Q7. Name the hormones involved in regulation of spermatogenesis.
Spermatogenesis initiated due to an increase in the secretion of gonadotropin-releasing hormone by the hypothalamus. Increase in GnRH act on anterior pituitary and stimulate secretion of two gonadotropins, LH (luteinizing hormone) and FSH (follicular stimulating hormone). Among these, LH acts on Leydig cells and stimulates them to secrete androgens whereas FSH acts on Sertoli cells and stimulates the secretion of some factors which help in spermiogenesis
