Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What hormone is released by the anterior pituitary to stimulate division of spermatogonia?

A	gnRH
B	FSH
C	LH
D	testosterone

Explanation:

Detailed explanation-1: -GnRH stimulates FSH release. 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.

Detailed explanation-2: -GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.

Detailed explanation-3: -Follicle-stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH) released by the hypothalamus. The pituitary gland also secretes luteinizing hormone (LH), another gonadotropin. FSH and LH are composed of alpha and beta subunits.

Detailed explanation-4: -LH stimulates the production of T, adjudged to be the cornerstone of effective spermatogenesis, secondary sexual characteristics and functions, as well as psychological and anabolic actions [4, 5, 13]. FSH, on the other hand, enhances T action by maintaining the supporting function of Sertoli cells on spermatogenesis.
