The human endometrial immune landscape is critical for homeostasis and pregnancy success, yet its dynamic remodeling across the menstrual cycle and in pathology remains poorly characterized. Here, we construct a comprehensive immune cell at…

In brief: Chronic endometritis (CE) impairs endometrial receptivity via unknown mechanisms. This study reveals that suppression of the C/EBPδ-sphingosine kinase 1 (SphK1)-sphingosine-1-phosphate (S1P) axis in CE leads to decidualization def…

Adenomyosis, characterized by the invasion of endometrial cells into the myometrium, may disrupt immune homeostasis within the eutopic endometrium, thereby impairing endometrial receptivity. This retrospective case-control study aimed to in…

PURPOSE: This study aimed to develop international expert consensus statements on chronic endometritis (CE) through a comprehensive literature review of existing evidence and a modified Delphi approach. METHODS: Ten panelists of the Japan …

Adenomyosis is characterized by the invasion of endometrial glands and stroma into the myometrium. Its clinical manifestations often include dysmenorrhoea, excessive menstrual bleeding and infertility. Reduced pregnancy and live birth rates…

BACKGROUND: Although azithromycin has demonstrated potential therapeutic efficacy in the treatment of chronic endometritis (CE), comprehensive studies on the optimal timing of administration are lacking. Our study aims to evaluate the impac…

BACKGROUND: Chronic endometritis (CE) is a persistent inflammatory condition associated with adverse pregnancy outcomes. Although impaired endometrial angiogenesis is thought to contribute to its pathogenesis, the underlying molecular mecha…

Chronic endometritis (CE) is a persistent inflammatory disorder of the endometrium, typically marked by abnormal plasma cell infiltration. It is closely associated with adverse pregnancy outcomes. The pathogenesis of CE involves a complex i…

As a complex chronic gynecological disorder characterized by multifaceted etiology involving genetics, environment, immunity and inflammation, endometriosis (EM) has long been a significant concern for women of reproductive age worldwide. T…

BACKGROUND: Chronic endometritis (CE) has been widely recognized as a potential cause of infertility, however, access to effective treatment is a formidable challenge due to the rudimentary understanding of the pathogenesis of persistent CE…

BACKGROUND: Latent Mycobacterium tuberculosis infection (LTBI) is common among patients with infertility, yet its effects on ovarian reserve function and pregnancy outcomes in women undergoing assisted reproductive technology (ART) remain u…

OBJECTIVE: This study was conducted to determine the influence of the number of CD138+ cells in the proliferative endometrium on pregnancy outcomes. METHODS: This retrospective cohort study was conducted from January to August 2018. A tota…

RESEARCH QUESTION: Do endometrial preparation protocols have an effect on pregnancy outcomes in patients with cured chronic endometritis? DESIGN: A retrospective study was conducted on 3721 infertile patients from December 2018 to August 2…

The aim of this work was to identify the transcriptomic characteristics of the endometrium in normoweight and overweight/obese polycystic ovary syndrome (PCOS) potentially underlying the pathogenesis. This study included 38 patients undergo…

Women with endometriosis may have a defective immune system. However, evidence of the immune responses of endometriosis patients with a history of endometriosis surgery is lacking, and the association between the location of endometriosis l…

BACKGROUND: Indoleamine 2,3-dioxygenase (IDO) has been reported to play a key role in placental development during normal pregnancy. However, the question of whether endometrial IDO expression affects in vitro fertilization (IVF) pregnancy …
