Cytokines present within the environment of endometriosis are believed to contribute to the pathogenesis of the disease by promoting inflammatory conditions surrounding the implantation of endometriotic lesions. Interleukin‐17A is a member …

OBJECTIVE: To evaluate endometrial leukemia inhibitor factor (LIF) expression as a marker of endometrial receptivity in women with unexplained infertility (UI). DESIGN: Prospective case-control study. SETTING: University-associated infert…

Resveratrol is a natural phytoestrogen with antiproliferative properties present in red wine, grapes, and berries. Published reports on the effects of resveratrol in human endometrial function are limited. The objective of this study was to…

The p160/steroid receptor coactivator (SRC) family comprises three pleiotropic coregulators (SRC-1, SRC-2, and SRC-3; otherwise known as NCOA1, NCOA2, and NCOA3, respectively), which modulate a wide spectrum of physiological responses and c…

OBJECTIVE: To compare intraobserver and interobserver variation between traditional histological score (HSCORE) and digital HSCORE (D-HSCORE) performed by expert and naive researchers. STUDY DESIGN: Immunohistochemical analysis of beta3 in…

Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII; NR2F2) is an orphan nuclear receptor involved in cell-fate specification, organogenesis, angiogenesis, and metabolism. Ablation of COUP-TFII in the mouse uterus causes …

The endometrium is a hormone ­ dependent tis­ sue that forms the mucosal lining of the inside of the uterus. It is not only an interface between the internal and external environment of a woman’s body, but philosophically speaking, it is th…

The endometrium is ground zero when it comes to understanding how implantation occurs and how it might also fail, resulting in infertility or pregnancy loss. Many of the causes of diminished uterine receptivity are acquired during a woman's…

Lipoxin A4 (LXA4), an endogenous anti-inflammatory and immunomodulatory mediator studied in many disease states, is recently appreciated as a potentially significant player in the endometrium. This eicosanoid, synthesized from arachidonic a…

Adenomyosis is defined by the presence of endometrial glands and stroma within the myometrium. Despite its frequent occurrence, the precise aetiology and physiopathology of adenomyosis is still unknown. WNT/β-catenin signalling molecules ar…

OBJECTIVES: Cell lines derived from human ovarian and endometrial cancers, and their immortalized non-malignant counterparts, are critical tools to investigate and characterize molecular mechanisms underlying gynecologic tumorigenesis, and …

BACKGROUND: Our aim was to study ways to improve IVF success rates in women with suspected endometrial receptivity defects. METHODS: We conducted a retrospective cohort study examining the effect of letrozole (aromatase inhibitor) on integ…

Rapid estrogen effects are mediated by membrane receptors, and evidence suggests a role for both a membrane-associated form of estrogen receptor alpha (ESR1; ERα) and G-protein coupled receptor 30 (GPER; GPR30). Considering estrogen's impor…

Endometriosis is a common disease affecting 40 to 70% of reproductive-aged women with chronic pelvic pain (CPP) and/or infertility. The purpose of this study was to demonstrate the use of a blue dye (methylene blue) to stain peritoneal surf…

OBJECTIVE: To provide a focused review of the scientific literature pertaining to endometrial receptivity. DESIGN: Review of the literature and appraisal of relevant articles. SETTING: Academic teaching hospital. PATIENT(S): Women with i…

Unexplained and recurrent loss of pregnancies is a heartbreaking and frustrating condition. The routine diagnostic workup for pregnancy loss includes hormonal evaluation, screening for genetic or chromosomal defects, immunologic and thrombo…
