Endometrial cancer (EC) encompasses various histological and molecular subtypes, each with unique immune, endocrine and metabolic characteristics, resulting in varying responses to treatment. Although immunotherapy, endocrine therapy and me…

Recurrent implantation failure (RIF), characterized by repeated failure to achieve clinical pregnancy after embryo transfer, is often associated with abnormal endometrial conditions. However, unexplained RIF is unique in that its underlying…

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…

ObjectiveTo investigate the impact of three endometrial preparation protocols-hormone replacement therapy (HRT), natural cycle (NC), and down-regulation HRT-on pregnancy outcomes in frozen embryo transfer (FET) cycles among patients with a …

ObjectiveTo investigate the effect of Tiao-Jing-Cu-Yun Acupuncture on pregnancy outcomes in infertility patients with thin endometrium undergoing artificial cycle frozen-thawed embryo transfer (AC-FET).MethodsA prospective, assessor-blinded…

BACKGROUND: Endometriosis (EMS), a well-recognized chronic inflammatory disorder, characterized by significant immune dysregulation, in which myeloid-derived suppressor cells (MDSCs) are essential for facilitating immunosuppression and driv…

As a complex chronic gynecological disorder characterized by multifaceted etiology involving genetics, environment, immunity and inflammation, endometriosis (EM) has long been a significant concern for women of reproductive age worldwide. T…

In couples with of non-male factor infertility, prevailing discussions have focused primarily on patients undergoing fresh embryo transfer. However, whether intracytoplasmic sperm injection (ICSI) improves reproductive outcomes in patients …

OBJECTIVE: To evaluate the P2X3 receptor antagonist, gefapixant, for treating moderate-to-severe endometriosis-related pain. DESIGN: Randomized, double-blind, phase 2, and proof-of-concept trial. SUBJECTS: Premenopausal women age 18-49 ye…

Metal ions-based regulated cell death (RCD), a form of cell death involving metal ions and controlled by one or more cascade signaling pathways, has recently been termed "metalloptosis". Given the rapid advances in understanding metalloptos…

ObjectiveTo explore the correlation between antinuclear antibodies (ANAs) and pregnancy loss (PL), and to observe its impact on the pregnancy outcomes of in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) …

ObjectiveThe objective was to analyze the impact of the uterine artery pulsatility index (PI) on pregnancy outcomes by measuring uterine artery blood flow on the day of endometrial transformation in patients undergoing frozen-thawed embryo …

BackgroundDue to the high risk of complications in fresh transfer cycles among expected high ovarian response patients, most choose frozen-thawed embryo transfer (FET). There are currently few researches on whether the FET outcomes of expec…

OBJECTIVES: The objective of this study was to investigate the glycolytic activity of adenomyosis, which is characterized by malignant biological behaviors including abnormal cell proliferation, migration, invasion, cell regulation, and epi…

Colonization of the vaginal space with bacteria such as Gardnerella vaginalis and Mobiluncus mulieris is associated with increased risk for STIs, bacterial vaginosis, and preterm birth, while Lactobacillus crispatus is associated with optim…

ObjectiveWe investigated whether the addition of a luteal phase support drug benefits pregnancy and perinatal outcomes in modified natural-cycle frozen-thawed embryo transfer (mNC-FET) for women up to the age of 35 years.MethodsWe analyzed …

The adverse effect of ambient PM2.5 exposure on very early pregnancy (VEP) remains controversial among epidemiological studies but is supported by toxicological evidence. We adopted a multicenter retrospective cohort of 141,040 cycles to ev…

OBJECTIVE: To investigate the expressions of glycolysis-related factors and changes in Notch1 signaling in endometrial tissues of adenomyosis (AM) and Ishikawa cells to explore the pathogenesis of AM. METHODS: Eutopic endometrial tissues w…

PurposeTo explore the risk and protective factors for developing ovarian cancer and construct a risk prediction model.MethodsInformation related to patients diagnosed with ovarian cancer on the electronic medical record data platform of thr…

Background/objectiveThis study aimed to investigate the causal relationship between urate level and female infertility using Mendelian randomization (MR) analysis.MethodsTo identify instrumental variables, we selected independent genetic lo…

BackgroundOne potential cause of implantation failure is abnormal endometrial receptivity, and how to objectively evaluate endometrial receptivity has been a matter of great concern. Endometrial receptivity analysis (ERA), a next-generation…

Heart and neural crest derivatives expressed transcript 2 (HAND2) is a critical mediator of progesterone action in endometrial stromal cells. Silencing of Hand2 expression in mouse uterus leads to an unopposed FGFR-mediated action that caus…

BACKGROUND: Previous studies have reported that after laparoscopic cystectomy of ovarial endometrioma, the ovarian response to gonadotropin (Gn) significantly decreased. However, for patients with diminished ovarian reserve (DOR) after ovar…

ObjectiveTo explore the cumulative outcomes and influencing factors of patients with discrepancies between age and Anti-Müllerian hormone (AMH) levels in the early follicular phase prolonged protocol.MethodsA total of 1282 cycles of in-vitr…

This retrospective case-control study examined the association between the rs2071559 (-604T/C) single nucleotide polymorphism (SNP) in the vascular endothelial growth factor receptor (VEGFR)-2 gene and the risk of diabetic retinopathy (DR) …
