Which hormone is often found at abnormal levels in women with PCOS?

• A. Estrogen
• B. Testosterone
• C. Progesterone
• D. Follicle-stimulating hormone

Answer: (B)

Testosterone is often found at abnormal levels in women with polycystic ovary syndrome (PCOS). In PCOS, the ovaries can produce excess androgens, including testosterone, which can lead to various symptoms associated with the condition. Elevated testosterone levels are linked to issues such as hirsutism (excess hair growth), acne, and irregular menstrual cycles.

In women with PCOS, the hormonal imbalance primarily manifests as elevated androgens, disrupting normal ovarian function and leading to the characteristic features of the syndrome. This condition may also be associated with insulin resistance, which can further influence androgen production.

The other hormones listed—estrogen, progesterone, and follicle-stimulating hormone—do not typically show the same significant elevation as testosterone in PCOS, and their levels may present differently due to the hormonal imbalance. Understanding the role of testosterone in PCOS is crucial for diagnosing and managing the condition.
