SURGICAL OUTCOME OF MICROSCOPIC VASECTOMY REVERSAL: AN ANALYSIS OF 30 CASES

The results of 30 consecutive microscopic vasovasostomy procedures performed at a single institution over a 5-year period between 1991 and 1995 were reviewed. When the surgical outcomes of patients who were operated less than 5 years after their vasectomy were compared with the outcomes of those patients who received a vasovasostomy more than 5 years after their vasectomy decreases in technical success rates were observed as measured by appearance of sperm in ejaculate (56% vs. 36%) biologic recovery as measured by mean sperm counts (56 million vs. 35 million) and mean progressive sperm motility (44% vs. 21%) along with a decrease in clinical success as measured by overall pregnancy rates (50% vs. 7% p < 0.05). Therefore a microscopic vasovasostomy within 5 years of a vasectomy is a favorable procedure for vasectomy reversal. (authors)
