Background: This study aims to investigate the impact of chronic endometritis (CE) diagnosis and treatment on pregnancy outcomes during hysteroscopic fallopian tube catheterization combined with laparoscopy in infertility patients with pelv…

Endometrial immune disorders create an inhospitable endometrial environment for embryonic nidation in endometriosis. CD8 + tissue resident memory T cells (CD8 +TRM) are abundant tissue resident immune cells in endometrium, but the effect of…

BACKGROUND: Endometriosis is highly prevalent but remains under-researched. This study, using the latest data, aims to provide a comprehensive assessment of the burden of endometriosis on a global scale. METHODS: Based on data from the Glo…

Iron is an essential micronutrient element for human. It participates in energy metabolism, enzyme activation, immune system and other metabolic functions. In this review, the potential role of iron in female reproductive health were consid…

Endometriosis is a chronic gynecological disorder characterized by progressive fibrosis, which is closely associated with clinical symptoms such as dysmenorrhea and infertility. While myofibroblast activation is central to fibrogenesis, the…

BACKGROUND: High rates of infertility and pregnancy complications in patients with intrauterine adhesion (IUA) even after surgical repair may be associated with poor endometrial receptivity (ER). In our previous study, we found that changes…

BACKGROUND: For patients with a unicornuate uterus and a symptomatic rudimentary horn, the definitive treatment is surgical removal of the horn, which can be performed using either laparoscopy or laparotomy. Usually, the rudimentary horn ap…

INTRODUCTION: Ultrasound has become a routine method for endometrial receptivity (ER) evaluation. However, there is controversy over the independent evaluation values of various ultrasound indicators. Some researchers have designed multi-in…

OBJECTIVE: To clarify whether intrauterine adhesions (IUAs) affect endometrial receptivity (ER) on the day of ovulation and to compare patients with mild and moderate-severe adhesions. METHODS: This prospective cohort study included 592 in…

OBJECTIVE: To obtain quantitative and comprehensive results of the changes in comprehensive ER indicators from ovulation day to transplantation day by ultrasonography during the natural frozen-thawed embryo transfer cycle (FET). METHODS: T…

OBJECTIVE: To investigate the impact of endometriosis on the therapeutic effect of hysteroscopic fallopian tube catheterization combined with laparoscopy in infertile patients with proximal tubal obstruction. METHODS: We conducted a retros…

Endometriosis is a hormone-dependent disease associated with impaired immunoregulation. In our recent study, we have characterized the trascriptomic transformation of eutopic endometrium from patients with minimal/mild endometriosis and con…

Endometriosis is a common inflammatory disorder in women of reproductive age due to an abnormal endometrial immune environment and is associated with infertility. This study aimed to systematically understand the endometrial leukocyte types…

The prevalence of endometriosis is approximately 10% in women of reproductive age, and 30-50% of women with endometriosis are infertile. Metformin has been reported to inhibit the growth of ectopic lesions in endometriosis. However, its eff…

We first reported that the Hippo-YAP signaling pathway plays a critical role in the pathogenesis of endometriosis (EMS). Autophagy is also related to the invasion ability of endometrial cells and is involved in the pathogenesis of EMS throu…

OBJECTIVE: Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disorder. Recent studies report that long non-coding RNAs (lncRNAs) play vital roles in the pathogenesis of various diseases. This study explored the molecular mechanis…

AIM: Progesterone resistance is an epigenetic factor that reduces endometrial receptivity and causes implantation failure in women with endometriosis. In addition, dysregulated miRNAs contribute to the underlying pathogenic mechanisms of en…

RATIONALE: Intravenous leiomyomatosis (IVL) is a rare and special type of smooth muscle tumor originating in the uterus. It is classified as a benign disease according to its histological features but shows the behavioral characteristics of…

Abstract Background: The infertile patients with endometriosis had a higher prevalence of endometrial polyps. The effect of endometrial polyps on pregnancy outcomes in endometriosis-associated infertility patients is unclear. This study ass…

The pelvic organ prolapse (POP) repair systems used in China are imported and expensive. Our aim was to compare the efficacy and safety of a self-developed pelvic floor repair system versus the Avaulta system.This was a multicenter, randomi…

BACKGROUND: Although Caesarean scar pregnancy (CSP) is rare, it can cause life-threatening complications. The increasing rate of Cesarean delivery plus rapid development of in vitro fertilization-embryo transfer (IVF-ET) may increase the oc…
