Why This Biomarker Matters

FSH levels reflect reproductive health. Abnormal levels help diagnose menopause, infertility, pituitary disorders, and hormonal imbalances affecting sexual function.

Overview

Follicle-stimulating hormone (FSH) is produced by the pituitary gland and regulates reproductive function—controlling egg production in women and sperm production in men. A 24-hour urine FSH test measures hormone excretion, reflecting pituitary and reproductive gland function. Abnormal levels may indicate menopause, fertility problems, pituitary disorders, or hormonal imbalances. This test is often used to assess reproductive status and evaluate infertility or menopausal symptoms.
