In vivo treatment with GnRH or with GnRH agonistic analog (AG), but not with GnRH antagonistic analog (ANT), depleted the LH stores of the rat pituitary gland. This depletion was potentiated by oestradiol. Oestradiol augmented the in vitro LH response of the pituitary gland to GnRH. This augmenting effect of oestradiol became smaller with increasing rates of in vivo administration of GnRH or AG, but not with ANT. With respect to both depletion of the LH stores and suppression of the augmenting effect of oestradiol, AG ist about 20 times as potent as GnRH.
