Which combination represents the classic triad of PCOS?

• A. Amenorrhea, obesity, and hirsutism.
• B. Menopause, weight loss, acne.
• C. Regular menses, obesity, hair loss.
• D. Infertility, diabetes, hypertension.

Answer: (A)

Polycystic ovary syndrome (PCOS) is typically characterized by irregular ovulation, signs of androgen excess, and common metabolic features. The combination that best represents this classic presentation is amenorrhea (a sign of ovulatory dysfunction), obesity, and hirsutism (excess hair growth due to elevated androgens). Amenorrhea reflects the lack of regular ovulation, which is central to PCOS. Hirsutism shows the androgen excess driving terminal hair growth. Obesity is a common accompanying feature that often worsens insulin resistance and hormone imbalances in PCOS. Other options don’t fit as well because they either show regular menses, which implies ovulation is occurring; or they emphasize features like menopause, hair loss, or unrelated metabolic conditions that are not the defining triad of PCOS.
