Microscopic technique for reversal of vasectomy.

This microscopic technique for reversal of a vasectomy requires intensive training on small animals in the laboratory before it can be attempted on humans. It has assured sperm in the ejaculate of all patients who have sperm in the proximal portion of the vas at the time of vasovasostomy, good sperm count and motility three to five months later in 90 per cent of them and early pregnancy of the spouse in 50 per cent. Longer follow-up periods will be necessary to estimate how high the eventual success rate will be, but it appears at this juncture that this approach is preferable to nonmicroscopic splinting techniques.
