Endometriosis is an enigmatic disease affecting up to 10% of reproductive-aged women causing pain and infertility. Up to 50% of women with endometriosis are infertile, and agreement about treatment options has been difficult to establish. T…

Progesterone is essential for endometrial receptivity and successful establishment of pregnancy. Either an insufficient progesterone concentration or an insufficient response to progesterone, therefore can lead to infertility and pregnancy …

Prunella vulgaris (PV), a commonly used Chinese herb, also known as Self-heal, has a wide range of reported medicinal activities. By screening multiple herbs using the endometrial cancer cell line, ECC-1, and an alkaline phosphatase detecti…

Endometriosis is a common gynecologic disorder characterized by pain and infertility. In addition to estrogen dependence, progesterone resistance is an emerging feature of this disorder. Specifically, a delayed transition from the prolifera…

PROBLEM: The lack of a reliable method for early non-invasive detection of endometriosis often results in delayed diagnosis. The aim of this study was to test the hypothesis that the plasma concentration of complement factor C3a (anaphylato…

Pregnancy is dependent upon the endometrium acquiring a receptive phenotype that facilitates apposition, adhesion and invasion of a developmentally competent embryo. Surface-enhanced laser desorption/ionization time-of-flight mass spectrome…

Cyr61 is overexpressed in PCOS endometrium, reflecting a heightened responsiveness to estrogen. As a unique marker of estrogen action, Cyr61 may be an early biomarker for the development of hyperplasia or adenocarcinoma in this group of wom…

Because endometriosis, a chronic disease affecting 7% to 10% of women, is associated with immunologic aberrations, the authors hypothesize that the presence of specific immune alterations may be diagnostic. Autoantibodies were assayed by We…

The identification of molecular differences in the endometrium of women with endometriosis is an important step toward understanding the pathogenesis of this condition and toward developing novel strategies for the treatment of associated i…

The role of the endometrium is to establish and maintain pregnancy. Endometrial receptivity is established during the mid-secretory phase, between cycle day (CD) 20 to 24, or 6 to 10 days after ovulation. In some cases of infertility or rec…

Endometriosis is a disorder that affects 5% of the normal population but is present in up to 40% of women with pelvic pain and/or infertility. Recent evidence suggests that the endometrium of women with endometriosis exhibits progesterone i…

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…

Endometriosis is clinically associated with pelvic pain and infertility, with implantation failure strongly suggested as an underlying cause for the observed infertility. Increasingly, studies are demonstrating biochemical and molecular dif…

Endometriosis is clinically associated with pelvic pain and infertility, with implantation failure strongly suggested as an underlying cause for the observed infertility. Eutopic endometrium of women with endometriosis provides a unique exp…
