A prospective cohort study has been performed to find out if the administration of an oxytocin antagonist (Atosiban) at the occasion of embryo transfer has an effect on the pregnancy rate in patients with repeated failure of implantation. A total of 52 women with repeated failure of implantation after IVF/ICSI were included in this study. The ongoing pregnancy rate (OPR) in the total group of p...

Recent evidence shows that through best standard operating procedures, chances of successful pregnancy and live birth delivery rates are less than 50%. Repeated Implantation Failure (RIF) following transfer of one or more numbers of cleavage or blastocyst stage embryos is the main cause of low pregnancy rate in IVF cycles; therefore, finding the causes and modifying treatment protocols to incre...

Assisted reproductive techniques (ART) have become part of the routine care, with a preva‐ lence ranging from 0.1 to 3.9% of all live born children in Europe and an average of 2% in some parts of the USA [1]. Despite the initial dramatic improvements in success rates and significant increments in ART uptake, the live birth rate resulting from these techniques has recently plateaued. Unfortunate...

background: despite numerous developments in the field of assisted reproduction, the implantation rate remains low. among the various reasons of implantation failure, endometrial regularity has an important role. hysteroscopy is an accurate method for evaluating the endometrial characteristics, with the ability to treat uterine pathology. objective: the aim of the present study was to evaluate ...

BACKGROUND Repeated Implantation Failure (RIF) is one of the most intricate obstacles in assisted reproduction. The cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. OBJECTIVE To compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. METHODS After enzymatic digestion o...
