Solution

The correct option is D Gonadotropin hormones
FSH and LH are gonadotropin hormones. They are called the gonadotropins as they stimulate gonadal activity. The anterior pituitary (pars distalis) releases following gonadotrophic hormones:
  1. Follicle stimulating hormone (FSH): In males, FSH regulates spermatogenesis (formation of sperms) and in females, FSH stimulates growth and development of ovarian follicles and secretion of estrogen hormone.
  2. Luteinizing hormone (LH): In males, LH is also called ICSH (interstitial cell-stimulating hormone) which stimulates testes to synthesise and secrete androgens (testosterone). It activates Leydig cells of the testes to secrete testosterone. In females, LH stimulates the ovulation of the fully matured Graafian follicles and also maintains the corpus luteum, formed from the remnants of Graafian follicles after ovulation. The corpus luteum secretes progesterone and some estrogen under the action of LH.
