The anterior pituitary gonadotropins FSH and LH exert their actions upon___________________?
Show answer Hide answer
Answer: C. Both Testis and ovaries
Explanation
FSH and LH are pituitary gonadotropic hormones that regulate reproductive organ function. They stimulate target tissues in both male and female gonads successfully. Option C is correct because both testes and ovaries respond to these hormones. Gonadotropins are released by anterior pituitary gonadotroph cells under hypothalamic control. In males, LH stimulates testosterone production while FSH supports spermatogenesis. In females, LH triggers ovulation while FSH promotes ovarian follicle maturation.
Fertility treatments utilize exogenous gonadotropins to stimulate gamete production in patients. Endocrine disorders affecting the pituitary gland can disrupt function in both sexes. Measuring gonadotropin levels helps diagnose primary versus secondary hypogonadism. Option A is incorrect because gonadotropins act on both male and female gonads. Option B is incorrect because FSH and LH also stimulate testicular function in males. The adrenal cortex responds to ACTH rather than anterior pituitary gonadotropins.
