Question

anonymous · Answer

menstruation


progesterone is needed to maintain the endometrium, its absence leads to its shedding and resultant phase of menstuation.

anonymous · Answer

But doesn't it also fall during menopause?
and in lactation too?

I have a feeling the question is wrong and it should actually be "Progesterone level rises during" and then it would be gestation. Correct me if I am wrong please.

yes, levels fall during lactation, menopause, and menstruation
