Endometriosis (EM) is driven by immune dysregulation and macrophage dysfunction, yet the underlying mechanisms remain unclear. Here, metabolomic profiling revealed excessive itaconate accumulation in EM lesions, primarily due to elevated ci…

OBJECTIVE: To investigate the incidence of postoperative venous thromboembolism in women with uterine adenomyosis treated using different surgical methods, and to evaluate the associated clinical and laboratory parameters, including thrombo…

In brief: Abnormal glucose metabolism may be involved in the pathogenesis of endometriosis. The present study identifies that highly expressed H19 leads to increased aerobic glycolysis and histone lactylation levels in endometriosis. Abstra…

Routine histopathological examination of hernia sac in adults remains a controversial topic. We undertook a retrospective study to assess possible clinical benefits of pathological examination of hernia sac specimens. Our pathology database…

Introduction: This study aimed to compare the pregnancy outcomes of different endometrial preparation protocols in patients with adenomyosis and thin endometrium during frozen embryo transfer. Methods: The study, which was conducted at the …

The influence of endometrioma on oocyte and embryo competence is inconclusive. Furthermore, the benefits of surgical treatment remain uncertain. This study aimed to investigate the effect of endometrioma on oocyte and embryo quality from a …

Aims: The primary aim of the current study was to elucidate the function of the stimulator of interferon genes (STING) in the eutopic endometrium of women with endometriosis. Materials and Methods: STING expression and signaling pathways we…

PURPOSE: The purpose of the study was whether endometriosis influences IVF/ICSI and subsequent pregnancy and obstetric outcomes. METHODS: Searches were performed on PubMed, EMBASE, Medline, and Web of Science. Most of the included studies …

Gonadotropin-releasing hormone agonist (GnRH-a) is generally added to the improve pregnancy outcomes of hormone replacement therapy cycles among patients with adenomyosis. We aimed to investigate whether adding GnRH-a can result in better p…

Abstract Gonadotropin-releasing hormone agonist(GnRH-a) is generally added to improve pregnancy outcomes of adenomyosis based hormone replacement therapy cycle. Our objective in this study is to investigate whether adding GnRH-a can obtain …

Background: Reproductive outcomes after fresh in vitro fertilization/intracytoplasmic sperm injection–embryo transfer (IVF/ICSI–ET) cycles are diverse in infertile women with a history of ovarian cystectomy for endometriomas. We aimed to de…

Abstract Background : Recent studies have confirmed that endometriosis is a chronic inflammatory disease. In our previous work, we found that STING (stimulator of interferon genes) was differentially expressed in eutopic endometrium and con…

Background: The association between endometriosis and embryological outcomes remains uncertain. The meta-analysis aimed to evaluate the impact of endometriosis on embryo quality. Methods: A systematic review and meta-analysis was conducted …

Purpose: The aim of this study was to investigate the effect of human chorionic gonadotropin (hCG) in hormone replacement (HT) regime for frozen thawed embryo transfer in women with endometriosis (EM). Methods: We performed a retrospective,…

Abstract Purpose To investigate the effect of hCG in hormone replacement regime for frozen thawed embryo transfer in women with endometriosis. Methods We performed a retrospective, database-searched cohort study. The data of endometriosis p…

Fibrotic tissue may contribute to the origin of some endometriosis-related symptoms, such as chronic pelvic pain and infertility. Alterations in the H19/miR-216a-5p/ACTA2 pathway may mediate the regulation of eutopic endometrial stromal cel…
