Fifty-two infertile men with varicoceles were subjected to bilateral testicular biopsy to detect the effect of the varicocele on each testis. The results indicate that varicocele can result in infertility primarily through sloughing of immature cells or through arrest of spermatogenesis at the spermatid or primary spermatocyte stage. The effect is bilateral but is more marked on the varicocele side. However, the presence of a varicocele could not explain the infertility of seven men with normal biopsies and of four men with a normal biopsy on the varicocele side and arrest on the other side.
52名患有精索静脉曲张的不育男性接受了双侧睾丸活检，以检测精索静脉曲张对每个睾丸的影响。结果表明，精索静脉曲张主要通过未成熟细胞脱落或精子发生在精子细胞或初级精母细胞阶段停滞而导致不育。这种影响是双侧的，但在精索静脉曲张一侧更为明显。然而，精索静脉曲张的存在无法解释7名活检正常的男性以及4名精索静脉曲张一侧活检正常而另一侧停滞的男性的不育原因。
