Question

Gonadotropic hormones are

• A. Testosterone and androsterone
• B. Estrogen and progesterone
• C. LH and FSH
• D. Prolactin and luteotropin

Answer 1

The correct option is C LH and FSH

A. Testosterone is the male sex hormone secreted from Leydig cells in testis and stimulates the development of secondary sexual characteristics in males.

Androsterone is the inactive male sex hormone produced from the metabolism of testosterone. This hormone is present in urine.

B. Estrogen is the female sex hormone secreted from ovarian follicles and stimulate the development of female secondary sex organs.

Progesterone is a steroid female sex hormone which is also known as pregnancy hormone. It maintains the inner lining of uterus which aids in implantation of embryo in the uterus.

C. 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.

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.

D. Prolactin, also known as lactogenic hormone is produced by the pituitary gland. This hormones stimulates the production of milk in mammary glands during pregnancy.

Luteotropin is another name for prolactin.

Gonadotropic hormones are LH and FSH because they are important for reproduction.

So, the correct answer is 'LH and FSH'.
