OBJECTIVE: The study aims to elucidate the factors associated with the short-term efficacy of ovarian vein embolization (OVE) in the treatment of pelvic venous insufficiency (PVI), to construct a predictive model for short-term efficacy of …

BACKGROUND: Standardized residency training in obstetrics and gynecology (OB/GYN) relies heavily on Case-Based Learning (CBL). Yet, manually curating high-quality teaching cases remains a labor-intensive burden. OBJECTIVE: To develop and e…

OBJECTIVE: To evaluate the impact of day 4 double embryo transfer (DET) with a fully compacted morula (FCM) and a partially compacted morula (PCM) versus day 4 single embryo transfer (SET) with an FCM on clinical and neonatal outcomes in fr…

OBJECTIVE: The aim of this retrospective cohort study was to evaluate the clinical and neonatal outcomes between day 4 and day 5 embryo transfer across different fertilization methods. METHODS: This retrospective cohort study was conducted…

BACKGROUND: Adenomyosis, an estrogen-dependent condition characterized by endometrial invasion into the myometrium, is associated with reduced live birth rates and increased miscarriage risk in women undergoing assisted reproductive technol…

Ferroptosis is an iron-dependent form of programmed cell death driven by lipid peroxidation, distinct from apoptosis and necrosis. It has been confirmed as a key regulator in hepatocellular carcinoma (HCC). This study systematically elucida…

ObjectiveTo evaluate whether vitamin D supplementation improves live birth rates in women with polycystic ovary syndrome undergoing in vitro fertilisation.DesignMulticentre, double blind, placebo controlled, randomised clinical trial.Settin…

OBJECTIVE: To investigate the determinants affecting live birth outcomes in fresh embryo transfer among polycystic ovary syndrome (PCOS) patients using various machine learning (ML) algorithms and to construct predictive models, offering no…

BACKGROUND: The aim of this retrospective cohort study was to evaluate the effect of day 3 embryo cell number on the clinical pregnancy and neonatal outcomes of single blastocyst transfer in frozen embryo transfer (FET) cycles. METHODS: Th…

Abnormal development of granulosa cells is widely recognized as a critical factor contributing to polycystic ovary syndrome (PCOS). However, the precise etiology and underlying mechanisms of this disorder remain largely elusive. Accumulatin…

OBJECTIVE: Endometriosis increases ovarian cancer (OC) risk through genetic mutations, chronic inflammation, and hormonal dysregulation, yet the underlying molecular pathways remain underexplored. This study aims to identify endometriosis-a…

Mesenchymal cells constitute the primary structural support elements within endometriotic lesions, yet their pivotal roles in endometriotic pathogenesis remain largely uncharted. This study aimed to construct a single-cell atlas of endometr…

OBJECTIVE: To investigate the impact of changes in luteinizing hormone (LH) levels during ovulation induction using flexible gonadotropin-releasing hormone antagonist (GnRH-A) regimens in POSEIDON groups 1 and 2 on the clinical outcomes of …

OBJECTIVE: The study aims to elucidate clinical and ultrasonographic characteristics of female patients diagnosed with pelvic varicose veins (PVVs) and to assess potential risk factors associated with incidences of chronic pelvic pain (CPP)…

Endometrial collagen I undergoes dynamic degradation and remodelling in response to endometrial stromal cell (ESC) decidualization and embryo implantation. However, excessive collagen I deposition in the endometrium during the implantation …

BACKGROUND: The aim of this retrospective cohort study was to assess the impact of day 3(D3) embryo cell number on the clinical pregnancy and neonatal outcomes of day 4(D4) single embryo transfer in fresh cycles. METHODS: The study include…

OBJECTIVE: This study aims to investigate the effect of diminished ovarian reserve (DOR) on the clinical outcomes and maternal and infant safety of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) procedures in young women…

BACKGROUND: Ensuring women's sexual and reproductive health (SRH) is a fundamental human right and key to 2030 agenda of the UN Sustainable Development Goals (SDGs), yet limited evidence exists on SRH in China, including national estimates …

Uterine fibroids (UFs) are the most common benign gynecologic tumors in reproductive-aged women. The typical diagnostic strategies of UFs are transvaginal ultrasonography and pathological feature, while molecular biomarkers are considered c…

OBJECTIVES: Although in vitro fertilization with embryo transfer is the most effective treatment for infertile patients with endometriosis, ovarian stimulation protocols are controversial. STUDY DESIGN: We recruited 639 patients with endom…

OBJECTIVE: We compared the pregnancy and perinatal outcomes between expanded blastocysts vitrified on D5 versus D6 following single frozen blastocyst transfer. METHODS: Clinical data on 7,606 cycles of frozen-thawed blastocyst implantation…

PURPOSE: To construct and validate a nomogram model for predicting clinical pregnancy in individuals with endometriosis undergoing fersh embryo transfer (ET). METHODS: A retrospective analysis was conducted on 1630 individuals with endomet…

So far, ovarian cancer has still been the most lethal gynecological malignancy. The chemotherapy and targeted medication are the mainstay for the recurrent ovarian cancer treatment. About 70% of the advanced-stage cases will relapse. Ascite…

Endometrial decidualization is a decidual tissue formed by the proliferation and re-differentiation of endometrial stroma stimulated by decidualization inducing factors. It is very important for the proper maintenance of pregnancy. Previous…

Macrophages, as central components of innate immunity, feature significant heterogeneity. Numerus studies have revealed the pivotal roles of macrophages in the pathogenesis of liver fibrosis induced by various factors. Hepatic macrophages f…
