The results of 30 consecutive microscopic vasovasostomy procedures performed at a single institution over a five-year period between 1991 and 1995 were reviewed. When the surgical outcomes of patients who were operated on less than five years after their vasectomy were compared with the outcomes of those patients who received a vasovasostomy more than five 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.
回顾了1991年至1995年期间在单一机构连续进行的30例显微输精管吻合术的结果。当比较输精管结扎术后不到五年接受手术的患者与输精管结扎术后五年以上接受输精管吻合术的患者的手术结果时，观察到技术成功率下降，表现为射精中出现精子（56%对36%）、生物恢复情况（平均精子计数5600万对3500万）和平均精子前向运动率（44%对21%），同时临床成功率也下降，以总体妊娠率衡量（50%对7%，p<0.05）。因此，输精管结扎术后5年内进行显微输精管吻合术是输精管复通的有利手术。
