In a murine model, we have linked early life toxicant exposure to reduced uterine sensitivity to progesterone, a phenotype we had previously associated with inflammation in endometriosis patients. Subsequent studies revealed that developmen…

Endometriosis is a common, complex gynecologic disorder characterized by the presence of endometrial glands and stroma at extrauterine (ectopic) sites. In women who develop this disease, alterations in specific biological processes involvin…

Endometriosis is an often painful disorder in which the endometrial glands and stroma grow outside the uterus. The disease affects women's quality of life and is a common cause of infertility. In this review, we describe promising new devel…

ObjectiveTo examine the impact of a recent surgery on development of endometriosis-related adhesions in a chimeric model and to determine the therapeutic efficacy of pioglitazone (PIO).DesignHuman endometrial biopsies were maintained in E(2…

Development of endometriosis likely requires multiple, interactive mechanisms involving both the endocrine and immune systems. Environmental toxicants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), are of particular interest as potent…

A recent survey in the United States identified 287 different chemicals in human cord blood, demonstrating the significant exposure of women and their children to a wide array of environmental toxicants. While reducing contamination and exp…

OBJECTIVE: To develop a chimeric human/mouse model of experimental endometriosis for the examination of the role of human immune cells in this disease. DESIGN: Laboratory-based study. SETTING: University-affiliated medical center. PATIEN…

Endometriosis is a common gynecologic disorder characterized by ectopic attachment and growth of endometrial tissues. Resveratrol is a natural polyphenol with antiproliferative and anti-inflammatory properties. Our objective was to study th…

Endometriosis is a major cause of chronic pain, infertility, medical and surgical interventions, and health care expenditures. Tissue factor (TF), the primary initiator of coagulation and a modulator of angiogenesis, is not normally express…

CONTEXT: Endometriosis is a common condition associated with infertility and pelvic pain in women. Recent in vitro studies have shown that statins decrease proliferation of endometrial stroma (ES) and inhibit angiogenesis. OBJECTIVE: The ai…

Laboratory and population-based studies suggest that exposure to environmental toxicants may be one of several triggers for the development of endometriosis. We discuss evidence that modulation of the endometrial endocrine-immune interface …

Whether environmental toxicants impact an individual woman's risk for developing endometriosis remains uncertain. Although the growth of endometrial glands and stroma at extra-uterine sites is associated with retrograde menstruation, our st…

CONTEXT: Endometriosis, the growth of endometrial tissue outside the uterus, is principally an estrogen-dependent disease. In contrast, exposure to progesterone during pregnancy or therapeutically has been shown to provide benefit to some w…

Two recent studies reported in this issue of Fertility and Sterility have explored important issues regarding the understanding and diagnosing of endometriosis. These studies emphasize the complexity of endometriosis and underscore the diff…

OBJECTIVE: To analyze endometrial progesterone receptor (PR) expression in women with endometriosis compared with disease-free women and to assess the impact of in vitro 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure on PR isotype expr…

ObjectiveTo discuss the role that reduced endometrial responsiveness to progesterone (P) might play in the pathophysiology of endometriosis.DesignA review of experimental evidence regarding the failure of P to regulate the expression of mat…

BACKGROUND: Endometriosis is a common gynaecological problem of uncertain aetiology. It affects primarily young, reproductive-aged women and can result in chronic pelvic pain and infertility. Current approved therapies have significant side…

Endometriosis is a disease in which the lining of the uterus (endometrium), shed at the time of menstruation, becomes established at sites such as the peritoneum and ovaries. These explants develop a rich blood supply that enables them to s…

Retrograde menstruation represents a plausible explanation for the development of most cases of endometriosis; nevertheless, additional factors must contribute to the development of disease in only 10 to 20% of women. The discriminating fac…

Endometriosis is a complex disease that can develop as a consequence of retrograde menstruation, occurring in association with the cyclic loss of endometrial tissue in primates and humans. In addition, progression of disease parallels a wom…

The endometrial lining of the human uterus is a highly specialized, steroid-sensitive tissue. Throughout the reproductive years, the endometrium undergoes dramatic cycles of growth, differentiation, and breakdown under the influence of ovar…

The human endometrium exhibits regular cycles of growth, differentiation, and breakdown in response to changing levels of ovarian steroids. Following the tissue loss and repair processes of menstruation, rising levels of estradiol initiate …

The cyclic expression of matrix metalloproteinases (MMPs) by human endometrium has been suggested to play a role in the invasive process necessary to establish endometriosis. The ability of progesterone exposure to inhibit endometrial MMP-3…
