OBJECTIVES: The research aims to leverage machine learning techniques to better understand the diagnosis of myofascial pelvic pain syndrome (MPPS) and to develop useful tools for clinical practice. METHODS: This study retrospectively analy…

BACKGROUND: In assisted reproductive technology (ART) laboratories, semen processing is traditionally performed using manual density gradient centrifugation (DGC), which is labor intensive, time consuming, and subject to inter-technician va…

BACKGROUND: High-intensity focused ultrasound (HIFU), a noninvasive treatment method, has attracted increasing attention in recent years for the management of gynaecological diseases. This review summarizes current literature on the applica…

BACKGROUND: Little is known about the oncologic results of patients with low-grade endometrial stromal sarcoma (LGESS) with fertility preservation. This study investigated the prognosis of fertility-sparing surgeries and relevant obstetrica…

OBJECTIVE: This work aimed to evaluate the clinical value of serumanti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and transvaginal ultrasound (TVU) parameters in the diagnosis of ovarian reserve f…

STUDY OBJECTIVE: To explore the associations between adenomyosis patterns on transvaginal sonography (TVS) and surgical outcomes. DESIGN: A retrospective cohort study. SETTING: Peking Union Medical College Hospital, Beijing, China. PATIE…

BACKGROUND: Limited information is available on malpractice claims against obstetricians and gynecologists in China. This study identifies risk factors associated with malpractice and explores the correlation between the hospital characteri…

BACKGROUND: Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare congenital genital tract anomaly that severely impacts quality of life and fertility in female adolescents. Most of the publications on OHVIRA have …

BACKGROUND: Myofascial pelvic pain syndrome (MPPS) is a common but often underdiagnosed cause of chronic pelvic pain in women, significantly affecting quality of life. Early and accurate identification of patients at risk is essential for i…

BACKGROUND: Ovarian cancer is a highly lethal gynecological malignancy, with epithelial ovarian cancer (EOC) being its most common form. Surgery combined with chemotherapy is the standard treatment. Resection completeness significantly impa…

PURPOSE: The aim of this study was to summarize and analyze the incidence, underlying causes and related risk factors of misdiagnosis in patients with Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) syndrome. METHODS: This is …

High intensity focused ultrasound (HIFU) is an effective and safe non-invasive treatment method, widely used in the treatment of uterine fibroids and adenomyosis in the field of gynecology. The side effects in HIFU is low in incidence and m…

AIM: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) can improve long-term cardio-renal outcomes in patients with diabetes, heart failure (HF), or renal failure. We aimed to investigate the association of SGLT2is with the risks of vario…

AIMS: This study aims to reveal transcriptome-wide intronic polyadenylation (IPA) events associated with Pre-eclampsia (PE). BACKGROUND: Pre-eclampsia (PE) is a potentially life-threatening complication of pregnancy, affecting both materna…

OBJECTIVE: Little is known about the survival differences between uterine and extrauterine low-grade endometrial stromal sarcoma (LGESS). Survival outcomes, consisting of disease-free survivals and overall survivals (OS), were compared in t…

BACKGROUND: Laser-assisted hatching (LAH) stands as the predominant technique for removing the zona pellucida (ZP) in embryos, primarily consisting of two methods: drilling laser-assisted hatching (D-LAH) and thinning laser-assisted hatchin…

BACKGROUND: To assess the impact of the luteinizing hormone level on ovulation trigger day (LHOTD) on in vitro fertilization (IVF) outcomes in gonadotropin-releasing hormone (GnRH) agonist and antagonist regimens during fresh embryo transfe…

BACKGROUND: Vaccine hesitancy was found in couples seeking artificial reproductive technology (ART) services. As the main vaccine used in China, investigations into the influence of inactivated coronavirus disease 2019 (COVID-19) vaccines o…

EMs is a kind of benign disease with certain malignant behaviors. The adhesion, invasive growth, and angiogenesis of ectopic endometrial cells are the pathological basis of EMs occurrence, but its etiology and pathogenesis have not been com…

OBJECTIVE: To assess the impact of serum luteinizing hormone (LH) levels on the day of initiation of controlled ovarian stimulation (COS) after pituitary suppression on early pregnancy loss and assisted reproductive technology (ART) outcome…

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is a common condition in older women that affects quality of life. Mechanical injury of the pelvic floor support system contributes to POP development. In our study, we aimed to exami…

BACKGROUND: Patients with elevated circulating progesterone concentrations on the day of the human chorionic gonadotropin (hCG) trigger had relatively low implantation rates during assisted reproductive treatments. In this study, we assess …

e22517 Background: Uterine adenomyosis is a benign condition in which endometrium-like epithelial and stromal tissue appear in the myometrium, but easily concurrent with uterine cancer and other diseases. To date, few investigations have ex…

The uterine endometrium, which lines the mammalian uterus, is essential for embryo implantation. This lining undergoes significant changes during sexual and menstrual cycles. The endometrium is also associated with hormone-related diseases …
