Infertility remains a global challenge, with female factors accounting for the majority of cases. Endometrial receptivity (ER), the ability of the endometrium to accept and support embryo implantation, is a critical determinant of successfu…

Ovarian cancer, as a common gynecological malignancy, is often found at an advanced stage clinically. Thus, improving the early diagnosis of ovarian cancer is crucial for the survival rate of patients. Ultrasound examination is the main met…

BackgroundPelvic floor surface electromyography (sEMG) is widely used to evaluate and treat pelvic floor dysfunctions (PFDs). Based on sEMG, the Glazer protocol was developed over 20 years ago with a limited sample size, making it challengi…

BackgroundvNOTES has been documented as a viable approach for conducting benign gynecologic surgery; however, its application in ectopic pregnancy cases remains relatively scarce. The principal objective of this investigation was to assess …

To investigate the risk factors influencing very early preterm and early preterm births in twin pregnancies after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). This retrospective study analyzed 2042 twin pregnanc…

BackgroundInfertility poses a substantial societal and economic burden; however, current preventive strategies are limited. Recently, the relationship between gut microbiota and infertility has garnered increasing attention. The dietary ind…

BackgroundThis case-control study aimed to examine the association between the frequency of potentially risky beverage consumption, levels of anxiety, and the prevalence of endometrial polyps.MethodsA total of 418 participants were enrolled…

Endometriosis is an estrogen dependent disease, which is related to infertility. Decidualization is a prerequisite for successful implantation of human embryos, and endometriosis affects the occurrence of decidualization. However, the mecha…

Endometriomas, commonly known as ovarian chocolate cysts, are a prevalent condition in women of reproductive age. They are cysts formed by the ectopic growth of endometrial tissue within the ovary, often leading to dysmenorrhea and infertil…

Endometriosis is a complex, chronic inflammatory gynecological disorder with estrogen‑dependent characteristics that severely impairs the quality of life of women and potentially leads to infertility. However, its pathogenesis remains poorl…

BackgroundLimited 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 characterist…

BackgroundMyofascial 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 imp…

PURPOSE: To conduct a comparative metabolomic analysis of follicular fluid (FF) from patients undergoing in vitro fertilization (IVF) cycles under GnRH agonist versus antagonist protocols, aiming to identify protocol-specific metabolic sign…

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…

RESEARCH QUESTION: Does frozen embryo transfer improve pregnancy outcomes compared with fresh embryo transfer in women with ovarian endometriosis (OEM) undergoing their first IVF/intracytoplasmic sperm injection cycle? DESIGN: A retrospect…

PurposeTo investigate the effect of intraoperative low-dose esketamine administered at anesthesia induction on postoperative quality of recovery in total laparoscopic hysterectomy.Patients and methodsOne-hundred six female patients schedule…

Background and objectivePrimary dysmenorrhea carries substantial medical, social, and economic burdens, leading many patients to seek low-risk complementary and alternative therapies, such as acupuncture. Myofascial trigger point dry needli…

Killer-cell immunoglobulin-like receptor 2DL4 (KIR2DL4), a member of the killer cell immunoglobulin-like receptors (KIRs) family, plays an important role in the regulation of the immune system, which is expressed primarily on natural killer…

BACKGROUND: Intended to investigate the potential effects of endometrial preparation procedures on the results of subsequent frozen embryo transfer (FET) cycles in infertile women with chronic endometritis (CE) following a single course of …

BACKGROUND: Melatonin is mainly secreted by the pineal gland during darkness and regulates biological rhythms through its receptors in the suprachiasmatic nucleus of the hypothalamus. In addition, it also plays a role in the reproductive sy…

Research questionWhile growth hormone (GH) is hypothesized to potentially enhance embryo quality, results of current basic and clinical researches remain inconclusive. This study assesses the effect of GH supplementation on embryo quality a…

Cervical and ovarian cancers pose a significant global threat to women's health. Despite substantial medical advances in recent decades, gynecological malignancies remain a leading cause of female mortality, constrained by factors such as m…
