The frequency of vasovasostomy has increased dramatically in recent years. A significant percentage of men who have previously undergone vasectomy are now seeking restoration of their fertility. The most common reason for requesting a reversal is remarriage. There were 90 bilateral vasovasostomies performed in 90 patients between 1986 and 1989. The procedure was done according to the technique described by Howards, in a single layer with 7 x 0 prolene and under fourfold magnification. The success rate was 87% for presence of spermatozoa in the ejaculate, 48% for pregnancy. The fertility rate decreases slowly with increasing interval between vasectomy and reanastomosis. These results are statistically significant. In cases of good anatomical and andrological conditions, the chance of restoration of fertility is good. The experience of the urologist is often more important than the details of the technique.
