BACKGROUND: Pelvic floor dysfunction (PFD) is a common cause of chronic constipation which can reciprocally exacerbate pelvic floor burden. However, the characteristics and evolution of pelvic floor structures in patients with constipation …

INTRODUCTION AND AIMS: Oral squamous cell carcinoma (OSCC) is a common malignant tumour of the head and neck region. In recent years, the relationship between pyroptosis and tumours has received increasing attention. However, its regulatory…

OBJECTIVE: High-intensity focused ultrasound (HIFU) therapy is increasingly used in the management of various solid tumors. However, limited data are available regarding the association between HIFU treatment and coagulation function. MATE…

OBJECTIVE: To investigate the complementary roles of rectal magnetic resonance imaging and endoscopic ultrasound in the preoperative assessment of rectal deep endometriosis (DE). DESIGN: Retrospective, cross-sectional study. SETTING: Shen…

OBJECTIVE: This study aimed to evaluate factors associated with the clinical pregnancy rate in women with diminished ovarian reserve (DOR) undergoing repeated assisted reproductive technology (ART) cycles. METHODS: A retrospective analysis…

BACKGROUD: Endometrial cancer (EC), the most prevalent gynecologic malignancy in developed countries, often arises from endometrial atypical hyperplasia (EAH). Thus, how to predict EAH combined with EC before total hysterectomy is particula…

A teenage girl presented with sudden lower abdominal pain following exercise, prompting initial consideration of ovarian cyst rupture by the attending emergency physician. However, the presence of unilateral renal absence on Computed Tomogr…

BACKGROUND: Recurrent implantation failure (RIF) is a major challenge in in vitro fertilization (IVF). The window of implantation (WOI) is the endometrium’s receptive period for embryos, and endometrial receptivity analysis (ERA) is a poten…

BACKGROUND Postoperative sleep disturbances are common after gynecological laparoscopic surgery, possibly delaying recovery. This study evaluated whether additional postoperative administration of dexmedetomidine hydrochloride nasal spray c…

BACKGROUND: In this study, we aimed to explore the effect of the timing of surgical management of hydrosalpinx on in vitro fertilization/intracytoplasmic single-sperm injection (IVF/ICSI) pregnancy outcomes in patients with tubal factor inf…

To investigate the efficacy of different pretreatment protocols for women with endometriosis undergoing IVF. We systematically searched the Cochrane Library, PubMed, Medline, and Embase from inception to April 30, 2025, to identify randomiz…

PURPOSE: Endometriosis often becomes symptomatic early in reproductive life, yet estimates for younger females are subsumed within broader reproductive-age populations. We assessed burden among females aged 15-29 years in China and the West…

BACKGROUND: Syndrome differentiation in Traditional Chinese Medicine (TCM) is pivotal to clinical practice and dictates the efficacy of medicinal treatments. However, precision diagnostic models for TCM syndromes, constructed from biomarker…

This study employed a multi-omics Mendelian randomization (MR) framework to identify exosome-related genes potentially associated with adenomyosis risk. We integrated adenomyosis Genome-Wide Association Study data with blood-based methylati…

Abdominal wall endometriosis is rare. Malignant transformation of abdominal wall endometriosis is extremely rare. We describe FDG PET/CT findings in a case of clear cell carcinoma arising from abdominal wall endometriosis with multiple lymp…

Fibroblast growth factor receptor 2 (FGFR2) has emerged as a highly promising therapeutic target due to its critical role in the pathogenesis and progression of endometriosis. To date, a variety of FGFR2 inhibitors have exhibited remarkable…

Oocyte/embryo defects can result in oocyte maturation arrest, fertilization failure, embryonic arrest, and infertility as well as recurrent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) failures. However, the genet…

BACKGROUND: Endometriosis is a common gynaecological disorder characterised by the ectopic growth of endometrial-like tissue, which can lead to clinical symptoms such as chronic inflammation, pelvic pain, and infertility. Aberrant cellular …

BACKGROUND: Despite their substantial global health impact, there has been no systematic and comprehensive evaluation of the epidemiological patterns and risk factors of pancreatitis and pancreatic cancer worldwide. This study aimed to quan…

Ovarian cancer is one of the most lethal gynecological malignancies globally, with significant variations in incidence, prevalence, and outcomes across regions and population subgroups. This study systematically evaluates the global, region…

When exploring the macro trend of declining global fertility rates, a pathological factor often hidden beneath individual suffering cannot be ignored: pelvic inflammatory disease (PID). Recurrent inflammation leads to tissue damage, adhesio…

BACKGROUND: Premature ovarian insufficiency (POI) significantly impairs female fertility and poses substantial health risks; however, its pathogenesis is incompletely understood, and effective therapeutic interventions are limited. Although…

This study aimed to investigate how levels of serum follicle-stimulating hormone (FSH) on Day 7 of ovarian stimulation are related to the number of oocytes retrieved, and identify any cutoff or threshold point in protocols using gonadotropi…

Biomarkers play a pivotal role in contemporary medical research, particularly in the early diagnosis of diseases and personalized treatment. Although previous studies have systematically reviewed markers across various disease domains, an i…
