BACKGROUND: The Fifth Evian Annual Reproduction (EVAR) Workshop Meeting discussed knowledge regarding contemporary genetics in female reproduction. METHODS: Specialist reproductive medicine clinicians and geneticists delivered presentation…

BACKGROUND: There is a need for a reliable marker of endometriosis, especially in early stages of peritoneal disease during which imaging is not effective. The use of serum interleukin (IL)-6 as a marker is controversial. To readdress the m…

The leptin system has been implicated in reproductive function, acting at endocrine and paracrine levels. Recently, deregulation of this gene family has been linked to endometrial changes caused by endometriosis. In the present study, we co…

In spite of a great deal of effort over many decades, the mechanisms that lead to infertility in women with endometriosis remain unknown. Moreover, controversial results in the literature add even more difficulties in the understanding of t…

Several analyses in our infertility (IVF) and oocyte donation programs were carried out to gain clinical knowledge of the factors involved in the etiology of endometriosis-associated infertility. We first compared the IVF outcomes in women …

ObjectiveTo assess endometrial receptivity in terms of pinopode expression in women with endometriosis.DesignProspective, observational study.SettingOocyte donation program at the Instituto Valenciano de Infertilidad.Patient(s)Twelve women …

ObjectiveTo investigate the production and secretion of interleukin (IL)-6 and vascular endothelial growth factor (VEGF) mRNA and protein by granulosa luteal cells (GCs) in vivo and in vitro in women with and without endometriosis.DesignPro…

The use of in-vitro fertilization (IVF) as a therapeutic tool in patients with endometriosis has provided information about the disease and, in particular, aspects of the reproductive process in humans, particularly folliculogenesis, fertil…

ObjectiveTo evaluate the impact of severe endometriosis on IVF-ET outcome in women receiving oocytes from the-same donor.DesignA matched case-control study.SettingOocyte donation program at the Instituto Valenciano de Infertilidad.Patient(s…

Several retrospective analyses of IVF and oocyte donation programmes, performed to gain clinical knowledge of the factors implicated in the aetiology of endometriosis-associated infertility, have demonstrated that the quality of the embryo …

Chemokines are a new family of cytokines specialised in attracting leukocytes, acting in physiological conditions and in pathological processes. A wide variety of cell types in response to exogenous irritants or endogenous mediators of the …

ObjectiveTo assess the endocrine, paracrine, and autocrine milieu in patients with endometriosis on the basis of the measurement of several cytokines in serum and follicular fluid (FF) and in vitro culture of granulosa luteal cells.DesignCa…

OBJECTIVE: To assess the endocrine milieu in follicles of stimulated cycles comparing women with and without endometriosis. Steroids were measured in follicular fluid (FF) and in in vitro culture of granulosa-luteal cells, and this status w…

To assess the impact of endometriosis on intracytoplasmic sperm injection (ICSI) outcome, we have retrospectively evaluated 980 ICSI cycles, comparing the results of women with and without endometriosis. A total of 101 cycles was identified…

ObjectiveTo determine an optimal insemination technique in patients undergoing IVF after failed IUI and the role of intracytoplasmic sperm injection (ICSI) in such cases.DesignProspective, randomized study in couples with unexplained infert…

Several retrospective analyses of our in-vitro fertilization (IVF) and oocyte donation programmes have been carried out in an attempt to gain clinical knowledge of the factors implied in the aetiology of endometriosis-associated infertility…

A retrospective analysis of our in-vitro fertilization (IVF) and oocyte donation programmes was carried out in order to gain clinical knowledge of the factors involved in the aetiology of the endometriosis-associated infertility. Comparison…

ObjectiveTo investigate the messenger ribonucleic acid (mRNA) expression of interleukin-1 (IL-1) type I receptor in the endometrial tissue of normal patients during the menstrual cycle.DesignProspective longitudinal study.SettingDepartment …

ObjectiveTo investigate the effect of short-term glucocorticoid administration on embryotoxicity of sera from infertile patients with mild to moderate endometriosis.DesignProspective longitudinal study.Setting, patientsEight infertile patie…
