FSH

Meaning

Follicle-Stimulating Hormone, a critical gonadotropin glycoprotein secreted by the anterior pituitary gland that plays a fundamental role in regulating reproductive function in both males and females. In women, FSH stimulates the growth and maturation of ovarian follicles and promotes estrogen production. In men, it is essential for stimulating spermatogenesis in the Sertoli cells of the testes. Clinical measurement of FSH levels is a standard diagnostic tool for assessing fertility, ovarian reserve, and hypothalamic-pituitary-gonadal axis function.
