The predictive value of serial serum estradiol and serial endometrial volume on endometrial receptivity on assisted reproductive technology cycles

Abstract Background Diagnosis of endometrial receptivity is still unclear and conflicting. Despite advances in embryo development during assisted reproductive technologies (ART) cycles, the intricate process implantation matter for debate research. Materials methods Prospective case control 169 subjects ovarian controlled stimulation ART. Endometrial assessment to predict clinical pregnancy with serial continuous biochemical (serum estradiol) biophysical (endometrial volume adjusted volume) parameters were used. Both compared between negative positive outcome terms pregnancy. Results No statistical difference was noted two groups demographics ART procedures scores. Serum estradiol significantly higher group from day 8 after stimulation. as soon 6 Conclusions Continuous serum 3D volumes may reflect changes provide a useful real time tool clinicians predicting receptivity.
