OBJECTIVE: The objective of the study was to evaluate whether anti-Müllerian hormone (AMH) is associated with fecundability among women with proven fecundity and a history of pregnancy loss. DESIGN: This was a prospective cohort study with…

CONTEXT: TAK-385 is a highly selective, oral, nonpeptide GnRH antagonist being investigated as a possible prostate cancer treatment. OBJECTIVE: The objectives were to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics of…

CONTEXT: Although phthalates were shown to have several negative effects on reproductive function in animals, its role in the pathogenesis of endometriosis remains to be elucidated. OBJECTIVE: We aimed to investigate the in vitro and in vi…

CONTEXT: Late-term pregnancy may lead to maternal and neonatal morbidity and mortality. Mice null for the progesterone receptor co-regulator Krüppel-like Factor 9 (KLF9) exhibit delayed parturition and increased incidence of neonatal deaths…

CONTEXT: Human endometriosis (EMS) is characterized by insufficient apoptosis. Our previous studies have shown elevated CD147 expression in human endometriotic tissues and its involvement in endometrial cell apoptosis. However, the exact un…

CONTEXT: Mineralocorticoid synthesis by the nonhuman primate periovulatory follicle enhances luteinization. Whether a similar event occurs in women undergoing in vitro fertilization (IVF) is unknown. OBJECTIVE: The objective of the study w…

CONTEXT: In a previous microarray analysis, GRB2-associated binding protein 1 (GAB1), a docking protein closely related to the insulin receptor substrate, was down-regulated in endometrium of women with polycystic ovary syndrome (PCOS). OB…

CONTEXT: Endometriosis is a common gynecological disease affecting one in 10 women of reproductive age and is a major cause of pelvic pain and impaired fertility. Endometrial stromal cells of women with endometriosis exhibit a reduced respo…

BACKGROUND: In endometriosis, the establishment and subsistence of ectopic lesions outside the endometrium suggest an altered cellular state for pathological hyperplasia. Sphingolipids are bioactive compounds, and their biosynthesis and met…

CONTEXT: Ovarian suppression is a common treatment for endometriosis-associated pelvic pain. Its exact mechanism of action is poorly understood, although it is assumed to reflect reduced production/action of estrogens. OBJECTIVE: The objec…

CONTEXT: Aberrant sex steroid signaling is suggested to promote endometriosis growth by several mechanisms, and the tissue concentrations of sex steroids are key determinants of the hormone action. However, their concentrations are only sup…

CONTEXT: Although adequate luteal hormone production is essential for establishing pregnancy, luteal phase deficiency (LPD) is poorly characterized among eumenorrheic women. OBJECTIVE: We assessed the prevalence and overlap of two establis…

CONTEXT: Endometriosis is an estrogen-dependent disease affecting reproductive women. Metformin could have a therapeutic effect on endometriosis through regulation of local estrogen production. OBJECTS: The aim of this study was to investi…

CONTEXT: This report presents original, combined mode of treatment of preinvasive endometrial cancer (IA/G1) in young women with polycystic ovarian syndrome. OBJECTIVES: The objective of the study was the assessment of treatment with natur…

BACKGROUND: Cytokines and growth factors play important roles in endometrial function and the pathogenesis of endometriosis. mRNAs encoding cytokines and growth factors undergo rapid turnover; primarily mediated by adenosine- and uridine-ri…

CONTEXT: Endometriosis is an estrogen-dependent disease, and estrogen is overproduced by abnormally elevated aromatase in endometriotic tissues. Peroxisome proliferator-activated receptor gamma, coactivator 1α (PGC-1α) is a transcriptional …

CONTEXT: Endometriosis is one of the most common gynecological diseases in women with a prevalence rate of approximately 10%. Chronic pelvic inflammation has been observed in patients with endometriosis and is associated with disease severi…

CONTEXT: TGF-β is believed to play a major role in the etiology of peritoneal endometriosis. In tumors, TGF-β induces the metabolic conversion of glucose to lactate via glycolysis, a process referred to as the "Warburg effect." Lactate incr…

CONTEXT: Vitamin D deficiency is common among reproductive-aged women and has a role in female reproduction. OBJECTIVE: This study evaluated the role of 1,25-dihydroxyvitamin D3 (vit D3) in ovarian follicular development and steroidogenesi…

CONTEXT: Accumulating evidence suggests that various epigenetic aberrations play definite roles in the pathogenesis of endometriosis. OBJECTIVE: The objective of the study was to determine the epigenetically silenced genes by histone deace…

OBJECTIVE: The objective of the study was to evaluate the current state of clinical assays for estradiol in the context of their applications. PARTICIPANTS: The participants were appointed by the Council of The Endocrine Society and charge…

CONTEXT: Anovulation is likely responsible for 20% of female infertility. Although clomiphene citrate remains the first-line therapy for ovulation induction in anovulatory patients who are not estrogen-deficient and to treat unexplained inf…

CONTEXT: Retinoic acid (RA) may promote survival or apoptosis of cells, depending on the levels of binding proteins: apoptosis-inducing cellular RA binding protein 2 (CRABP2), and cell survival-promoting fatty acid binding protein 5 (FABP5)…

BACKGROUND: Decidualizing human endometrial stromal cells (HESCs) profoundly up-regulate 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1), the enzyme that converts inert cortisone to active cortisol. We postulated that the induction of a c…

CONTEXT: The human endometrium is a complex multicellular tissue subject to cyclical fluctuations in ovarian-derived steroid hormones. Fertile cycles are characterized by differentiation (decidualization) of endometrial stromal cells (ESC).…
