Varicoceles have been shown to be detrimental to spermatogenesis and to cause male infertility. Patients with infertility referred for spermatic vein Doppler ultrasound evaluation were studied prospectively to correlate the findings on physical examination and those on Doppler ultrasound evaluation. Twelve out of thirty-four spermatic veins (35%) with no evidence of varicocele on physical examination were found to have definite reflux on Doppler ultrasound examination, while all the unoperated spermatic veins with clinically evident varicoceles had reflux on Doppler ultrasound examination. In the absence of newer methods of diagnosis like high resolution real-time scrotal ultrasonography or scrotal colour Doppler duplex ultrasonography, our results support the use of Doppler ultrasound to detect subclinical varicoceles in patients with infertility but we do not recommend its use in patients with clinically evident varicoceles.
精索静脉曲张已被证明对精子发生有害并可导致男性不育。对因不育前来接受精索静脉多普勒超声评估的患者进行了前瞻性研究，以关联体格检查结果和多普勒超声评估结果。在体格检查中无精索静脉曲张证据的34条精索静脉中，有12条（35%）在多普勒超声检查中发现有明确的反流，而所有临床上明显有精索静脉曲张且未手术的精索静脉在多普勒超声检查中均有反流。在缺乏高分辨率实时阴囊超声或阴囊彩色多普勒双功超声等更新诊断方法的情况下，我们的结果支持使用多普勒超声来检测不育患者的亚临床精索静脉曲张，但我们不建议在临床上明显有精索静脉曲张的患者中使用。
