A prospective randomized trial comparing Cook K-SOFT-5100 and Frydman classical catheter 4.5 for embryo transfer in human IVF/ICSI was performed. Three experienced operators participated in the trial, using a fixed distance transfer protocol. Primary endpoint was clinical pregnancy rate, secondary endpoints were rates of difficult transfer and of catheter failure. Patients were randomized by a computer program immediately prior to embryo transfer.
