Question
Spermatogenesis in human males is a hormone regulated process. Justify.
✓
Answer
Hormonal control of spermatogenesis:Spermatogenesis is initiated at the age of puberty by the gonadotropin releasing hormone (GnRH) secreted by the hypothalamus.
The increased levels of GnRH stimulate the anterior pituitary which then secretes the FSH (follicle stimulating hormone) and LH (luteinising hormone). FSH stimulates Sertoli cells to secrete some factors which help in spermiogenesis.
LH acts on the Leydig cells and causes the secretion of testosterone from the testes.
