BACKGROUND: Endometriosis is often diagnosed late due to a lack of noninvasive diagnostic tools and the varied presentation of its symptoms. Identifying risk factors for endometriosis is crucial for reducing diagnosis delays, mitigating the…

PURPOSE: This case-control study investigated whether ovarian endometriosis is associated with altered estrogen metabolism and gut or urogenital microbiota by analyzing enzyme activity, bacterial composition, and variations of estrogen meta…

PURPOSE: Decidualization of endometrial stromal cells involves significant morphological and functional changes in which alpha-smooth muscle actin (αSMA) expression decreases. Meflin, a glycosylphosphatidylinositol-anchored protein, suppres…

BACKGROUND: Endometriosis is increasingly recognized as a disorder of impaired reproductive immune tolerance rather than solely an endocrine disease. Although previous studies have reported inconsistent findings regarding the number of regu…

PURPOSE: In women with unilateral endometriosis, how do ovarian endometriomas and their inflammatory content affect oocyte and embryo quality in affected versus healthy ovaries, and what is the impact on ART outcomes? METHODS: This study, …

PURPOSE: To clarify the efficacy and safety of the estetrol 15 mg/drospirenone 3 mg combination among Japanese women with adenomyosis by post hoc analyses of a previous randomized clinical study. METHODS: Post hoc analyses were performed u…

PURPOSE: To identify risk factors that predict the persistence of noncyclical pelvic pain in patients with endometriosis despite receiving hormone therapy. METHODS: This retrospective study examined 164 patients with histopathologically co…

Abstract Purpose Endometriosis is a chronic gynecological disorder associated with pain symptoms and infertility. The expression of microRNA miR‐29c‐3p is dysregulated in endometriosis. We aimed to identify novel molecular targets of miR‐29…

Purpose: This study evaluated whether embryo cryopreservation before surgery (ECBS) improves clinical outcomes in in vitro fertilization (IVF) patients with endometrioma. Methods: This retrospective study included patients aged 28-42 years …

PURPOSE: This study evaluated the feasibility of single-nucleotide polymorphism (SNP) genotyping using dried blood spot (DBS) samples stored under various conditions, based on the genotyping success rate and concordance with whole blood res…

PURPOSE: To investigate the histopathological association between chronic endometritis (CE) and adenomyosis, focusing on basal endometrial alterations and the potential involvement of tissue injury and repair (TIAR) mechanisms. METHODS: Th…

BACKGROUND: Endometriosis is a challenging disease to treat and one of the leading causes of infertility. Impaired endometrial receptivity, and particularly inadequate decidualization of endometrial stromal cells (ESCs), is a crucial compon…

PURPOSE: Endometriosis is a prevalent gynecological disorder, yet data on the role of trace metal elements in its risk remain limited. We aimed to investigate the relationship between serum copper (Cu), zinc (Zn), iron (Fe), magnesium (Mg) …

Background: Endometriosis is a common gynecological condition, with symptoms including pain and infertility. Regurgitated endometrial cells into the peritoneal cavity encounter hypoxia and nutrient starvation. Endometriotic cells have evolv…

Background: Endometriosis is a common gynecological disease affecting women of reproductive age. Patients with endometriosis frequently experience severe chronic pain and have higher chances to experience infertility. Progesterone resistanc…

BACKGROUND: Numerous efforts have been undertaken to identify biomarkers associated with embryo and oocyte quality to improve the success rate of in vitro fertilization. Metabolomics has gained traction for its ability to detect dynamic bio…

Purpose: -dependent histone deacetylase (HDAC) 1-11 in endometriotic cells and then evaluated the HDACs identified from the screening in ovarian endometrioma (OE) and deep endometriotic (DE) lesions, and to evaluate the therapeutic potentia…

Purpose: To test the theory that invaginated ovarian surface epithelium and endometrial implants on the ovary form ovarian endometriomas. Methods: Adhesion sites of ovarian endometrioma on the peritoneum and consecutive ovarian endometrioma…

Purpose: The aim of this study was to evaluate the dynamic change in staining of Class I HDACs and Hdac6 in lesions harvested serially from different time points in mice with induced endometriosis. In addition, the effect of Hdac8 activatio…

Abstract Purpose This study aimed to explore whether umbilical cord‐derived mesenchymal stem cells (UC‐MSCs) could be used as a therapeutic resource for endometriosis. Methods Of seven cynomolgus monkeys with endometriosis, five were admini…

BACKGROUND: Cesarean scar defects (CSD) are caused by cesarean sections and cause various symptoms. Although there has been no previous consensus on the name of this condition for a long time, it has been named cesarean scar disorder (CSDi)…

Abstract Purpose This study aimed to investigate whether serum leucine‐rich α2‐glycoprotein (LRG) is a useful diagnostic biomarker for endometriosis, including the evaluation of treatment efficacy and exploration of LRG production in endome…

This is the first guidelines for adenomyosis from the Asian Society of Endometriosis and Adenomyosis.

Purpose: To investigate how the extent of fibrosis in adenomyosis lesions contributes to heavy menstrual bleeding (HMB). Methods: We recruited 57 women with histologically confirmed adenomyosis, 29 of whom reported moderate/heavy bleeding (…

BACKGROUND: Reproductive-age women occasionally face the pathological condition of adenomyosis, which is often concurrent with endometriosis. It is believed that endometriosis and adenomyosis increases the risk of obstetric complications. A…
