1937年,wilhem等发现精索静脉曲张(varico■le,VC)可影响精子发生。但直到1952年,Tulloch报告了一例VC无精子病人在进行双侧精索静脉结扎术后,精子计数改善、生育能力恢复之后,才引起研究者们的广泛重视。Greenberg汇总了几次大规模的临床调查资料,得出一般人群的VC发病率为15％(8～18％),而在不育男子中的发病率为37％(23～39％)。大量的资料表明, In 1937, wilhem et al found varicocele (varico ■ le, VC) can affect spermatogenesis. However, it was not until 1952 when Tulloch reported that a case of VC azoospermia developed bilateral spermatic vein ligation and improved sperm count and reproductive fertility before attracting the attention of researchers. Greenberg summarizes several large-scale clinical survey data and found that the incidence of VC in the general population is 15% (8-18%) and in infertile men it is 37% (23-39%). A lot of information shows that,
