Questions and Answers

What is the main reason for the irregular function leading to menopause?

  • Hypothalamus losing its ability to respond to the gonadotropins.
  • Anterior pituitary secreting decreased amounts of gonadotropins.
  • Ovarian follicles and eggs disappearing through atresia. (correct)
  • Decreased plasma estrogen and inhibin exerting positive feedback on gonadotropin secretion.

What happens to the ovaries during menopause?

  • They increase their response to gonadotropins.
  • They undergo hypertrophy.
  • They stop secreting estrogen and inhibin.
  • They lose their ability to produce eggs. (correct)

What primarily causes menopause?

  • Ovarian failure due to loss of ovarian follicles and eggs. (correct)
  • High levels of estrogen and inhibin in the blood.
  • Overactive hypothalamus and anterior pituitary.
  • Decreased secretion of gonadotropins.
