Although peritoneal endometriosis was recognized in 1860, its pathogenesis still remains unclear. Several theories attempt to explain the pathogenesis of this condition. From these, the implantation theory maintains that peritoneal endometriosis is the result of implantation and subsequent growth of retrogradely shed viable endometrial cells. Based on a second theory, the peritoneal mesothelium...

STUDY QUESTION Does the phytochemical compound resveratrol inhibit vascularization of endometriotic lesions? SUMMARY ANSWER Resveratrol suppresses the development of new microvessels in endometriotic lesions by inhibiting endothelial cell proliferation. WHAT IS KNOWN ALREADY Establishment and progression of endometriosis is crucially dependent on angiogenesis. Resveratrol is a pleiotropic a...

BACKGROUND Implantation of a retrogradely-shed endometrium during menstruation requires an adequate blood supply. The endometrium has angiogenic potential, and endometriotic lesions grow in areas with a rich vascularization, suggesting that angiogenesis is a prerequisite for endometriosis development. Targeting vascular endothelial growth factor (VEGF) leads to an inhibition of endometriosis. D...

A growing body of evidence suggests that endometriosis modulates the microenvironment of peritoneal cavity. Therefore, in this study, we compared the protein profile of peritoneal fluids from normal fertile women with those from patients with infertility, and patients with mild to severe endometriosis. Two-dimensional gel electrophoresis of peritoneal fluids from normal subjects exhibited a dis...

Accumulated evidence implicates immunological alterations in endometriosis. The purpose of this study was to look for variations in antibodies to distinct antigens in peritoneal fluid of women with and without endometriosis. Peritoneal fluid was aspirated from 17 women undergoing laparoscopy for tubal ligation and 37 patients complaining of symptoms of pain and/or infertility. Peritoneal fluid ...

OBJECTIVE To determine whether peritoneal fluid from women with endometriosis contributes to infertility by impairing sperm motion and functional characteristics. METHODS Women with endometriosis (n = 20) underwent laparoscopy for infertility or pelvic pain. Patients undergoing tubal ligation served as controls (n = 14). Peritoneal fluid was aspirated from women with endometriosis, or from wo...

Abdomino-pelvic adhesions arise from infection, endometriosis, or peritoneal injury during surgery, and represent a significant source of morbidity in women of reproductive age. Monocyte chemotactic protein-1 (MCP-1) plays a role in the chemotaxis of mononuclear cells and fibroblasts in a murine wound repair model. To evaluate the role of MCP-1 in intraperitoneal adhesion formation, we investig...

Background: Endometriosis is known as one of the most common disease in women of reproductive age. Due to importance role of vascular endothelial growth factor (VEGF) in neo-vascularization for the implantation of endometrial cell and different reported results for VEGF level in the serum and peritoneal fluid (PF) in endometriosis patients, this study was designed to determine the serum and PF ...

BACKGROUND The aim of this study was to evaluate the leptin levels in the serum and peritoneal fluid (PF) and the protein expression in three different peritoneal ectopic implants in patients who underwent surgery for deep infiltrating endometriosis. METHODS All patients had been treated at the Department of Gynecology of the Pedro Ernesto University Hospital, Rio de Janeiro. The study group ...

Background: Endometriosis is a chronic inflammatory disease with the growth of endometrial cells out of uterus and in the peritoneal cavity. T cell subsets participate in the establishment and progress of the disease by producing different cytokines. Objective: To investigate a group of cytokines related to Th1/Th2/Th17/Treg subsets within both peripheral blood...
