 clinical phenotypes of PCOS/PMOS. This non-diagnostic tool helps you identify your probable profile to better prepare your medical consultation.
1.What are your menstrual cycles like?
2.Do you have persistent hormonal acne (jaw, neck, chest)?
3.Do you have excess hair growth on the face, chest, or abdomen (hirsutism)?
4.Do you notice significant hair thinning on the top of your scalp?
5.Have you had a pelvic ultrasound? What were the results?
6.Do you have signs of insulin resistance? (skin tags, dark patches in skin folds, strong sugar cravings, fatigue after meals)
7.What is your weight situation?
8.Has a blood test shown elevated testosterone or androgens?
9.Does your mother, sister, or close female relative have PCOS/PMOS or similar symptoms?

The Rotterdam 2003 criteria identify 3 diagnostic criteria for PCOS: (1) chronic anovulation, (2) clinical or biochemical hyperandrogenism, (3) polycystic ovarian morphology (PCOM). A diagnosis requires at least 2 of these 3 criteria.
| Phenotype | Anovulation | Hyperandrogenism | PCOM | Metabolic severity |
|---|---|---|---|---|
| A (classic) | ✓ | ✓ | ✓ | Most severe |
| B | ✓ | ✓ | — | Severe |
| C | — | ✓ | ✓ | Moderate |
| D | ✓ | — | ✓ | Milder |
The 2023 Update (ESHRE/Monash)
The international 2023 guideline (ESHRE + Monash University) confirms the 4 phenotypes while adding two important updates: (1) AMH can replace pelvic ultrasound as the third criterion; (2) specific pediatric criteria exist for adolescents (Monash 2023 pediatric chapter).

Frequently Asked Questions
- What are the 4 phenotypes of PCOS/PMOS?
- The Rotterdam 2003 criteria define 4 phenotypes: A (classic, all 3 criteria), B (anovulation + hyperandrogenism), C (hyperandrogenism + PCOM), D (anovulation + PCOM, mild). Phenotype A is the most severe metabolically.
- Is this quiz a medical diagnosis?
- No. This quiz is a non-diagnostic orientation tool to help you prepare your appointment. Only a doctor can diagnose PCOS/PMOS based on clinical examination, blood tests, and ultrasound.
- Which phenotype is most common?
- Phenotype A (classic) represents approximately 50-60% of PCOS diagnoses. It combines anovulation, hyperandrogenism, and polycystic ovarian morphology.
- Can my phenotype change over time?
- Yes. The phenotype can evolve, especially around puberty, pregnancy, and menopause. This is why reclassification at age 18 is recommended for adolescents.
- Does phenotype D mean my PCOS is milder?
- Phenotype D (anovulation + PCOM without clinical hyperandrogenism) is often considered less metabolically severe, but it can still cause significant fertility difficulties and irregular cycles.
- Should I do this quiz before my appointment?
- Yes, that is exactly its purpose. It helps you structure your observations and arrive at your appointment with precise, useful information for your doctor.
