The semen from 20 men with varicocele was studied before and after surgical correction of the varicocele. The effect on sperm quality was only marginal and could not explain the fairly high conception rate (20%) after operation. The recommendation that varicocele in men with long-term infertility should be eliminated by ligation of the internal spermatic veins is still justified despite the absence of positive effects on sperm quality.
对20名患有精索静脉曲张的男性的精液在精索静脉曲张手术矫正前后进行了研究。手术对精子质量的影响甚微，无法解释术后相当高的受孕率（20%）。尽管对精子质量没有积极影响，但对于长期不育男性的精索静脉曲张应通过结扎精索内静脉来消除这一建议仍然合理。
