ObjectiveTo identify risk factors influencing clinical pregnancy outcomes in infertile men undergoing intracytoplasmic sperm injection (lCSl) and to establish and validate a nomogram prediction model.MethodsA total of 1,037 infertile men wh…

BackgroundCombined oral contraceptives (COCs) can relieve dysmenorrhea, but utilization is low in Chinese women. This systematic literature review was conducted to summarize the design of clinical studies and the effectiveness and safety of…

BACKGROUND: Premature ovarian failure (POF), affecting women under 40, is characterized by early loss of ovarian function with unclear pathogenesis. This study evaluates the role and diagnostic performance of intestinal flora (IF) combined …

ObjectiveCurrently, it has been reported that uterine microbiota affected pregnancy outcomes in assisted reproductive technology, but little was known in obese women. Thus, this study aims to explore how body weight affects pregnancy outcom…

Ovarian endometriosis(OEM) is the most common type of endometriosis, but there is still a lack of simple and easy-to-promote animal models. Therefore, it is necessary to establish a feasible animal model of OEM and analyze its pathogenesis.…

OBJECTIVE: To explore the regulatory function and mechanism of CXCL14 in endometriosis. METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to examine the expression of CXCL14 in eutopic and ectopic endometrial str…

Increasing evidence suggests that non-coding small RNAs (miRNAs) carried by exosomes (EXOs) play important roles in the development and treatment of polycystic ovary syndrome (PCOS). In this study, we demonstrate that PCOS mouse serum-deriv…

BackgroundPolycystic 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 re…

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…

BackgroundThe 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.MethodsData were extracted from the SEER database for patients diagnosed…

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…

BackgroundDiabetes 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 as…

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…

BackgroundInfertility 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 r…

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…

ObjectiveTo explore the micro blood flow characteristics of normal singleton pregnancy placenta in middle and late pregnancy based on microvascular flow (MV-Flow) imaging.MethodsWe conducted a retrospective cohort study. Clinical records an…
