Answer:
Spermatogenesis begins when the hypothalamus releases a pulse of gonadotrophin-releasing hormone that induces the release of pituitary luteinizing hormone (LH) and follicle stimulating hormone. LH stimulates Leydig interstitial cells to synthesize and secrete testosterone.
Answer:
Gonadotrophin regulating hormone (GnRH) secreted by the hypothalamus stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in male.
FSH enters the testes stimulating the Sertoli cells which help to nourish the sperm cells that the testes produce to begin the process of spermatogenesis.
