Step-by-step solution

Gonadotropin releasing hormone (GnRH) is secreted by the hypothalamus and acts on the anterior pituitary gland to stimulate the secretion of LH and FSH. Luteinising hormone (LH) acts on the Leydig cells (interstitial cells) and stimulates the synthesis and secretion of androgens. Follicle stimulating hormone (FSH) acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis. Androgens, in turn, stimulate the process of spermatogenesis. Therefore, the correct match i
