Endometriosis is one of the most frequently encountered benign diseases in gynecology. Complete resolution of endometriosis is not yet possible, but therapy has essentially three main objectives: (1) to preserve and improve fertility, (2) t…

BACKGROUND: Steroid sulfatase (STS) is involved in estrogen biosynthesis and expressed in eutopic and ectopic endometrium of disease-free and endometriosis patients. The present study was designed to investigate its role in endometriosis de…

Endometriosis is an estrogen-dependent disorder. Treatment with hormonal therapy suppresses estrogen and leads to regression of lesions. However, hormonal therapy is associated with significant morbidity, adverse effects, and recurrence of …

Endometriosis is a chronic pelvic inflammatory process. Local inflammation is known to play a role in pain and infertility associated with the disease, and may be extensively involved in molecular and cellular processes leading to endometri…

OBJECTIVE: To determinethe prevalence of spontaneous endometriosis andthe incidence of induced endometriosis after endocervical canal resection in baboons. DESIGN: Induction and follow-up of endometriosis in baboons, which is one of the pr…

Menometrorrhagia, defined as excessive and prolonged uterine bleeding occurring at irregular and/or frequent intervals, occurs in up to 24% of women aged 40-50 years. There are a wide range of causes of menometrorrhagia, although histologic…

PURPOSE OF REVIEW: To evaluate different surgical options for the treatment of endometriomas. A heated debate is currently under way between advocates of excisional surgery and the ablative approach. With papers increasingly focusing on ova…

Peritoneal endometriosis is a chronic inflammatory disease characterized by increased numbers of peritoneal macrophages and their secreted products. Inflammation plays a major role in pain and infertility associated with endometriosis, but …

Peritoneal, ovarian, and rectovaginal endometriosis are three different entities. Peritoneal endometriosis can be explained by the transplantation theory. Coelomic metaplasia of invaginated epithelial inclusions may be responsible for the d…

Why we need international agreement on terms and definitions to assess clinical outcome after endometriosis surgery

In this study, we developed an original and reproducible quantitative in vitro model of endometrial cell adhesion to peritoneal mesothelial cells in order to better assess the impact of pro-inflammatory cytokines on early-stage endometriosi…

BACKGROUND: The debate continues between advocates of the shaving technique and supporters of bowel resection in case of deep endometriosis with rectal muscularis involvement, despite little evidence for better improvement with bowel resect…

OBJECTIVE: To compare expression of homeobox A (HOXA) genes involved in the differentiation of the female reproductive tract in deep endometriotic nodules and peritoneal lesions. DESIGN: Prospective experimental study. SETTING: Academic g…

To study the effect of endometriosis on follicular rupture, endometrial tissue was autografted to New Zealand White rabbits. Endometrium was surgically implanted into the peritoneal cavity or into the rectus muscle. Human chorionic gonadotr…

OBJECTIVE: To evaluate the role of nuclear factor-κB (NF-κB) in the pathogenesis of endometriosis. DESIGN: A literature search was conducted in PubMed to identify all relevant citations. RESULT(S): Our findings highlight the important rol…

OBJECTIVE: To describe and evaluate a new technique of laparoscopic treatment of endometriomas that combines excisional and ablative surgery. DESIGN: Descriptive and prospective study. SETTING: Gynecology research unit in a university hos…

Data on the presence of an ovulation ostium and the volume and the concentrations of estradiol (17 beta-estradiol) and progesterone In women with endometriosis (n = 80) and women with luteinized unruptured follicle (LUF) syndrome (n = 32) a…

BACKGROUND: Aromatase has been reported to be involved in estrogen biosynthesis and expressed in eutopic and ectopic endometrium of endometriosis patients. The objective of the present study was to investigate its expression and localizatio…

BACKGROUND/AIMS: Endometriosis is known to be an estrogen-dependent disease. However, only a few studies have analyzed the effect of estrogen treatment in mice xenotransplanted with human endometrium. The objective of this study was to adap…

BACKGROUND: Increased peritoneal eicosanoid concentrations have been reported in endometriosis patients and might be important in disease-associated pain and inflammation. Here, we evaluated the expression of key biosynthetic and catabolic …

PurposeEctopic endometrial tissue is biochemically and functionally distinct from eutopic endometrium, including differences in receptivity to steroids and invasive potential. For this reason, using ectopic endometrial tissue to induce endo…
