does progesterone inhibit FSH and LH
or just FSH
or Just LH
when preventing ovulation

destroyer q103 says "progesterone will inhibit FSH release and thereby prevent ovulation"

achiever q39 syas "eleveate amount of progesterones inhibits release of LH from anterior pit, rendering ovulation through LHs surge unlikely to happen"

which is right?

it all starts off in the blood when you dont have sufficient levels of estrogen or progesterone the hypothalamus will be triggered via negative feedback to produce GnRH and stimulate the anterior pituitary to produce FSH....so if you have high levels of progesterone the whole cycle wont even happen...the receptors in the circulatory system will not stimulate the hypothalamus telling it that there are low levels and therefore trigger FSH release...which in turn triggers estrogen release from the follicle and therefore causes a surge in LH....

but again this wont happen if you have high levels of either progesterone or estrogen in the blood...
