Introduction: The ovarian stimulators have a crucial role in steriodogenesis, follicular development, oocyte maturation and embryo maintenance by activating some genes in ovarian follicles. As, one of the most important cellular and molecular mechanisms involved in successful fertilization is the expression of sperm receptor binding protein or ZP3 in zona Pellucida, therefore our attempts have been made to delineate the effects of combined Estradiol and eCG on ZP<su...
