LH and FSH are collectively called

  • oxytocin

  • samatotrophins

  • luteotropic

  • gonadotropins

Solution

D.

gonadotropins

Gonadotropins or Gonadotropic hormones are those which stimulate the gonads, ie, testes and ovaries. 

FSH or Follicle Stimulating Hormone stimulates the growth of ovarian follicles and the secretion of oestrogens in the females and spermatogenesis in males.

LH or Luteinizing Hormone stimulates the corpus luteum of the ovary to secrete progesterone in the females. In males, it activates the Leydig's cells of the testis to secrete androgens.

Somatotropins or Somatotropic Hormone or Growth Hormone stimulates growth directly.

Luteotropic Hormones stimulates the corpus luteum of the ovary to secrete progesterone hormone. Also called Mammotropin Hormone (MTH) or Prolactin Hormone (PRL) as it activates growth of breast during pregnancy.

Oxytocin is secreted by posterior lobe of pituitary. It promotes contraction of the uterine muscle and myoepithelial cells of the lactating breast. Also called birth hormone and milk ejecting hormone.
