FSH

Also written as: FSH — Follicle-Stimulating Hormone

Follicle-stimulating hormone, a gonadotropin essential for testicular development in boys and ovarian follicle maturation in girls.

Full Definition

Follicle-stimulating hormone (FSH) is a glycoprotein hormone produced by the anterior pituitary that regulates gonadal function and fertility. In pediatric endocrinology, FSH measurement helps evaluate pubertal development and diagnose reproductive disorders. FSH stimulates Sertoli cells in the testes to support spermatogenesis and granulosa cells in the ovaries to promote follicle development. Elevated FSH levels typically indicate primary gonadal dysfunction, while low levels suggest hypothalamic or pituitary disorders affecting the reproductive axis.

Usage

Usage note: Always capitalize when abbreviated; spell out on first mention in formal documents.
