Male partners with left-sided varicoceles of 96 infertile couples were studied. Fifty-one patients were submitted to ligation of the testicular veins and 45 individuals were randomised as controls. During an observation period of 53 months (range 36 to 74 months) we found no statiscally significant improvement in the semen crude variables, the morphology or the progressive motility in the series of men submitted to surgery. The pregnancy rate was lower in those who had an excision of varicocelle.
对96对不育夫妇中患有左侧精索静脉曲张的男性伴侣进行了研究。51例患者接受了睾丸静脉结扎术，45例被随机作为对照。在53个月（范围36至74个月）的观察期内，我们发现接受手术的男性系列中，精液的原始变量、形态或进行性活力均无统计学上的显著改善。精索静脉曲张切除术患者的妊娠率较低。
