Question

Spermatogenesis in mammals is controlled by

• A. Follicle stimulating hormone
• B. L.H.
• C. Follicle stimulating hormone and prolactin
• D. Growth hormone and prolactin

Answer 1

Answer: (A)

Follicle stimulating hormone

• FSH (Follicle stimulating hormone) is secreted from the anterior part of pituitary gland. It 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.
• Luteinizing hormone or LH 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.
• Prolactin, also known as lactogenic hormone is produced by the pituitary gland. This hormones stimulates the production of milk in mammary glands during pregnancy.
• Growth hormone is secreted from anterior part of pituitary gland and stimulates body growth and metabolism of carbohydrates, fats and proteins.

Hence, spermatogenesis in mammals is controlled by FSH.

So, the correct is 'F.S.H. (Follicle stimulating hormone)'.
