Ultrasound‑assessed endometrial receptivity measures for the prediction of in vitro fertilization‑embryo transfer clinical pregnancy outcomes: A meta‑analysis and systematic review

At present, there are currently no reliable and consistent conclusions regarding transvaginal ultrasound assessment of endometrial receptivity in predicting clinical pregnancy outcomes in vitro fertilization‑embryo transfer (IVF‑ET). Thus, the present study, a meta‑analysis was performed on multiple indices detected by vaginal ultrasound, aiming to provide diagnostic basis for practice. PubMed, Embase, Cochrane Library databases were searched studies published between establishment through January 2023. Studies that reported infertile women undergoing IVF‑ET included, but repeat publication, where full text not obtainable, incomplete information provided or data extraction possible, animals, case reports, reviews, systematic reviews excluded. STATA 15.1 used analyze data. The pooled results showed thickness [Weighted mean difference (WMD)=0.03, 95% CI: 0.00‑0.06; P=0.022] volume (WMD=0.41, 0.07‑0.74; P=0.017) group after receiving all significantly higher than non‑pregnancy group. also vascularization index (VI) (WMD=0.79, 0.56‑1.03; P=0.000), flow (FI) (WMD=1.82, 0.83‑2.81; P=0.000) (VFI) (WMD=1.58, 0.91‑2.24; Systolic/diastolic (S/D) (WMD=‑4.92, 95%CI: ‑8.28‑ ‑1.56; P=0.004) uterine artery lower However, differences resistance (RI) pulsatility (PI) vs. statistically significant.
