Does transabdominal ultrasound-guided embryo transfer improve pregnancy rates in ART cycles?

Background: recent reports have suggested that ultrasound-guided embryo transfer(ug-et) might improve pregnancy rates.objective: to determine whether transabdominal ug-et is a useful tool for increasingpregnancy and implantation rates in patients undergoing ivf or icsi.materials and methods: a prospective randomized clinical trial was conducted in 180patients in order to compare embryo transfer under abdominal ultrasound-guidance(n=90) with embryo transfer by clinical touch method (n=90).results: the clinical pregnancy rate was 21.1 % in the ultrasound-guided group and15.5 % in the clinical touch group (p =0.3). the implantation rate in the ultrasoundguided group was 11.1% while this was 7.2% in the clinical touch group (p =0.12). thepercentage of difficult transfer was not significantly different in both groups, this was8.9% in the ultrasound-guided group and 13.3% in the clinical touch group (p =0.47).conclusions: although the clinical pregnancy and implantation rate are higher in ugetgroup than the clinical touch group, but this difference was not statisticallysignificant. ultrasound-guided embryo transfer (ug-et), pregnancy rate, art.
