BackgroundThe incidence of malignant tumors/precancerous lesions is rising, yet their impact on pregnancy outcomes in women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) remains unclear.MethodsA single-center…

PurposeTo screen drug targets of ovarian aging from a genetic perspective.MethodsSystematic analyses were conducted with cis-expression quantitative trait loci data of druggable genes extracted as instrument variables. Summary statistics we…

Endometriosis (EMs) is a common gynecological disorder. According to the most widely recognized theory of retrograde menstruation, endometrial cells require completion of three key steps during ectopic implantation: adhesion, invasion, and …

IntroductionPrevious studies have indicated the association between smooth endoplasmic reticulum aggregates (SERa+) and poorer medically assisted reproduction outcomes. However, the link between SERa+ and neonatal outcomes remains controver…

Study questionDo extracellular vesicles (EVs) from human Fallopian tubes exert an influence on early embryo development in vitro?Summary answerHuman Fallopian tube EVs carrying miRNAs increase murine embryo viability in vitro.What is known …

OBJECTIVE: To investigate the association between different ovarian reserves and reproductive and adverse perinatal outcomes in patients with endometriosis. DESIGN: Retrospective study. SETTING: Reproductive Medicine Center in a hospital.…

OBJECTIVE: To investigate the influence of oviductal extracellular vesicles from patients with endometriosis on early embryo development. DESIGN: In vitro experimental study. SETTING: University-affiliated hospital. PATIENTS: Women with …

Kisspeptins, encoded by the KISS1 gene, are a family of polypeptides that bind the kisspeptin receptor (KISS1R) to perform biological functions. Produced mainly in the hypothalamus, these neuropeptides regulate the pulsatile secretion of Gn…

OBJECTIVE: To determine the optimal endometrial preparation protocol for a frozen embryo transfer in patients with endometriosis. DESIGN: Retrospective cohort study. SETTING: Tertiary care academic medical center. PATIENT(S): One thousan…

OBJECTIVE: To evaluate the effectiveness of ultra-long protocol on reproductive and controlled ovarian hyperstimulation outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) in infertile women with…

BackgroundTo minimize the rate of in vitro fertilization (IVF)- associated multiple-embryo gestation, significant efforts have been made. Previous studies related to machine learning in IVF mainly focused on selecting the top-quality embryo…

OBJECTIVE: This study aims to explore the differences of the ovarian stimulation (OS) characteristics, laboratory, and clinical outcomes between follicular-phase single-dose gonadotropin-releasing hormone (GnRH) agonist protocol and GnRH an…

This study measured the antioxidant activity of follicular fluid (FF) in infertile patients and assessed its possible correlation between ovarian stimulation and pregnancy outcomes. Samples from 191 infertile patients undergoing in vitro fe…
