Which statement correctly describes the diagnostic criteria for PCOS?

• A. Two of three features: oligo/anovulation, hyperandrogenism, and polycystic ovaries on ultrasound
• B. All three features are required
• C. Only one feature is required
• D. Diagnosis based on ultrasound alone

Answer: (A)

Two of the following three findings establish the diagnosis: irregular or absent ovulation, signs or lab evidence of excess androgens, and polycystic-appearing ovaries on ultrasound, with other causes ruled out. This approach, based on the Rotterdam criteria, reflects that no single feature is specific enough for PCOS. Hyperandrogenism can be clinical (hirsutism, acne, alopecia) or biochemical (elevated androgens). Oligo/anovulation means infrequent or absent menses. Ultrasound findings of multiple small follicles or enlarged ovaries support the diagnosis but ultrasound alone is not enough, as many women may have polycystic-appearing ovaries without other features, and imaging varies with age. Always exclude other conditions that can mimic PCOS, such as adrenal disorders, Cushing syndrome, and prolactin elevation.
