To determine whether the use of abdominal ultrasound-guided embryo transfer improves the clinical pregnancy rate in patients undergoing in vitro fertilization, 50 fresh cycles with day 3 embryo transfer were studied; 27 patients were randomized to ultrasound-guided transfers, and 23 patients were randomized to clinical touch transfers. Although the clinical pregnancy rate was not statistically different (18.5% in the ultrasound-guided group vs. 17.4% in the clinical touch group), the use of abdominal ultrasound during the embryo transfer procedure provided a greater degree of confidence and satisfaction to both patients and physicians.
