During menstruation, a drop in both estrogen and progesterone causes the corpus luteum to atrophy, right?

correct

 

[jefff]

really? i thought it was the lack of fertilization and therefore lack of hCG

 

[jefff]

from my understanding:

corpus luteum provides a portion of the progesterone and estrogen which maintain the endometrium

when the egg isnt fertilized and hCG isnt produced (hCG is supposed to keep the corpus luteum 'alive' long enough until the placenta can take over the estrogen/progesterone production) then:

corpus luteum ---lack of hCG---> corpus albicans

therefore drop in estrogen and progesterone
therefore drop in endometrial maintenance
therefore sloughing
therefore menses commences
therefore messy panties

if someone can please help confirm and/or clarify this
