BACKGROUND: The 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 undergoi…
PURPOSE: This 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). METHODS: A two-phase…
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 …
PURPOSE: To evaluate whether the inflammatory proteomics of uterine fluid is feasible in defining the endometrial receptivity phase. METHODS: Inflammatory proteomics of uterine fluid was measured using the OLINK Target-96 Inflammation pane…
BACKGROUND: To evaluate the risk factors associated with WOI (window of implantation) displacement based on ERT (endometrial receptivity test), and to confirm the association of ectopic pregnancy with WOI displacement. METHODS: This is a r…
PURPOSE: To 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 …
BACKGROUND: The 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. METHOD: …
BACKGROUND: Embryo implantation in a receptive endometrium is crucial for successful pregnancy. Endometrial receptivity (ER) prediction tools based on endometrial transcriptome biomarkers by endometrial biopsy have been used to guide succes…
BACKGROUND: Whether pretreatment with gonadotropin-releasing hormone agonist (GnRHa) can improve the pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles is controversial. The inconsistencies in the results of different studies …
INTRODUCTION: Endometrium characteristics that are most likely to induce ectopic pregnancy were investigated on the basis of the data of 5,960 pregnant freeze-thaw cycles. METHODS: A total of 5,960 pregnancy cycles after freeze-thaw embryo…
BACKGROUND: GnRH agonist (GnRHa) pretreatment before the frozen-thawed embryo transfer (FET) was increasingly utilized. However, the incidence of GnRHa-induced functional ovarian cysts (FC) was inevitable. The feasibility and efficacy of HC…
OBJECTIVE: To evaluate the associations between homeostatic model assessment for insulin resistance (HOMA-IR) and pregnancy outcomes in non-dyslipidemic infertile women undergoing in vitro fertilization/intracytoplasmic sperm injection-embr…
BACKGROUND: Whether MTHFR C677T genotype affects pregnancy outcomes following assisted reproductive technology is conflicting. And the role of MTHFR C677T genotype on cumulative live birth has not been reported. This study aims to investiga…
BACKGROUND: Poor endometrial receptivity is a major factor that leads to recurrent implantation failure. However, the traditional method cannot accurately evaluate endometrial receptivity. Various studies have indicated that microRNAs (miRN…
Integrin β3 (ITGB3), which is the target gene of the miRNA let-7 that can be antagonized by long noncoding RNA (lncRNA) H19, is well known to have a critical role in endometrium receptivity. However, the regulation of ITGB3 in cell-cell or …
