Menstruation Occurs in Response To

Question

Menstruation occurs in response to
A) an LH surge.
B) diminished plasma levels of estrogen and progesterone.
C) elevated plasma levels of hCG.
D) elevation of plasma levels of FSH and LH.

Accepted Answer

Menstruation occurs due to the decrease in plasma levels of estrogen and progesterone, which causes the shedding of the uterine lining. This decrease in hormone levels is a result of the end of the menstrual cycle and not caused by any external hormonal influences such as an LH surge or elevated levels of hCG. While FSH and LH play a role in the menstrual cycle, they are not the primary drivers of menstruation.
