background: repeated implantation failure (rif) is defined as pregnancy failure after two to six times with at least ten high grade embryo transfer to uterus. a variety of causes have been anticipated for rif, including anatomical, autoimmune, genetics, endocrine and thrombotic anomalies. factors responsible for rif have important implication regarding treatment however in many couples a perfec...

objective: repeated implantation failure (rif) is a condition in which the embryos implantation decreases in the endometrium. so, our aim was to evaluate the effect of local endometrial injury on embryo transfer results. materials and methods: in this simple randomized clinical trial (rct), a total of 120 patients were selected. the participants were less than 40 years old, and they are in thei...

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...

The objective: to determine the effectiveness of intrauterine administration granulocyte colony-stimulating factor depending on endometrium immune phenotype in patients with repeated implantation failures embryo transfer programs.Material and methods. Endometrial biopsy during window an artificial cycle before (in some patients) after (G-CSF) was performed 42 gestational carriers (20 women) as ...

The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Clinicians who treated unsuccessful couples often face a challenge. The probable causes of repeated IVF failures classified as: reduced endometrial receptivity, embryonic defects or multifactorial causes. Intrauterine and endometrial integrity...

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 The purpose of this study was to compare laboratory and clinical outcomes of intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (ICSI) in couples with repeated implantation failures. METHODS A total of 200 couples with at least two prior unsuccessful ICSI cycles were enrolled: 100 couples were submitted to IMSI and 100...
