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.

New therapeutic possibilities handling residual azoospermia.

Obviously, medical therapy of secretory azoospermia or microsurgical therapy of excretory azoospermia are not always successful. The unsolvable cases therefore can be grouped as residual azoospermias. Both the medical and microsurgical approaches are reviewed and their success rates analyzed. Some problems are unsolvable after work-up of the diagnosis. Till the early nineties, such patients were discouraged to undergo further medical therapeutic approaches and were advised to consider either adoption or donor insemination. At the present time, new possibilities have risen since the use of epididymal spermatozoa for performing assisted fertilization has considerably altered the picture. Furthermore, the last breakthrough of using testicular spermatozoa combined with the ICSI procedures have offered solutions that were unthinkable only a few years ago. The impact of these new approaches is discussed and the future development of microsurgery versus assisted reproduction techniques is also considered.
