Question

GnRH of hypothalamus stimulates secretion of

• A. Aldosterone from adrenals
• B. ADH from posterior pituitary
• C. FSH and LH from anterior pituitary
• D. Thyroxine from thyroid

Answer 1

The correct option is C FSH and LH from anterior pituitary

GnRH (Gonadotropin releasing hormone) is secreted from hypothalamus. It stimulates the secretion of FSH and LH from anterior lobe of pituitary gland. FSH (Follicle stimulating hormone) stimulates the growth of ovarian follicles in females and seminiferous tubules in males. This hormone also promotes spermatogenesis in males i.e. the process of formation of sperms from the germ cells. LH (Luteinizing hormone) stimulates growth of ovarian follicles in females. In males this hormone is called interstitial cell stimulating hormone or ICSH and affects the Leydig cells of testes.

So, the correct answer is 'FSH and LH from anterior pituitary'.
