The ESHRE/ASRM Rotterdam diagnostic criteria for PCOS require 2 of 3 features. Which of the following is NOT one of the Rotterdam criteria?
- A Elevated serum AMH >5 ng/mL ✓
- B Oligo-ovulation or anovulation
- C Clinical or biochemical hyperandrogenism
- D Polycystic ovarian morphology on ultrasound
Correct answer: A. Elevated serum AMH >5 ng/mL
Explanation
The Rotterdam 2003 criteria for PCOS require 2 of 3: (1) oligo/anovulation, (2) clinical or biochemical hyperandrogenism, (3) polycystic ovarian morphology on ultrasound (≥12 follicles 2–9 mm per ovary and/or ovarian volume >10 mL). Elevated AMH is a sensitive marker of PCOS and is being proposed for updated diagnostic criteria but is NOT part of the current Rotterdam 2003 consensus criteria.
