The field of reproductive endocrinology and infertility (REI) is at a crossroads; there is a mismatch between demand for reproductive endocrinology, infertility and assisted reproductive technology (ART) services, and availability of care. …

Estrogen receptor 1 (ESR1) and progesterone receptor (PGR) are essential regulators for endometrial receptivity and embryo implantation. Their expression is dysregulated in women with endometriosis-associated infertility. However, the relat…

Endometriosis-associated infertility is a complex condition in which the presence of endometrial-like tissue disrupts implantation and early pregnancy. Epigenetic regulators are critical for implantation and decidualization, yet their contr…

Endometriosis is an estrogen-dependent inflammatory disorder frequently associated with infertility and characterized by progesterone resistance and impaired endometrial receptivity. While ectopic lesions define the disease, accumulating ev…

Over 75% of failed pregnancies involve implantation defects. Growth factor receptor-bound protein 2 (GRB2) is an adaptor protein involved in signal transduction and cell communication. Here we show that the expression of GRB2 protein is low…

Ovarian steroid hormones-estrogen and progesterone-play a central role in regulating epithelial-stromal interactions in the uterus. These interactions are critical for uterine function, including endometrial receptivity, implantation, and d…

PURPOSE: To study whether mid-luteal endometrial B-cell lymphoma 6 (BCL6) or sirtuin-1 (SIRT1) immunostaining in an ovarian stimulation (fresh) in vitro fertilization (IVF) cycle was predictive of risk for endometriosis. Additionally, to ev…

Endometriosis is a common cause of infertility, pelvic pain, and dysmenorrhea and there are prior case reports of lesion detection using an 18F-fluoroestradiol (FES) tracer with positron emission tomography (PET). We aimed to further invest…

An inability to make the diagnosis of endometriosis or evaluate lesion response to treatment without surgery is a clear impediment to understanding the disease and to developing new therapies. The need is particularly strong for rASRM Stage…

Endometriosis is a prevalent and potentially debilitating condition that mostly affects individuals of reproductive age, and often has a substantial diagnostic delay. US is usually the first-line imaging modality used when patients report c…

OBJECTIVE: To identify the transcriptomic changes of ectopic lesions and eutopic endometrial tissues during the progression of endometriosis, we performed transcriptomic analysis in the eutopic endometrium and ectopic lesions. DESIGN: Labo…

PURPOSE: Few investigations have examined the uptake of radiotracers that target the prominent sex-steroid receptors in the uterus across the menstrual cycle and with disease state. We aimed to determine if uptake of the radiotracers that t…

PURPOSE: Endometriosis is an estrogen-dependent disorder of menstruating primates where tissues similar to the inner lining of the uterus exist "ectopically" outside of the uterus. The ectopic endometrium, like the endometrium within the ut…

Endometriosis is an estrogen dependent, chronic inflammatory disease characterized by the growth of endometrial lining outside of the uterus. Mast cells have emerged as key players in regulating not only allergic responses but also other me…

PURPOSE OF REVIEW: To succinctly review the basic mechanisms of implantation and luteal phase endometrial differentiation, the etiologies of impaired endometrial function and receptivity, and the current methods that exist to evaluate and t…

Female subfertility is highly associated with endometriosis. Endometrial progesterone resistance is suggested as a crucial element in the development of endometrial diseases. We report that MIG-6 is downregulated in the endometrium of infer…

INTRODUCTION: Infertility is a common complication of endometriosis. While in vitro fertilisation-embryo transfer (IVF) successfully treats endometriosis-associated infertility, there is some evidence that pregnancy rates may be diminished …

For pregnancy to be established, uterine cells respond to the ovarian hormones, estrogen, and progesterone, via their nuclear receptors, the estrogen receptor (ESR1) and progesterone receptor (PGR). ESR1 and PGR regulate genes by binding ch…

Sirtuin 1 (SIRT1) is a member of the sirtuin family that functions to deacetylate both histones and non-histone proteins. Previous studies have identified significant SIRT1 upregulation in eutopic endometrium from infertile women with endom…
