The constellation of enlarged clitoris, persistent acne, menstrual irregularity, cysts on ovaries, facial hair, temporal balding, and increased libido is most characteristic of which condition?

• A. PCOS (PMOS)
• B. Endometriosis
• C. Ovarian cancer
• D. Uterine fibroids

Answer: (A)

Virilization with irregular menses and polycystic-appearing ovaries points to excess androgens from the ovaries, most classically seen in polycystic ovary syndrome. In PCOS, disrupted signaling in the hypothalamic-pituitary-ovarian axis—often with a higher LH to FSH ratio—stimulates theca cells to overproduce androgens. These androgens drive acne, facial and body hair growth, and, when levels are very high, clitoromegaly and androgenic hair loss on the temples. The androgen excess also interferes with normal ovulation, leading to irregular or absent menses, while insulin resistance commonly worsens androgen production and reduces sex hormone-binding globulin, increasing free testosterone. The ovarian morphology typically shows numerous small follicles, giving a cystic-appearing pattern.

Endometriosis doesn’t cause virilization and is driven by estrogen, presenting mainly with pelvic pain and infertility. Ovarian cancer and uterine fibroids produce symptoms like pelvic pressure or abnormal bleeding rather than a pattern of androgen excess and virilization.
