Low power magnfication of the endometrium in the intestinal . (Adenofibromyoma cysticum sarcomatodes carcinomatosum). Though retrograde menstruation explains the physical displacement of endometrial fragments into the peritoneal cavity, additional steps are necessary for the development of endometriotic implants. Primarily these locations are found to be the pelvic peritoneum, ovaries, and rectovaginal septum. The new PMC design is here! In addition to decreased apoptosis, enhanced proliferation may confer a selective survival advantage to endometrium of women predisposed to endometriosis (32). Peritoneal endometriosis due to menstrual dissemination of endometrial tissue into the peritoneal cavity.

As far as the embryo is concerned, poor quality embryos or sperm along with parental chromosomal anomalies are the main causes of an embryo failing to implant . MMP-1 is expressed focally in red peritoneal lesions regardless of the menstrual phase, but not in black peritoneal lesions (97). Other cytokines or chemokines found to be increased in the peritoneal fluid of patients with endometriosis include macrophage migration inhibitory factor (79), TNF- (80), IL-1, IL-6 (81), IL-8, regulated on activation, normal T expressed and secreted (RANTES), and monocyte chemoattractant protein-1 (MCP-1) (82). . Competing interests: We have read and understood BMJ policy on declaration of interests and declare the following interests: AWHs institution (University of Edinburgh) has received payment for consultancy and grant funding from Roche Diagnostics to assist in the early development of a possible blood diagnostic biomarker for endometriosis. The etiology of RIF can be attributed to dysfunction of the two major players of implantation, namely the embryo and the endometrium. Yang Y, Degranpre P, Kharfi A, Akoum A. Growth factors may play a fundamental role in stimulating ectopic endometrial growth and differentiation.

The prevalence as well as the pathophysiology of this is unknown. Red vesicular lesions with focal hemorrhage observed on the posterior aspect of the broad ligament. Even subtle compromise of antegrade menstruation may predispose to endometriosis, as evidenced by the higher prevalence of endometriosis in women with a uterine septum (25) and cervical stenosis (26). Intrinsic to these theories are inciting factors and genetic susceptibilities whose roles are beginning to be delineated, though insufficiently established to confirm cause and effect and subsequent development of endometriosis. The peritoneal microenvironment in the setting of endometriosis is notably rich in prostaglandins, and these mediators likely play a central role in disease pathophysiology as well as clinical sequelae of pain and infertility.
