which of the following hormone induces spermatogenesis?
GnRH
ACTH
ADH
all of the above
Spermatogenesis begins at puberty when the GnRH hormones level rises and stimulates anterior pituitary to secrete two gonadotrophin hormones LH and FSH, thereby inducing spermatogenesis.
ACTH is hormone concerned with adrenal system and not with reproductive system.
ADH is anti-diuretic hormone that plays vital role in maintaining water - electrolyte balance, and not related to the process of spermatogenesis.
Hence option A is correct.
