INTRODUCTION: Few data is available on the natural course of luteinizing hormone (LH) during ovarian stimulation, but it has been suggested that 'oversuppressed' LH could decrease fertility outcomes. Our aim with this study is to evaluate t…

STUDY QUESTION: Does ultra-long downregulation with a GnRH agonist (triptorelin depot) in previously operated patients with endometriosis improve the rate of clinical pregnancy with positive fetal heart beat (CPHB) in the subsequent initiat…

BackgroundEmbryo selection has been based on developmental and morphological characteristics. However, the presence of an important intra-and inter-observer variability of standard scoring system (SSS) has been reported. A computer-assisted…

Endometriosis is associated with a range of pelvic-abdominal pain symptoms and infertility. It is a chronic disease that can have a significant impact on various aspects of women's lives, including their social and sexual relationships, wor…

STUDY QUESTION: Can controlled ovarian stimulation with low-dose human menopausal gonadotrophin (hMG) improve the clinical pregnancy rate when compared with ovarian stimulation with clomiphene citrate (CC) in an intrauterine insemination (I…

BackgroundCell-cell communication and adhesion are essential for the compaction process of early stage embryos. The aim of this study was to develop a non-invasive objective calculation system of embryo compaction in order to test the hypot…

BackgroundAlthough different techniques for sperm immobilization have been described, their value has not been assessed in an adequately powered randomized study. The aim of this study was to compare two types of sperm immobilization method…

BackgroundThe success of in vitro fertilization techniques is defined by multiple factors including embryo culture conditions, related to the composition of the culture medium. In view of the lack of solid scientific data and in view of the…

BACKGROUND: The purpose of this study was to test the hypothesis that menstruation is associated with a higher concentration of endometrial cells in peritoneal fluid(PF) and with increased white and red blood cell concentration in PF when c…

ObjectiveTo evaluate the mechanism of action of recombinant human tumor necrosis factor (TNF)-binding protein-1 by assessing differential expression of messenger RNA (mRNA) for cytokines, matrix metalloproteinases, and growth and adhesion f…

ObjectiveTo examine differential messenger RNA (mRNA) expression of relevant cytokines, metalloproteases, growth and adhesion factors in endometrium and peritoneum from women with endometriosis when compared with women without the disease d…

ObjectiveTo test the hypothesis that the cumulative endometriosis recurrence rate (CERR) after fertility surgery for endometriosis stage III or IV is increased in women exposed to very high E(2) levels during ovarian hyperstimulation (OH) f…

ObjectiveTo test the feasibility of ProteinChip (Ciphergen Biosystems, Inc., Fremont, CA) technology as a proteomic tool in discovering and identifying proteins that are differentially expressed in endometrium, endometriotic tissue, and nor…

Endometriosis is associated with chronic inflammation, including an increased macrophage activity with increased secretion of cytokines, such as tumor necrosis factor (TNF) or TNF superfamily member 2, previously known as TNFalpha. In the p…

BACKGROUND: A key factor in the pathogenesis of endometriosis is the endometrial-peritoneal adhesion. To study the pathogenesis of endometriosis, a quantitative in vitro assay (QIVA) was developed to measure in vitro adhesion between human …

A bstract : Endometriosis is an important gynecological disease, pathologically defined by the ectopic presence of both endometrial glands and stroma, and clinically associated with pelvic pain and infertility. Our current knowledge of the …

Nonparametric linkage analysis is widely used to map susceptibility genes for complex diseases. This paper introduces six nonparametric statistics for measuring marker allele sharing among the affected members of a pedigree. We compare the …

Endometriosis is gynaecological disorder, characterized by the growth of endometrial tissue outside the uterine cavity. It is the most common cause of pelvic pain and occurs in 20-25% of women with infertility. Although Sampson first descri…

There are many arguments to support the hypothesis that there is a causal relationship between the presence of endometriosis and subfertility. These arguments are reviewed in this article and include: (1) an increased prevalence of endometr…

Evidence that endometriosis

Future research in endometriosis must focus on pathogenesis studies in the baboon model, the early interactions between endometrial and peritoneal cells in the pelvic cavity at the time of menstruation, and potential differences between eut…

This article presents an overview of immunological factors and their role in the development of endometriosis, with emphasis on inflammatory cytokines, growth and adhesion factors. Although retrograde menstruation is a common phenomenon amo…

The aim of this review was to assess critically the importance of the frequency, quantity and quality of retrograde menstruation and its relationship to peritoneal inflammation. The basis was the current evidence in women and in baboons sup…

BACKGROUND: Endometrium can adhere to autologous peritoneum. This study was undertaken to determine the effect of the menstrual cycle phase and the presence and stage of endometriosis on in-vitro adhesion of endometrium onto autologous peri…
