Uterine mechanical properties, particularly tissue stiffness, are dynamically regulated during the embryo implantation window to ensure optimal mechanocompatibility. However, maternal aging and fibrotic pathologies, such as adenomyosis and …

BACKGROUND: Optimal endometrial thickness and receptivity, precisely regulated by steroid hormones, are critical determinants for successful embryo implantation. Thin endometrium is a major cause of female infertility, yet its pathogenesis …

BackgroundCompared with overnight insemination, it remains uncertain whether short-term insemination can improve outcomes in poor responders, and few studies have used cumulative live birth rate as the primary endpoint. The study aims to co…

Sleep deprivation (SD) is a significant risk factor for reproductive dysfunction. This review aims to synthesize evidence establishing that oxidative stress (OS) is the key pathological mediator of SD-induced reproductive impairments in bot…

BACKGROUND: Cervical pregnancy (CP) is a rare but life-threatening ectopic gestation with high risk of catastrophic hemorrhage during evacuation. Uterine artery embolization (UAE) combined with dilation and curettage (D&C) has been proposed…

PurposeTo compare the clinical outcomes of extremely poor responders with one or two oocytes who receive in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).MethodsA retrospective study was carried out on 2572 patients …

ObjectiveThis prospective study aimed to investigate the short-term effects of single-port laparoscopic hysterectomy for benign conditions on postoperative pelvic floor symptoms, pelvic floor structure, and pelvic floor muscle function.Stud…

Mixed epithelial and stromal tumor (MEST) of the kidney is a rare benign neoplasm composed of both stromal and epithelial components. MEST is mainly seen in adults with a strong predilection for perimenopausal women with history of hormone …

While the link between female reproductive function and cardiovascular health (CVH) is well-established, the association between pelvic inflammatory disease (PID) and CVH remains largely unexplored. This study, therefore, sets out to fill t…

BackgroundLow-dose aspirin is one of the widely used adjuvants in assisted reproductive technologies with the hope of improving the live birth rate. However, the studies regarding its effects are conflicting. The study aimed to investigate …

PurposeTo evaluate the contribution of the cleavage stage morphological parameters to the prediction of blastocyst transfer outcomes.MethodsA retrospective study was conducted on 8383 single-blastocyst transfer cycles including 2246 fresh a…

OBJECTIVES: We aimed to explore the epidemiological characteristics of suspected adenomyosis within a physical examination population in China. DESIGN: A retrospective, nested case-control study; we matched healthy people and those with po…

To identify credible causal risk variants (CCVs) associated with different histotypes of epithelial ovarian cancer (EOC), we performed genome-wide association analysis for 470,825 genotyped and 10,163,797 imputed SNPs in 25,981 EOC cases an…

Thin endometrium (TE) is a significant factor contributing to fertility challenges, and addressing this condition remains a central challenge in reproductive medicine. Menstrual blood-derived mesenchymal stem cells (MenSCs) play a crucial r…

During embryo implantation, blastocyst interacts with the receptivity endometrium and the endometrial epithelium secretes nurturing fluid to support embryonic development. Interferon-λ (IFN-λ) is a novel, non-redundant regulator that partic…

ObjectiveTo investigate whether using Zishen Yutai Pills (ZYP) following embryo transfer would affect the live birth rate in frozen-thawed embryo transfer (FET) cycles.MethodsA retrospective analysis was performed on 15044 FET cycles in the…

Study questionWhat was the performance of different pretreatment prediction models for IVF, which were developed based on UK/US population (McLernon 2016 model, Luke model, Dhillon model, and McLernon 2022 model), in wider populations?Summa…

There is limited research on risk factors for chronic endometritis regarding reproductive history and clinical symptoms. Thus, this nested case-control study identified risk factors for chronic endometritis in women who have undergone hyste…

The microenvironment of the endometrial immune system is crucial to the success of placental implantation and healthy pregnancy. However, the functionalities of immune cells across various stages of the reproductive cycle have yet to be ful…

BackgroundLaser-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 hatching …

BackgroundBronchopulmonary dysplasia (BPD) is the most challenging chronic lung disease for prematurity, with difficulties in early identification. Given lncRNA emerging as a novel biomarker and the regulator of ferroptosis, this study aims…

Infertility is a worldwide reproductive health problem and there are still many unknown etiologies of infertility. In recent years, increasing evidence emerged and confirmed that epigenetic regulation played a leading role in reproduction. …

BackgroundOocyte degeneration was mostly described in intracytoplasmic sperm injection (ICSI) cycles; there is no report showing the relationship between oocyte degeneration and clinical outcomes in conventional in vitro fertilization (IVF)…

Background: Male and female gametes factors might contribute to the total fertilization failure (TFF). In first in vitro fertilization (IVF) cycles, decision-making of insemination protocol was mainly based on semen quality for the contribu…

Female fertility declines with age, and this natural variation culminates in reproductive senescence. Human follicular fluids are rich in low-molecular weight metabolites which are responsible for the maturation of oocytes. The metabolomic …
