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…

BACKGROUND: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been shown to disrupt normal follicular development and ovulation. However, it is unknown which specific PFAS in follicular fluid negatively impact oocyte development and…

BACKGROUND: Although the dietary inflammatory index (DII) plays a vital role in human health, the association between the DII and women's menopausal status is still unclear. The aim of this study was to investigate the associations of the e…

INTRODUCTION: A potential association between periodontitis and endometriosis has been indicated in previous observational studies. Nevertheless, the causal link between these two disorders has not been clarified. METHODS: Based on publicl…

Recently, increasing numbers of studies have demonstrated that transient receptor potential ankyrin 1 (TRPA1) can be used as a potential target for the treatment of inflammatory diseases. TRPA1 is expressed in both neuronal and non-neuronal…

OBJECTIVES: The present research aimed at clarifying the role played by miR-27a in the context of intrauterine adhesion (IUA) by focusing on its impact on TGFβ1-induced epithelial-mesenchymal transition (EMT), migration, oxidative stress, a…

Embryo selection in in vitro fertilization-embryo transfer (IVF-ET) mostly relies on morphological assessment using a conventional microscope or the time-lapse monitoring system, which is not comprehensive. Inappropriate levels of reactive …

BACKGROUND: Frozen-thawed embryo transfer (FET) is thought to be associated with obstetric and neonatal complications after in vitro fertilization/intracytoplasmic single sperm injection (IVF/ICSI) treatment. The study aimed to determine wh…

BACKGROUND AND AIM: Research has shown that green tea catechins may influence the activity of drug metabolizing enzymes and drug transporters. We examined whether epigallocatechin-3-gallate (EGCG) affected the pharmacokinetics and pharmacod…

INTRODUCTION: The time-lapse imaging system (TLS) is a newly developed non-invasive embryo assessment system. Compared with conventional incubators, a TLS provides stable culture conditions and consistent observations of embryo development,…

BACKGROUND: To evaluate the diagnostic performance of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) for ovarian cancer. PATIENTS AND METHODS: A thorough research was conducted in PubMed, Web of…

BACKGROUND: The red cell distribution width (RDW) has attracted attention in the diagnosis of malignant tumors. In this study, we analyzed the correlation between the RDW and ovarian cancer by observing changes in the RDW in patients with o…

OBJECTIVE: To investigate the clinical efficacy of laparoscopic repair of iatrogenic vesicovaginal fistulas (VVF) and rectovaginal fistulas. METHODS: Seventeen female patients with iatrogenic fistulas (11 cases of VVF and 6 cases of high r…

Objective To describe the appearance of various endometriotic lesions under laparoscope and their histological characteristics, and to explore the process of implanted endometrial debris. Methods 58 infertile women were examined by laparosc…

OBJECTIVE: To study the optimal position and method for ovarian transposition and its benefits and indications. METHODS: We performed ovarian transposition in 34 patients from August 1989 to December 2000. Twelve patients were diagnosed wi…
