Background: To evaluate the impact of stimulating the endometrium with high-grade blastocyst culture supernatant (SEHB) perfusion before blastocyst transfer (BT) on implantation rate, pregnancy rate, and pregnancy outcome in ICSI cycles Materials and Methods: Ninety-four infertile couples who were referred to the Valiasr department of Imam Hospital complex between January 2010 and March 2011 en...

Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...
