One hundred and eighty-seven male partners of involuntarily infertile couples were evaluated and found to have dilatation of the left spermatic vein. One hundred and forty-nine underwent varicocelectomy and achieved a statistically significantly improved conception rate as compared with the nonoperated group. Although 70.5% of men whose wives subsequently conceived had improved semen count and motility postoperatively, no parameter distinguished these men from other patients with similar improvement who remained infertile.
对187名不育夫妇的男性伴侣进行了评估，发现他们存在左侧精索静脉曲张。149名患者接受了精索静脉曲张切除术，与未手术组相比，其受孕率在统计学上有显著提高。尽管随后妻子受孕的男性中有70.5%术后精液数量和活力有所改善，但没有任何参数能够将这些男性与其他精液同样改善但仍未生育的患者区分开来。
