Our results indicate that the physical presence of a varicicele is not always associated with an alteration in sperm cell concentration and that a reduction of semen characteristics is more likely in men with reduced sperm counts. Our study also indicates that a higher pregnancy rate after varicocele ligation occurred in wives of patients in the lower sperm count groups. Other forms of therapy also were found to be associated with pregnancy in wives of men with varicoceles. The post-surgical pregnancy rate was 25 per cent compared to 12 per cent in the non-surgical group.
我们的研究结果表明，精索静脉曲张的实际存在并不总是与精子细胞浓度的改变相关，而且精液特征的降低在精子计数减少的男性中更为常见。我们的研究还表明，精子计数较低组患者的妻子在精索静脉曲张结扎术后妊娠率较高。其他治疗方式也被发现与精索静脉曲张男性患者妻子的妊娠有关。手术组的术后妊娠率为25%，而非手术组为12%。
