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: Randomised controlled trials (RCTs) evaluating ectopic pregnancy have reported many different outcomes, which are themselves often defined and measured in distinct ways. This level of variation results in an inability to compare…

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 …

Sex and aging influence the human immune system, resulting in disparate responses to infection, autoimmunity, and cancer. However, the impact of sex and aging on the immune system is not yet fully elucidated. Using small conditional RNA seq…

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…

INTRODUCTION: Perioperative infections may be considered predictors of caesarean scar defect (CSD), and multidose antibiotics have a protective effect against CSD. However, the ability of adjunctive azithromycin combined with cephalosporin …

OBJECTIVE: To evaluate fertility intensions among couples in Shanghai under the novel coronavirus infection (COVID-19) pandemic against the backdrop of persistently low fertility. METHODS: A cross-sectional study was carried out using data…

BACKGROUND: Ovarian teratoma-associated anti-N-methyl-D-aspartate receptor encephalitis (NMDAR-E) is a severe autoimmune neurological disorder, and the influence of teratoma-induced autoantibodies on the pathogenesis remains unclear. METHO…

Breast tumor initiating cells (BTICs) with ALDH+CD24-CD44+ phenotype are the most tumorigenic and invasive cell population in breast cancer. However, the molecular mechanisms are still unclear. Here, it is found that a negative immune regul…

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…

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

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, understanding of t…

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 ut…

BACKGROUND: Despite limited information on neonatal safety, the transfer of frozen-thawed cleavage-stage embryos with blastomere loss is common in women undergoing in vitro fertilization. We aimed to evaluate the pregnancy outcomes and safe…

Adenomyosis, a benign invasion of endometrium, is closely related to endometriosis. Cysteine-rich 61 (Cyr61), a protein present in all endometrial tissues and menstrual effluents, is known to be associated with endometriosis. However, its r…

The long-lasting nociceptive transmission under various visceral pain conditions involves transcriptional and/or translational alter-ation in neurotransmitter and receptor expression as well as modification of neuronal function, morphology …

OBJECTIVE: To identify risk factors for ovarian pregnancy (OP) and compare clinical features between OP and tubal pregnancy (TP) patients. DESIGN: Case-control study. SETTING: University hospital. PARTICIPANTS: A case-control study was c…

Objective To investigate the clinical characteristics and treatmentof ureteral endometriosis.Methods A retrospective analysis was made on the clinical data of 16 cases of ureteral endometriosis of the Department of Vrology,Beijing Friendshi…

BACKGROUND: Endometriosis (EM) is highly associated with infertility. The precise mechanism underlying EM-associated infertility remains controversial. This study aimed to investigate the pathogenesis of infertility in women with EM by comp…

OBJECTIVE: To establish a non-invasive, repeatable and dynamic study method in endometriosis rat model using magnetic resonance imaging (MRI), in order to explore the magnetic resonance characteristics of the model. METHOD: Endometrium tis…
