Vasovasostomy: comparison of two microsurgical techniques.

An easier technique of microsurgical vasovasostomy, a modified one-layer anastomosis, is compared to double-layer anastomosis. In this preliminary report there is no difference between the modified one-layer and double-layer techniques in per cent of patients postoperatively obtaining normal sperm count and pregnancy. Since the modified one-layer technique is easier, faster, and less expensive, this technique deserves further clinical experience and evaluation.
