In the present study we evaluated the effects of physiological and supra-physiological variation of estrogen levels on scopolamine-induced amnesia in gonadally intact female r...
Background: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Metformin which is effectively used for the treatment of anovulatory PCOS improves pregnancy rate and endometrial receptivity and reduces the risk of miscarriage. The aim of this study was to evaluate the effects of metformin on the endometrium, the number of fetuses and hormonal levels ...
Introduction: Sexhormones are one of most important factors in difference of learning and memory between tow sexes (male & female). High concentration of estrogen and androgen receptors and mechanism of testosterone and estrogen production in learning and memory center, especially in hippocampus show the role of this receptors, sexhormons and P450 enzymes in spatial memory. Consequently, in thi...

Background: The aim of this prospective randomized clinical trial was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in FET cycles, that is, oral estradiol and 17 β-estradiol transdermal patch. Materials and Methods: A total number of 90 patients were scheduled for FET. In the study group (n=45), 17-B estradi...
