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.
