BACKGROUND Hydrosalpinx are associated with infertility, due to reduced rates of implantation and increased abortion rates. The aims of this study were to investigate the expression of cystic fibrosis transmembrane conductance regulator (CFTR), nuclear factor kappa B (NF KappaB) and mucin-1 (MUC-1), and analyze the correlation between the expression of CFTR and NF KappaB or MUC1, in the endomet...
Objective: This study aims to investigate the effects of a new surgical procedure to treat hydrosalpinx prior to in vitro fertilization and embryo transfer (IVF-ET). Methods: Infertile females receiving treatment for hydrosalpinx (n=633) were divided into one treated group and two comparison groups. The treated group comprised patients received pretreatment with core-pulling salpingectomy (n=10...
Recent studies have suggested that the hydrosalpinx has a negative effect on pregnancy outcome, with markedly diminished implantation and increased early pregnancy loss. Fluid from the hydrosalpinx may leak into and accumulate in the uterine cavity. It is not clear, however if this creates a hostile local environment in the uterus for embryo implantation or exerts a direct embryotoxic effect. T...
Recent reports suggest a deleterious effect of hydrosalpinges on pregnancy outcome for in-vitro fertilization (IVF) and improvement following surgical treatment. We compared the effect of hydrosalpinx on pregnancy outcome in 286 patients having 348 IVF cycles and followed the development of untransferred embryos for 7 days to determine if hydrosalpinges affect oocyte quality or embryo developme...
The negative impact of hydrosalpinx on IVF outcome is well recognized but some reports indicate that tubal infertility with hydrosalpinx is a heterogeneous entity and may have different effects on the outcome. The embryotoxic effects of hydrosalpinx fluid (HF) have been documented in mouse but not human embryos. This study examined the effects of HF on sperm motility and survival after various ...
A retrospective analysis of clinical and laboratory data was made of all in-vitro fertilization (IVF) patients with tubal pathology who had their first ever embryo transfer cycle between January 1st, 1992 and September 1st, 1996. The aim of the study was to determine the effect of the presence of a hydrosalpinx, whether or not visible by ultrasound, on pregnancy, multiple pregnancy and implanta...
I read with interest the manuscript by De Wit et al. (1998) which sheds a new light on the hotly debated subject of the adverse role that hydrosalpinx plays in in-vitro fertilization (IVF). The authors need to be congratulated for successfully showing that women with hydrosalpinges are indeed a heterogeneous group: when hydrosalpinges are clearly visualized by ultrasound, the implantation rate ...
Hydrosalpinges have been associated with poor in-vitro fertilization (IVF) outcome in some, but not all, studies, perhaps through endometrial effects. To determine whether hydrosalpinges affect IVF outcome via endometrial factors alone, we analysed the results of recipients of donor oocytes with hydrosalpinges, thereby controlling for confounding variables, while isolating the intrauterine envi...
It has been previously reported that although inducible nitric oxide synthase (iNOS) gene knockout (NOS2(-/-)) mice resolve Chlamydia trachomatis genital infection, the production of reactive nitrogen species (RNS) via iNOS protects a significant proportion of mice from hydrosalpinx formation and infertility. We now report that higher in vivo RNS production correlates with mouse strain-related ...
