BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic condition in reproductive-aged women, linked to infertility and long-term cardiometabolic risk. Early identification remains challenging because current diagnosis …

Uterine fibroids are common among women of reproductive age and often recur after treatment. Accurate recurrence prediction is essential for guiding clinical decisions, yet existing models remain inadequate. This study aimed to develop a no…

BACKGROUND: The clinical prognostic factors for ovarian clear cell carcinoma (OCCC) are limited, and we aim to construct a model to predict the survival of OCCC patients. METHODS: Data were extracted from the SEER database for patients dia…

Diabetic kidney disease (DKD) is recognized as one of the leading causes of chronic kidney disease (CKD) and end-stage kidney disease (ESKD) worldwide, representing a rapidly growing global public health concern. Despite significant advance…

Abstract Background : Incarcerated gravid uterus (IGU), which is characterized by entrapment of the retroverted uterus within the pelvis during the gestational period, is an uncommon condition but might potentially lead to serious mater…

Natural killer (NK) cells are critical regulators of immune processes during early pregnancy, playing a key role in maintaining maternal-foetal immune tolerance and supporting successful implantation. In particular, uterine NK cells, a spec…

In clinical drug development, two fundamental questions must be addressed: what is the success rate of drugs in clinical trial; how does such rate change over time. Here, a dynamic strategy for calculating clinical trial success rate (ClinS…

Abstract Background: Endometrial receptivity, a critical prerequisite for successful pregnancy, is impaired in women with endometriosis. Plasma membrane transformation (PMT), a key process involving dynamic remodeling of endometrial epithe…

We aimed to examine abnormal oxidative lipid levels and their related mechanisms in EM-associated infertility. Through liquid chromatography tandem mass spectrometry analysis, decreased levels of epoxyeicosatrienoic acids (EETs), which have…

OBJECTIVES: To assess the potential impact of years of education, which serves as a measure of socioeconomic inequality, on the occurrence of endometriosis, and to quantify the potential influence of modifiable factors as mediators. METHOD…

This retrospective cohort study evaluates the clinical effects of an antagonist protocol on in vitro fertilization and intracytoplasmic sperm injection among infertile women with polycystic ovary syndrome. A propensity score matching analys…

BACKGROUND: Diabetes mellitus (DM) is one of the most common endocrine disorders affecting various physiological systems and tissues, including the reproductive organs in men. However, the consequences of DM for male individuals undergoing …

DNA methylation is a common endogenous chemical modification in eukaryotic DNA, primarily involving the covalent attachment of a methyl group to the fifth carbon of cytosine residues, leading to the formation of 5-methylcytosine (5mC). This…

Severe acute pancreatitis (SAP) is a common abdominal emergency in clinical practice. Approximately 20%-40% of patients with SAP will be associated with acute lung injury (SAP-ALI), which is a major cause of death. Emodin (EMO) is a natural…

BACKGROUND: Infertility affects millions globally, with significant social, emotional, and economic consequences. While frozen-thawed embryo transfer (FET) is a cornerstone of assisted reproductive technology, its clinical pregnancy success…

Epigenetic regulation of placental development and pregnancy-related disease processes has recently been a hot research topic. Implantation and subsequent placental development depend on carefully orchestrated interactions between fetal and…

BACKGROUND: Endometriosis is currently considered a chronic disease for which long-term medical treatment is needed. The aim of this study was to evaluate the long-term efficacy and safety of dydrogesterone in Chinese women with endometrios…

OBJECTIVE: To explore the micro blood flow characteristics of normal singleton pregnancy placenta in middle and late pregnancy based on microvascular flow (MV-Flow) imaging. METHODS: We conducted a retrospective cohort study. Clinical reco…

Extracellular vesicles (EVs) facilitate intercellular communication and the conveyance of bioactive substances, including proteins, lipids, and nucleic acids. They play a significant role in various reproductive biological processes, includ…

Protein O-GlcNAcylation is a post-translational modification coupled to cellular metabolic plasticity. Aberrant O-GlcNAcylation has been observed in many cancers including endometrial cancer (EC), a common malignancy in women. However, clin…

Infertility affects approximately 15% of couples at child-bearing ages and assisted reproductive technologies (ART), especially in vitro fertilization and embryo transfer (IVF-ET), provided infertile patients with an effective solution. The…

Diminished ovarian reserve (DOR) poses significant challenges in reproductive health, with emerging evidence implicating DNA damage repair pathways. While GADD45A is a critical regulator of DNA repair, cell cycle and apoptosis, its role in …

OBJECTIVE: Endometriosis (EMT) is a prevalent gynecological disorder characterized by chronic pain, menstrual irregularities, and infertility. This study aims to evaluate the global burden of EMT from 1990 to 2021 and to project trends up t…

BACKGROUND: Endometriosis is a major contributor to infertility and pelvic pain, which brings a significant burden on family and society. Although the data of endometriosis in Global Burden of Disease (GBD) 2019 was reviewed, no updated ana…

The skeletal muscle is highly susceptible to injury in daily life. Severe skeletal muscle injuries often result in incomplete regeneration, leading to functional impairment. In clinical practice, understanding the extent of skeletal muscle …
