follicle-stimulating hormone

Follicle-stimulating hormone (FSH) is a gonadotropin hormone secreted by the anterior pituitary gland under the control of gonadotrophin-releasing hormone (GnRH) from the hypothalamus. In females, FSH stimulates the growth and maturation of ovarian follicles and promotes estrogen production by the ovaries. It plays a key role in the menstrual cycle and ovulation. In males, FSH acts on the Sertoli cells of the testes to support spermatogenesis (sperm production) and normal reproductive function. FSH levels vary throughout life and may be used clinically to evaluate fertility, menstrual disorders, puberty, pituitary gland disorders, and gonadal function. Abnormal FSH levels may indicate conditions such as infertility, primary ovarian insufficiency, menopause, hypogonadism, or pituitary disease.

Follicle-stimulating hormone (FSH) is a hormone that helps control reproduction. In females, it helps eggs mature in the ovaries. In males, it helps the testes produce sperm. It is important for fertility and normal sexual development.

• Also called FSH • Hormone produced by the anterior pituitary gland • Controlled by gonadotrophin-releasing hormone (GnRH) • In females, stimulates the growth and maturation of ovarian follicles • Helps the ovaries produce estrogen and supports the menstrual cycle • In males, stimulates Sertoli cells and supports sperm production • Essential for fertility, puberty, and reproductive health • FSH blood tests are commonly used to evaluate fertility and hormone disorders • Abnormal FSH levels may occur in infertility, menopause, ovarian failure, hypogonadism, or pituitary disorders
