Apoptosis is a physiologic process that deletes unwanted cells without inducing an inflammatory reaction. Survival of endometriotic implants is associated with decreased apoptosis and an inflammatory environment. The most widely accepted th…

Endometriosis is a common gynecologic disorder characterized by the presence of endometrial tissue outside the uterine cavity. Although no single theory can explain all cases of endometriosis, the most commonly accepted theory is Sampson's …

PROBLEM: Accumulating data suggests that aberrant immune responses during retrograde menstruation may be involved in the development of endometriosis. METHOD OF STUDY: The role of immunology in the etiology of endometriosis is reviewed and …

BACKGROUND: Interleukin (IL)-15 is a novel cytokine with immunoregulatory and angiogenic properties. We compared IL-15 levels in the peritoneal fluid (PF) of women with and without endometriosis. METHODS: PF samples were obtained from 55 wo…

PROBLEM: Pregnancy-associated plasma protein-A (PAPP-A) belongs to a group of glycoproteins isolated from extracts of human placenta. Healthy ovarian and uterine tissues are also known to express PAPP-A. We hypothesized that PAPP-A levels m…

Endometriosis is a common gynecologic disorder characterized by the presence of endometrial tissue outside the uterine cavity. Various theories have been put forth to explain the mechanisms for the development of this disease. Although no s…

A 36-year-old woman with a 20-year history of endometriosis-associated pelvic pain was a unique case from a total of 700 patients with endometriosis recently evaluated at Yale University. Her previous treatments included 11 surgical procedu…

ObjectiveTo evaluate soluble Fas ligand concentrations in serum and peritoneal fluid from women with endometriosis and from fertile controls without endometriosis, and to study levels of soluble Fas ligand in conditioned media of cultured e…

Interaction between endometrial stromal cells and extracellular matrix (ECM) components has a crucial role in the development of endometriosis. Endometrial stromal cells attach to the mesothelial surface of peritoneum by means of integrins …

Endometriosis, defined by the presence of viable endometrial tissue outside the uterine cavity, is among the most common gynecologic disorders affecting women of reproductive age. Endometriosis is associated with an inflammatory peritoneal …

The association between endometriosis and infertility is complex. Nevertheless, in the absence of tubal distortion considerable evidence suggests four principle factors likely to contribute to subfertility. These include impaired folliculog…

ObjectiveTo report a rare case of a patient with catamenial hemoptysis, secondary infertility, and endometriosis associated with a unicornuate uterus and noncommunicating rudimentary horn.DesignCase report.SettingUniversity hospital.Patient…

PROBLEM: Chemokines are increasingly recognized as important regulators of uterine function. METHODS OF STUDY: The following is a review of uterine chemokines, especially monocyte chemotactic protein (MCP)-1, interleukin (IL)-8, and regulat…

ObjectiveThe level of monocyte chemotactic protein-1 (MCP-1), a potent chemoattractant for monocytes, is fivefold higher in myometrium than in leiomyoma. We have previously shown that myometrium from women using GnRH agonists (GnRH-a) expre…

The preponderance of recent data suggests that endometriosis does not adversely affect in-vitro fertilization pregnancy rates. However, many studies demonstrate impaired oocyte quality, decreased fertilization, and compromised implantation …

Clinical observations indicate that an implantation defect occurs in women with endometriosis. Despite intense research, the role of alterations in endometrial receptivity and the peritoneal fluid microenvironment in the derangement of impl…
