BACKGROUND Previous studies examining experiences of infertility focused mainly on the aspect of loss but neglected the possible gains realized through surviving the experience of infertility. The success rate of IVF remains relatively low, and we used the strengths perspective to examine adjustment after unsuccessful treatment. This study aims to provide an in-depth description of the gains pe...

Accumulation of oviductal fluid in the ampullar lumen as a result of occlusion of the infundibulum is referred to as hydrosalpinx. A low pregnancy rate (10%) after in-vitro fertilization (IVF) in hydrosalpinx patients and a relatively high incidence (50%) of abortions during the first trimester suggested that leakage of this fluid into the uterine cavity may exert a cytotoxic effect on the deve...

Embryo transfer (ET) is universally recognized as the final and most critical stage in an in vitro fertilization (IVF) outcome (Neithardt et al., 2005; Ghazzawi et al., 1999). The majority of couples (approximately 80%) who undergo IVF reach the embryo transfer stage, yet few pregnancies occur (Mansour & Aboulghar, 2002; Adamson et al., 2006). Although embryo genetic abnormalities (Munne et al....

BACKGROUND Hexachlorobenzene (HCB), dichlorodiphenyltrichloroethane (DDT), and dichlorodiphenyldichloroethylene (DDE) are persistent chlorinated pesticides with endocrine activity that may adversely affect the early stages of human reproduction. OBJECTIVE Our goal was to determine the association of serum levels of HCB, DDT, and DDE with implantation failure, chemical pregnancy, and spontaneo...

Background Implantation failure is the most important cause of recurrent in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) failure. Several reports suggest that intercourse during the peritransfer period might improve pregnancy rates. This study is designed to determine whether intercourse during the peritransfer period will improve pregnancy and implantation rates in patients...

As numerical and structural defects in chromosomes are an inevitable consequence of IVF, Pre-implantation genetic diagnosis and screening (PGD/PGS) methods are used for detecting abnormalities in embryos before implantation to the uterus to increase the successful rate of IVF. Pre-implantation genetic diagnosis and screening approaches can be achieved by different techniques such as NGS, CGH an...

We report three cases of effective management of infertility in women with a history of repeated unsuccessful IVF attempts, who have developed antibodies to hCG. A novel approach to conservative treatment of immunologic reproductive failure, suggested for selected patients, included membrane plasmapheresis, combined prednisolone, and intravenous immunoglobulin therapy. No adverse side effects w...

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 appropriate management for male partners of couples with recurrent pregnancy loss (RPL) or recurrent implantation failure during in vitro fertilization (IVF) remains unclear. In particular, men with normal semen parameters are often ignored because the “bulk semen parameters” appear normal [1]. Despite normal semen parameters, male partners in couples with RPL or recurrent implantation fail...

Despite the advent of ICSI, cases of total fertilization failure (TFF) often lead to cycle cancellation with limited diagnostic and therapeutic strategies currently available. We report on the case of an infertile couple who failed to conceive after repeated IVF and ICSI. Sperm of the husband were morphologically normal and passed a functional test assessing their ability to activate mouse oocy...
