background: Several studies have examined the relationship between direct antisperm antibody (ASA) levels in semen and pregnancy rate after advanced assisted reproductive technologies (ARTs) but the results have been inconsistent. The aim of our study was to further evaluate the relationship between ASA and pregnancy after IVF or ICSI by systematic review and meta-analysis. methods: We conducte...

Although somatic cell nuclear transfer (SCNT) cloning is more efficient in cattle than in any other species tested so far, there is a high rate of pregnancy failure that has been linked to structural and functional abnormalities of the placenta. We tested the hypothesis that these changes may originate from disturbed embryo-maternal interactions in the peri-implantation period. Therefore, we ev...

PURPOSE To use binocular integrated visual field (IVF) measures to predict which patients will lose visual function to a level below the legal standard for driving. METHODS Data from patients attending a glaucoma clinic were collected longitudinally. The time from baseline until failure to meet the criteria of the driver's license test was modeled with Cox regression. Visual field status at b...

Background: Protein C deficiency is a rare disease; it could be primary or secondary. Female patients with protein may develop pregnancy-associated thrombosis. The clear association between the and fertility in-vitro fertilization (IVF) results has not been known yet. In our study, we aimed to determine prevalence of in Syrian infertile women assess impact on abortion, recurrent IVF Failure, re...

PGD (preimplantation genetic diagnosis) of aneuploidy for chromosomes X, Y, 13, 18 and 21 was carried out on 196 embryos from 36 infertile patients classified with a poor prognosis due to (i) maternal age, (ii) repeated in-vitro fertilization (IVF) failures and (iii) mosaic karyotype. The percentage of abnormal embryos was comparable in the three groups of patients: maternal age 63%, repeated I...

Embryo implantation depends on both embryo quality and the endometrial environment. Implantation failure has a complex, variable pathophysiology and is detrimental to the outcome of in vitro fertilization (IVF). Thus, patients with multiple implantation failure require an individualized approach to diagnosing and managing treatment options for future IVF cycles. These options should be based on...

Background: Conventional IVF and ICSI are two common techniques to achieve fertilization. IVF has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. The use of ICSI has been expanded in severe male factor and fertilization failure after IVF cycle. In spite of the widespread use of ICSI in patients with non-male factor infertility, ...

In vitro fertilization (IVF) and other assisted reproductive technologies present an enormous hope to couples with fertility difficulties. Assisted reproductive technology is one of the risk factors that can result in anxiety in these couples. Indeed, IVF-treatments cause a stress, for both the woman and her partner. The different stages of the IVF-procedure can affect the emotional life of the...

The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Implantation of the embryo, can only take place in a receptive uterus and inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. Endometrial receptivity can be reduced by morphological and/or molec...
