What is follicle stimulating hormone?

Follicle-stimulating hormone (FSH) is a glycoprotein hormone produced by the anterior pituitary gland. In females, it plays a crucial role in regulating the menstrual cycle and promoting the growth and maturation of ovarian follicles. In males, FSH is essential for spermatogenesis, stimulating the Sertoli cells in the testes to support sperm production. FSH levels are regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus and feedback from sex hormones.
