Introduction The mechanisms underlying the pathogenesis of recurrent pregnancy loss (RPL) and effective approaches to treat this disease still remain vague absent. Proteinases ADAMTS family play important roles in embryonic growth development. Our previous study suggest a role ADAMTS13 during pregnancy. Current Study was determine expression human endometrium its association with RPL. Material ...
Clinical and Prognostic Significance of Genetic Factors in Recurrent In-vitro Fertilization Failures
In 1978, a new era has started in the treatment of infertility by the birth of the first baby from a pregnancy achieved by in-vitro fertilization. Following this, healthy pregnancies have been achieved by assisted reproductive techniques such as in-vitro fertilization by an important percentage of the childless couples. Despite all developments in assisted reproductive techniques, pregnancy rat...
the success rate of reproductive treatment methods depends on many different factors. the most important and discussed ones in the literature are maternal age, the causes of infertility, the ovarian response to stimulation, the influence of the male factor and sperm quality, embryo quality and the various uterine pathologies. some couples fail repeatedly after transferring good quality embryos ...

Background: A balanced reciprocal translocation is a structural abnormality, which at least consist of breakage of two non-homologous chromosomes along with pieces exchange and form quadrivalant structure that can produce unbalanced chromosomes during meiosis I and result in a fetus abortion. The aim of the present study is to offer using preimplantation genetic diagnosis (PGD) 24sure array, wh...
Objective. To compare the difference of imprinting status of insulin-like growth factor II (IGF-II) gene in villus between normal embryo development group and abnormal embryo development group and to investigate the relationship between karyotype and the imprinting status of IGF-II gene. Methods. A total of 85 pregnant women with singleton pregnancy were divided into two groups: one with abnorm...
Preimplantation genetic screening (PGS) is widely used to select in vitro-fertilized embryos free of chromosomal abnormalities and to improve the clinical outcome of in vitro fertilization (IVF). A disadvantage of PGS is that it requires biopsy of the preimplantation human embryo, which can limit the clinical applicability of PGS due to the invasiveness and complexity of the process. Here, we p...
This study was conducted in order to investigate the association between the single nucleotide polymorphism (SNP) rs2305957 G/A and recurrent pregnancy loss (RPL) in a group of Palestinian women residing in Gaza strip. A retrospective case-control study was carried out during the period of May to August 2015. A total of 380 females including 190 recurrent pregnancy loss (RPL) patients and 190 c...
The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...
