Objective To compare pregnancy and implantation rates with transvaginal (TV) versus transabdominal (TA) ultrasound-guided embryo transfer (ET). Design Randomized, clinical trial registered at clinicaltrials.gov (NCT 01137461). Setting Private, infertility clinic. Patient(s) Three-hundred thirty randomized recipients of donor oocytes. Intervention(s) Embryo transfer using TV (with empty bladder, using the Kitazato ET Long catheter) versus TA ultrasound guidance (with full bladder, using the echogenic Sure View Wallace catheter). Main Outcome Measure(s) Overall pregnancy, clinical pregnancy, implantation, and ongoing pregnancy rates. Duration and difficulty of ET. Patient-reported uterine cramping and discomfort, as evaluated by questionnaire. Result(s) No statistically significant differences were observed in clinical pregnancy 50.9% versus 49.4% (95% confidence interval of the difference: -9.2 to +12.2%), implantation 34.5% versus 31.4% (95% CI of the difference: -4 to +10.3%) between the TV and TA ultrasound-guided groups. Transfer difficulty (6% versus 4.2%) and uterine cramping (27.2% versus 18.3%) were not statistically significantly different between treatment groups. Total duration (154 ± 119 versus 85 ± 76 seconds) was statistically significantly higher in the TV ultrasound group. Light to moderate-severe discomfort related to bladder distension was reported by 63% of the patients in the TA ultrasound group.
