Step-by-step solution

Spermatogenesis starts at the age of puberty due to significant increase in the secretion of gonadotrophin releasing hormone. The increased levels of GnRH then acts at the anterior pituitary gland and stimulates secretion of two gonadotrophins- leuteinizing hormone and follicle stimulating hormone. LH acts at the Leydig cells and stimulates synthesis and secretion of androgens. FSH acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis
