One hundred men with proven fertility who presented for vasectomy consultation were examined for testicular size and presence of a varicocele, including examination with the Doppler stethoscope for the presence of subclinical varicocele. A diagnosis of varicocele was established in 61%. In 17 patients, the varicocele was evident clinically, whereas in 44 patients it was subclinical (8 bilateral). There was a discrepancy in testicular size in 22 patients, but this group included 8 men without varicoceles and 7 with subclinical varicoceles. It is apparent that varicoceles, especially subclinical varicoceles, are an extremely common finding, even in a group of fertile men. The results suggest that subclinical varicoceles have no role in male infertility.
对100名前来咨询输精管切除术的已证实具有生育能力的男性进行了睾丸大小和精索静脉曲张检查，包括使用多普勒听诊器检查是否存在亚临床精索静脉曲张。61%的患者被诊断为精索静脉曲张。17例患者临床上精索静脉曲张明显，而44例为亚临床型（8例双侧）。22例患者存在睾丸大小差异，但该组包括8例无精索静脉曲张的男性和7例亚临床精索静脉曲张患者。很明显，精索静脉曲张，尤其是亚临床精索静脉曲张，即使在一群有生育能力的男性中也是极为常见的发现。结果表明，亚临床精索静脉曲张与男性不育无关。
