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: -Pituitary-derived FSH provides indirect structural and metabolic support for development of spermatogonia into mature spermatids via its membrane-bound receptor in Sertoli cells. FSH also play a crucial role in determination of the number of Sertoli cells and thus their capacity to maintain spermatogenesis.

Detailed explanation-3: -Gonadotrophin-releasing hormone (GnRH) is released from the hypothalamus and binds to receptors in the anterior pituitary gland to stimulate both the synthesis and release of follicle stimulating hormone (FSH) and luteinising hormone (LH).

Detailed explanation-4: -Follicle-stimulating hormone (FSH): This hormone stimulates the testes to produce sperm and stimulates the ovaries to produce eggs and estrogen.

Detailed explanation-5: -GnRH produced by the hypothalamus stimulates the production of both LH and FSH. FSH functions by stimulating ovarian follicular development in females and regulating spermatogenesis in males.
