The echoguide embryo transfer maximizes the IVF results.

The performance of two different methods of embryo transfer for IVF has been evaluated in 132 consecutive embryo transfers. Thirty Eight pregnancies were achieved, corresponding to a pregnancy rate of 28.7% of all embryos transfers. The embryo transfer under ultrasound control was used in 61 cases of our study whereas 71 cases were performed with the "clinical feel" method without ultrasound control. The echoguide embryo transfer procedure yielded a significantly higher pregnancy rate than the blind method (36.06% versus 22.6%). The mean number of embryos transferred per attempt was similar in the two groups (3.1 +/- 0.1 and 3.0 +/- 0.1) as was the quality. The randomized comparative study will continue in order to get more data.
