MICROANATOMY

Detailed explanation-1: -The hypothalamus produces GnRH, and it is released into the hypophyseal portal circulation to act on G-protein-coupled receptors at gonadotropic cells of the anterior pituitary. Those gonadotropic cells produce FSH and luteinizing hormone (LH) and release them into the peripheral circulation.

Detailed explanation-2: -Follicle stimulating hormone (FSH) is produced by the pituitary gland in the brain. It is an important hormone for normal functioning of the reproductive system in men and women.

Detailed explanation-3: -The follicle stimulating hormone (FSH) blood test measures the level of FSH in blood. FSH is a hormone released by the pituitary gland, located on the underside of the brain.

Detailed explanation-4: -The hypothalamus begins the process of ovulation by releasing GnRH in a pulsatile fashion. This pulsatile release causes the anterior pituitary to release LH and FSH, which then act on the ovarian follicle. This follicle is made up of 3 essential cells: theca cells, granulosa cells, and the oocyte.
