Endometriosis (EMs) is an estrogen-dependent, chronic inflammatory disorder characterized by immune microenvironment dysregulation, a critical factor in its pathogenesis. Despite existing therapies, limitations persist, highlighting the urg…

Polycystic ovary syndrome (PCOS) is one of the most common reproductive disorders in women and severely impairs fertility. Extant clinical studies can only provide indirect and plausible evidence to support endometrial dysfunction as an ova…

IntroductionChronic endometritis (CE) is regarded as a potential factor contributing to infertility and embryo implantation failure. The cause of CE remains unclear at present, but it might be associated with intrauterine microbial infectio…

Anti-synthetase syndrome (ASS) is a rare autoimmune condition characterized by the presence of anti-aminoacyl tRNA synthetase (ARS) antibodies and systemic features such as interstitial lung disease and myositis. Although autoimmune disorde…

ObjectivesTuberculosis (TB) is a common cause of infertility in humans, especially in regions with high TB prevalence. However, the impact of latent TB infection (LTBI) on pregnancy outcomes following assisted reproduction in patients with …

PurposeTuberculosis (TB) is a significant factor contributing to infertility. For some infertile patients, chest radiography (CXR) screenings prior to assisted reproductive treatment (ART) reveal old/inactive TB lesions. However, the pregna…

Study questionDoes the type of embryo culture medium affect the birthweight of newborns conceived by ART?Summary answerAfter fresh embryo transfers, singleton newborns in the G5 and HTF groups exhibited higher birthweight z-scores and incre…

Whether and how endometrial aging affects fertility remains unclear. In our in-house clinical cohort at the Center for Reproductive Medicine of Peking University Third Hospital (n = 1,149), we observed adverse pregnancy outcomes in the midd…

Over 75% of failed pregnancies involve implantation defects. Growth factor receptor-bound protein 2 (GRB2) is an adaptor protein involved in signal transduction and cell communication. Here we show that the expression of GRB2 protein is low…

Ovarian steroid hormones-estrogen and progesterone-play a central role in regulating epithelial-stromal interactions in the uterus. These interactions are critical for uterine function, including endometrial receptivity, implantation, and d…

BACKGROUND: To evaluate maternal and perinatal outcomes in women with different adenomyosis phenotypes and to assess the impact of placental attachment site in patients with intrinsic adenomyosis. METHODS: This retrospective cohort study a…

OBJECTIVE: This study explores the metabolic profiles in the peripheral blood of infertile patients with adenomyosis (ADM) to identify key metabolites affecting pregnancy outcomes in these patients undergoing frozen embryo transfer (FET). O…

Endometriosis (EMT) is a common gynecological disease with a strong genetic component, while its precise etiology remains elusive. This study aims to integrate transcriptome-wide association study (TWAS), Mendelian randomization (MR), and b…

Editorial: Impaired receptivity of thin endometrium: the mechanism, hormone intervention and strategies

BACKGROUND: Endometriosis is considered as a systemic disease with the presence of proinflammatory cytokines in the circulation, which drives hypercoagulable state of endometriosis. Currently, endometriosis is classified into four stages: I…

Abstract Background Endometriosis is considered as a systemic disease with the presence of proinflammatory cytokines in the circulation, which drives hypercoagulable state. Currently, endometriosis is classified into four stages: I (minimal…

OBJECTIVE: To identify the transcriptomic changes of ectopic lesions and eutopic endometrial tissues during the progression of endometriosis, we performed transcriptomic analysis in the eutopic endometrium and ectopic lesions. DESIGN: Labo…

Study questionWhat are the roles of maternal 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T/A1298C combination polymorphisms on the embryological and clinical outcomes of IVF/ICSI?Summary answerOur study reveals for the first time t…

To explore the association between uterine volume and in vitro fertilization (IVF) reproductive outcomes of infertile patients with adenomyosis, we performed a retrospective cohort study of infertile patients with adenomyosis who underwent …

BackgroundEctopic pregnancy is more common amongst assisted reproduction cycles and is a cause of significant maternal morbidity. Few predictive markers exist to help identify and modify risk of ectopic pregnancy in preparing for embryo tra…

The present study aimed to investigate the potential effect of fibronectin (FN) in adenomyosis progression. Small guide RNAs were designed to knock down FN expression in Ishikawa cells. The impact of FN on the proliferation, apoptosis, migr…

Recurrent spontaneous abortion (RSA) is a complex multifactorial disease. Recently, the microbiota of the female reproductive tract, as an emerging factor in RSA, has gradually attracted the attention of many clinical researchers. Here, we …

INTRODUCTION: Endometrial thickness is an important parameter to evaluate endometrial receptivity. An appropriate endometrial thickness is necessary for both embryo implantation and maintaining normal pregnancy. Women with thin endometrium …

BACKGROUND: Adenomyosis is commonly encountered in infertile women; however, it is still unclear whether adenomyosis has a detrimental effect on in vitro fertilization and embryo transfer (IVF-ET) outcomes. METHOD: We enrolled 1146 patient…
