Text Solution

Verified by Experts

a) N//A
b) GnRH is secreted by the hypothalamus. The increased levels of GnRH stimulates the anterior pituitary which then secretes the FSH(Follicle stimulating hormone) and LH (luteinsing hormone). FSH stimulates Sertoli cells to secrete some factors which help in spermiogenesis.
LH acts on the Leydig cells and causes the secretion of testorsterone from the testes.
