MICROANATOMY

Detailed explanation-1: -Follicle stimulating hormone (or FSH) is one of the gonadotrophic hormones; the other being luteinising hormone (or LH). Both are released by the pituitary gland into the bloodstream.

Detailed explanation-2: -Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In men, these hormones cause the testicles to make testosterone.

Detailed explanation-3: -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-4: -The gonads, responsible for the production of both sex steroids and gametes, under the influences of LH and FSH.
