proliferates under the influence of estrogen. However, after ovulation, luteal progesterone changes the proliferative pattern to a secretory pattern that includes decidualization of endometrial stromal cells, which provides the nutritive and immune

indicate that the pathways utilized by FSH in estrogen synthesis are not completely the same as those in FSH-induced progesterone production ( Zeleznik et al. 2003 ). In the classical model, FSH binds to its cognate G-protein-coupled receptor and then
