OBJECTIVE: To determine the future priorities for ectopic pregnancy research. DESIGN: Potential research questions were collated from an initial international survey, a systematic review of clinical practice guidelines, and Cochrane system…

RESEARCH QUESTION: How does tubal endometriosis (TEM) impact the morphology and ultrastructure of tubal epithelium, and what are the underlying pathophysiological mechanisms of TEM? DESIGN: Epithelial samples of fallopian tube were collect…

PURPOSE: To investigate and compare the clinical characteristics and risk factors between intrinsic and extrinsic adenomyosis (AM), as well as the differences in their perioperative management and findings in the two subtypes. METHODS: This…

INTRODUCTION: A symptomatic uterine niche is a long-term complication after a cesarean section (CS). A group of international niche experts reached consensus on a standardized definition of a disorder caused by a symptomatic niche, named ce…

INTRODUCTION: Endometriosis (EM) is an estrogen-dependent benign gynecologic disease affecting approximately 10% of reproductive-age women with a high recurrence rate, but lacks reliable biomarkers. No previous studies have investigated the…

Background: , has proven to be an effective therapeutic agent for EM. However, the precise molecular mechanisms underlying its efficacy remain unclear. Objective: This study aims to elucidate the underlying mechanisms of WJT in the treatmen…

Endometriosis is a gynecological disease related to menstruation that affects nearly 10% of reproductive-age women. However, so far, there are no reliable diagnostic biomarkers for endometriosis, causing a delay in diagnosis of 6.7 ± 6.2 ye…

RESEARCH QUESTION: What is the effect of tubal endometriosis on tubal epithelial ultrastructure and is there a differential expression of exosomal microRNAs (miRNAs) in tubal fluid which may affect tubal infertility? DESIGN: Human fallopia…

Objective: To investigate the impact of endometriosis (EMS) on granulosa cell function and elucidate the molecular mechanisms involved. Methods: RNA sequencing, differential expression analysis, Gene Ontology (GO) and Kyoto Encyclopedia of …

Triptorelin is one of the most commonly used gonadotropin-releasing hormone agonists and has been used in the treatment of deep infiltrating endometriosis (DIE). This study aimed to evaluate the efficacy and safety of up to 24 weeks of trip…

BACKGROUND: channel 3 (SK3) is abundantly expressed in platelet-derived growth factor receptor α positive (PDGFRα+) cells and was reported to be important for the relaxation of smooth muscle. The present study aims to explore the expression…

BACKGROUND: The prevalence of perineal endometriosis (PEM) is low among women with endometriosis (EM) treated by surgery. It manifests as hard or cystic nodules with pain in the perineal wounds and surrounding areas. Implantation theory is …

Abstract OBJECTIVE: To investigate the effects of peritoneal endometriosis on rat ovaries. METHODS: A rat model of peritoneal endometriosis was established by autologous transplantation. qPCR was performed to measure mRNA levels of steroid …

Chronic fatigue syndrome (CFS) is characterized by extreme fatigue and disabling symptoms. Women with CFS often have a high risk of gynaecological problems such as irregular menstruation, endometriosis and pelvic pain and sexual dysfunction…

OBJECTIVE: To compare the efficacy of postoperative adjuvant treatment (gonadotropin-releasing hormone agonists [GnRHas] and oral contraceptives [OCs]) and expectant treatment in preventing recurrent dysmenorrhea following conservative lapa…

Tubal endometriosis (tubal EM) is a subtype of endometriosis (EM) associated with fallopian tube impairments and infertility. Since the molecular mechanism underlying tubal EM is not clear, we assume that an aberrant transcriptome of fallop…

OBJECTIVE: To evaluate the efficacy and safety of up to 24 weeks of triptorelin treatment after conservative surgery for deep infiltrating endometriosis (DIE). DESIGN: Multicentre, prospective, non-interventional. SETTING: 18 tertiary hospi…

MicroRNA (miRNA) expression profiles in tubal endometriosis (EM) are still poorly understood. In this study, we analyzed the differential expression of miRNAs and the related gene networks and signaling pathways in tubal EM. Four tubal epith…

Hysterectomy has been the definitive treatment option for symptomatic adenomyosis and/or adenomyoma when medical or other conservative treatments fail to control the symptoms. Conservative surgery has already developed as an alternative tre…

To reassess the prevalence of fallopian tube endometriosis (EM), and its associated clinicopathologic characteristics and risk factors. Cross-sectional study was conducted from June 2016 to August 2017. Unpregnant premenopausal women who un…

Abstract Previous studies revealed the increasing risk of tubal pregnancy following failure of levonorgestrel (LNG)‐induced emergency contraception, which was attributed to the reduced ciliary motility in response to LNG. However, understan…

BACKGROUND: Pelvic endometriosis (EM) and adenomyosis (AM) have different effects on the fallopian tube. This study aimed to assess the transport capability of the fallopian tube in women with pelvic EM or AM. METHODS: Twenty women with ute…
