BackgroundThe weekend effect is a controversial epidemiological phenomenon that has rarely been reported in the assisted reproductive technology (ART) setting, particularly among first-cycle fresh embryo transfer (ET) populations undergoing…

PurposeThis study aims to establish a single-time point RNA-sequencing-based endometrial receptivity test (rsERT) to provide hourly precision of endometrial WOI for patients with recurrent implantation failure (RIF).MethodsA two-phase study…

In this single-center, double-blinded, randomized controlled trial, we investigated whether human umbilical cord-derived mesenchymal stromal cells loaded collagen scaffolds (hUC-MSC/CS) could improve the cumulative live-birth rate (cLBR) in…

To evaluate whether the Spring Festival has an effect on the outcomes of patients undergoing their first embryo transfer (ET) via in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). We conducted a retrospective cohort study …

OBJECTIVE: To systematically review studies on reproductive outcomes following fertility-sparing interventions. METHODS: Various electronic databases were searched and studies reporting reproductive outcomes following fertility-sparing int…

PurposeTo investigate whether personalized embryo transfer (pET) predicted by a modified RNA-sequencing-based endometrial receptivity test (rsERT) model can improve intrauterine pregnancy rate (IPR) in patients with a receptive window of im…

BackgroundThe study investigated whether specific ultrasonographically observed endometrial features (including endometrium type and thickness) were linked to ectopic pregnancy after stimulated cycles with fresh embryo transfer.MethodOf 624…

BackgroundThere has been an interest in the relationship between ABO blood groups and infertility. Many studies have investigated the association of ABO blood groups with diminished ovarian reserve (DOR), ovarian hyperstimulation syndrome (…

BackgroundWindow of implantation (WOI) displacement is one of the endometrial origins of embryo implantation failure, especially repeated implantation failure (RIF). An accurate prediction tool for endometrial receptivity (ER) is extraordin…

Epithelial-mesenchymal transition (EMT) induced by estrogen contributes to the development of adenomyosis. However, the exact underlying mechanism remains mostly obscure. We hypothesized that a transmembrane glycoprotein neuropilin 1 (NRP1)…

Uterine peristalsis plays a vital role in fertility and female reproductive health. Although uterine peristalsis is thought to be correlated with some hormones and uterine pathologies, the physiological mechanisms underlying uterine perista…

BackgroundThere is much value in identifying non-invasive ways of measuring endometrial receptivity, as it has the potential to improve outcomes following in vitro fertilization (IVF). It has been suggested that endometrial echogenicity on …

OBJECTIVE: Bone mesenchymal stem cells (BMSCs) transplantation has a therapeutic effect on the thin endometrium in animal researches and clinical trials. The present study aims at assessing whether transplantation of VEGF-transfected BMSCs …

STUDY QUESTION: Is there a relationship between severe teenage acne and endometriosis? SUMMARY ANSWER: Endometriosis is positively associated with severe teenage acne. WHAT IS KNOWN ALREADY: No studies have specifically explored a possible …

STUDY QUESTION: What is the effect of uterine peristalsis on fluid migration after mock embryo transfer? SUMMARY ANSWER: Uterine peristaltic wave frequency was positively correlated with the distance that fluid moved after it was deposited …

STUDY QUESTION: Is there a difference in the characteristics of uterine peristalsis in natural and controlled ovarian hyperstimulation (COH) cycles? SUMMARY ANSWER: COH significantly changed the uterine peristaltic pattern. WHAT IS KNOWN AL…

BACKGROUND: To study the effect of endometrial thickness and pattern measured using ultrasound upon pregnancy outcomes in patients undergoing IVF-ET. METHOD: One thousand nine hundred thirty-three women undergoing IVF treatment participated…

OBJECTIVE: To examine the association among malondialdehyde (MDA), superoxide dismutase (SOD) and incidence of apoptosis of granulosa cells in follicular fluid with the outcome of in vitro fertilization-embryo transfer (IVF-ET). METHODS: W…

Objective: To evaluate the efficacy of transvaginal puncture guided by ultrasound combined with gonadotropin releasing hormone agonist (GnRH-a) in the treatment of endometrial cystoma of ovary. Methods: 58 cases of patients who were clinica…
