Infertility evaluation: If a couple is having trouble conceiving, an FSH test can help determine if ovarian function is normal. Menstrual irregularities: To diagnose the underlying causes of irregular or absent menstrual periods. Menopause: To confirm if a woman is entering menopause. Polycystic Ovary Syndrome (PCOS): To help diagnose PCOS.
