When does FSH released?

Follicle-stimulating hormone (FSH) is released by the anterior pituitary gland in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. Its secretion typically occurs in a pulsatile manner, with higher levels released at the beginning of the menstrual cycle in females to stimulate ovarian follicle development. In males, FSH is released to support spermatogenesis in the testes. The release of FSH can be influenced by factors such as age, hormonal feedback, and the reproductive cycle.
