Follicle-Stimulating Hormone (FSH) is a pituitary hormone that plays a crucial role in reproductive function in both men and women. This test measures FSH levels in the blood to evaluate the hypothalamic-pituitary-gonadal axis and diagnose reproductive disorders. In women, FSH stimulates the growth and development of ovarian follicles during the menstrual cycle and works with luteinizing hormone (LH) to regulate ovulation. FSH levels vary throughout the menstrual cycle, with higher levels during the follicular phase and lower levels during the luteal phase. In men, FSH stimulates the Sertoli cells in the testes to support sperm production. Abnormal FSH levels can indicate problems with the pituitary gland, hypothalamus, or gonads. This test is commonly used to evaluate infertility, menstrual irregularities, delayed or precocious puberty, and pituitary function. FSH is often measured alongside LH to provide a complete picture of reproductive hormone status.
Patient Prep
