BackgroundLocal pro-inflammatory environment and enhanced cell survival contribute to the endometriosis development. A serine/threonine kinase p38 mitogen-activated protein kinase (MAPK) mediates intracellular signaling of cytokine producti…

Statins are potent inhibitors of the endogenous mevalonate pathway. Besides inhibiting cholesterol biosynthesis, statins may also demonstrate anti-inflammatory properties. Inflammation is implicated in the attachment and invasion of endomet…

HOX genes impart segmental identity to the developing reproductive tract. HOX gene expression in adults is found in the endometrium with peak expression levels occuring in the mid- and late secretory phase of the menstrual cycle. HOXA10 is …

ObjectiveThe aim was to determine the number and the grade of oocyte-corona-cumulus complex (OCCC) and the most viable embryos for transfer in women with endometriosis compared to those with tubal factor infertility.Study methodsPatients un…

PURPOSE: Women with endometriosis have been reported to be at increased risk of developing non-Hodgkin's lymphoma (NHL). The purpose of this article was to investigate the familial risk of NHL in women with endometriosis. We report on 10 ca…

The aim of this study is to report three cases of patients with endometriosis and infertility, and associated with Lyme disease. The medical files of 405 women with endometriosis and 200 without endometriosis were studied retrospectively. W…

BACKGROUND: Implantation is a complex initial step in the establishment of a successful pregnancy. Although embryo quality is an important determinant of implantation, temporally coordinated differentiation of endometrial cells to attain ut…

HOX genes, encoding homeodomain transcription factors, are dynamically expressed in endometrium, where they are necessary for endometrial growth, differentiation, and implantation. In human endometrium, the expression of HOXA10 and HOXA11 i…

Protein kinase B (PKB/Akt), a serine/threonine kinase, regulates the function of many cellular proteins involved in apoptosis and proliferation. It was postulated that there is a higher Akt activity in endometriosis compared with normal end…

ObjectiveRecent studies reported that endometriosis could behave as a neoplasmatic process. The purpose of this study is to investigate the family risk of ovarian, colon and prostate cancer in women with endometriosis.Study designA search o…

ObjectiveTo analyze a hypothesis regarding the pathogenesis of endometriosis.DesignRetrospective study.SettingTwo academic endometriosis referral centers.Patient(s)We evaluated operative and pathologic reports of 251 women who underwent lap…

Age, BMI, lifestyle, menstrual status and obstetric history can modulate the endocrine system and, therefore, have been hypothesised to play a role in in-vitro fertilisation (IVF) outcome. We designed a retrospective study, set in a medical…

CONTEXT: Endometriosis is an estrogen-dependent disease characterized by the presence of endometrial tissue outside of the uterine cavity, causing pelvic pain and infertility in 10% of reproductive-aged women. It is unclear why ectopic endo…

ObjectiveTo investigate the familial aggregation and the risk of endometriosis among the female relatives of women with endometriosis. We also compared the epidemiologic characteristics of women with and without family history of endometrio…

ObjectiveFew studies examining the association of endometriosis with the risk of breast cancer. Our goal was to investigate the familial risk of breast cancer in women with endometriosis.DesignRetrospective study.SettingUniversity-based end…

Implantation is a complex process by which the embryo attaches to the endometrium. The human endometrium becomes receptive to the embryo during the luteal phase of the menstrual cycle under the influence of steroid hormones and paracrine fa…

ObjectiveThe association between demographic factors, menstrual and reproductive characteristics, and clinical profile for women with endometriosis was analyzed in a retrospective case-control study.MethodsOver a 6-year period, 535 women wi…

ObjectiveTo investigate the response to controlled ovarian hyperstimulation and ART outcomes in women with advanced-stage endometriosis and previous surgeries at the Yale IVF program between 1996 and 2002.DesignRetrospective case control st…

Endometriosis is characterized by ectopic growth of endometrial tissues. Statins, inhibitors of 3-hydroxy-3methylglutaryl-coenzyme A reductase (HMGCR), have been shown to decrease proliferation of several mesenchymal tissues. Actions of sta…
