Excellent results of vasectomy reversal have been reported by Silber and Owen in 1977 using microsurgical technique without splints. Herein, we report two cases of male sterility due to previous voluntary vasectomy in which fertility was restored by microsurgical vasovasostomy. The reason for vasectomy reversal in these cases was a subsequent marriage. Case 1: A 36-year-old male who had had vasectomy 3 years earlier, underwent vasovasostomy on September 20th 1976. The sperm granuloma was not found, but sperm was observed in the fluid from the proximal cut-end of the vas deferens at the time of operation. He fathered a baby on October 2, 1977. Case 2: A 43-year-old male who had had vasectomy 10 years ago underwent vasovasostomy on February 5th 1980. Sperm granuloma was observed at the time of operation. He fathered a baby on February 25th 1981. The important factors that determine the success of vasectomy reversal are the method and time of reversal. 1) Microsurgical two-layer vasovasostomy is the most reliable method among the various operations for vasectomy reversal. 2) A shorter duration between vasectomy and it's reversal, and the existence of sperm granuloma after previous vasectomy increase the possibility to restore fertility.
1977年，西尔伯和欧文报告了使用无夹板显微外科技术进行输精管复通术的出色结果。在此，我们报告两例因先前自愿输精管结扎导致男性不育的病例，通过显微外科输精管吻合术恢复了生育能力。这些病例中进行输精管复通术的原因是随后再婚。病例1：一名36岁男性，3年前接受了输精管结扎术，于1976年9月20日接受了输精管吻合术。术中未发现精子肉芽肿，但在输精管近端断端的液体中观察到了精子。他于1977年10月2日育有一婴。病例2：一名43岁男性，10年前接受了输精管结扎术，于1980年2月5日接受了输精管吻合术。术中观察到精子肉芽肿。他于1981年2月25日育有一婴。决定输精管复通术成功的重要因素是复通的方法和时间。1）显微外科双层输精管吻合术是各种输精管复通手术中最可靠的方法。2）输精管结扎术与复通术之间的时间间隔较短，以及先前输精管结扎术后存在精子肉芽肿，会增加恢复生育能力的可能性。
