Over the past 25 years the association of varicocele with male subfertility has been repeatedly demonstrated and the beneficial effect of varicocele ligation in infertile men with oligoasthenospermia has been documented. Since the precise mechanisms by which a varicocele affects spermatogenesis are still unclear, the proper approach to the management of "asymptomatic" varicoceles is controversial.
在过去25年里，精索静脉曲张与男性生育力低下之间的关联已得到反复证实，精索静脉曲张结扎术对少弱精子症不育男性的有益效果也已得到记录。由于精索静脉曲张影响精子发生的确切机制仍不清楚，因此对“无症状”精索静脉曲张的恰当处理方法存在争议。
