BACKGROUND: Repeated implantation failure (RIF) remains a significant challenge in assisted reproductive technology. Endometrial receptivity (ER) plays a critical role in embryo implantation. However, the impact of advanced maternal age (AM…

BACKGROUND: The ovary is a vital and dynamic reproductive organ. Ovarian tissue cryopreservation (OTC) plays a vital role in preserving female fertility. However, the cellular subtypes most susceptible to cryoinjury and the molecular mechan…

STUDY QUESTION: Do novel per- and poly-fluoroalkyl substances (Novel PFAS) have associations with premature ovarian insufficiency (POI)? SUMMARY ANSWER: Hexafluoropropylene oxide dimer acid (HFPO-DA), perfluorobutanoic acid (PFBA), perfluo…

OBJECTIVE: This study aimed to investigate the causal relationship between dietary habits and nine common diseases with high female prevalence using a two-sample Mendelian randomization (MR) approach. METHODS: Drawing upon pooled Genome-Wi…

OBJECTIVE: While physical activity (PA) patterns are epidemiologically linked to gynecologic pathologies, establishing causality remains uncertain. This Mendelian randomization (MR) study evaluated causal relationships between PA phenotypes…

ABSTRACT: The effectiveness of the GnRH antagonist protocol remains controversial due to inconsistent conclusions and inadequate subgroup analyses. The aim of this study was to provide some references for clinicians when choosing the GnRH a…

Mercury, a prevalent heavy metal, negatively impacts oocyte maturation. However, the exact mechanism by which methylmercury chloride (MMC) affects this process remains elusive. The present study found that MMC administration triggered meiot…

BACKGROUND: Ulcerative colitis (UC) is an agnogenic chronic intestinal inflammatory disease. Umbilical cord-derived mesenchymal stem cell (UMSC) is a potential therapeutic approach against UC; however, the mechanisms underlying their effica…

The most common medications for the treatment of zoonotic toxoplasmosis are pyrimethamine and sulfadiazine, which may cause serious undesirable side effects. Thus, there is an urgent need to develop novel therapeutics. Baicalein (BAI, C15H1…

OBJECTIVE: To explore the biological relationship between the regulatory signal pathways involved in differentially expressed genes and recurrent spontaneous abortion (RSA) by analyzing the gene expression microarray data of unexplained RSA…

BACKGROUND: Polycystic ovary syndrome (PCOS), an incidence of 10-15% in women of reproductive age, shows sex hormone disorders, luteal insufficiency, and the tendency of placental villus space thrombus. The incidence of early pregnancy loss…

BACKGROUND: There is evidence for an association between the gut microbiome and endometriosis. However, their causal relationship and the mediating role of lipid metabolism remain unclear. METHODS: Using genome-wide association study (GWAS…

STUDY OBJECTIVE: To evaluate the efficacy and pregnancy outcomes of intrauterine balloon and intrauterine contraceptive devices in the prevention of adhesion reformation following hysteroscopic adhesiolysis in infertile women with moderate …

Ovarian cancer (OC) represents the most prevalent malignancy of the female reproductive system. Its distinguishing features include a high aggressiveness, substantial morbidity and mortality, and a lack of apparent symptoms, which collectiv…

This study aims to construct and validate a nomogram for the differential diagnosis of ovarian endometriosis cyst versus ovarian cystadenoma. We retrospectively studied the clinical characteristics of patients with ovarian endometriosis cys…

INTRODUCTION: Nucleotide-binding domain (NOD)-like receptors (NLRs) are expressed in the endometrium, and involved in modulating the female innate immune responses. There are conceptus-endometrial interactions during pregnancy, which ensure…

BACKGROUND: Polycystic ovary syndrome (PCOS) affects 6-20% of women worldwide, with insulin resistance and hyperinsulinemia occurring in 50-70% of patients. Hyperinsulinemia exacerbates oxidative stress, contributing to PCOS pathogenesis. N…

The decrease in assisted reproductive technology success among older women, attributed to decreased oocyte quantity and quality, poses a significant challenge. Currently, no consensus on the optimal ovarian stimulation protocol for older wo…

Background: The SARS-CoV-2 virus is continually evolving, and the worldwide epidemic is still ongoing. There is conflicting evidence regarding how SAS-CoV-2 infection affects the outcomes of assisted reproductive technology (ART). The aim …

AIMS: M2 macrophage is believed to play an important role in the development of endometriosis. This study aimed to identify several key genes related to the M2 macrophage in endometriosis. METHOD: Differential expressed genes between endom…

M2 macrophage is believed to play an important role in the development of endometriosis. This study aimed to identify several key genes related to the M2 macrophage in endometriosis. Differential expressed genes between endometriosis and no…

BACKGROUND: It has been reported that the use of glucocorticoids may be able to improve clinical pregnancy rates in patients receiving in vitro fertilization and embryo transfer (IVF-ET). The purpose of this study was to investigate the ass…

It has been reported that the use of glucocorticoids may be able to improve clinical pregnancy rates in patients receiving in vitro fertilization and embryo transfer (IVF-ET). The purpose of this study was to investigate the association bet…

OBJECTIVES: To investigate the incidence of functional ovarian cysts, its influence on clinical rates, and proper management after depot gonadotropin-releasing hormone (GnRH) agonist pretreatment in artificial frozen-thawed embryo transfer …
