What is a common use of metformin in PCOS beyond glucose control?

• A. It is commonly used to improve insulin sensitivity
• B. It cures PCOS
• C. It increases testosterone production
• D. It rapidly induces ovulation in all patients

Answer: (A)

In PCOS, a major use of metformin beyond lowering glucose is to improve insulin sensitivity. By making tissues more responsive to insulin, it lowers circulating insulin levels. This matters because high insulin can drive the ovaries to produce more androgens, which contributes to irregular periods, acne, and other symptoms of PCOS. So reducing insulin helps decrease androgen levels and can support more regular ovulation in some people. It's not a cure for PCOS, and not everyone will ovulate just from metformin. Some patients may need additional treatments to induce ovulation, and metformin tends to lower testosterone rather than raise it.
