Histometric studies in 34 boys with retractile testes and 21 controls with normal descent showed no significant statistic differences with regard to tubulus diameter and spermatogonia count. Operative treatment of retractile testes, therefore, is not indicated.
对34名患有回缩性睾丸的男孩和21名睾丸下降正常的对照组进行的组织测量学研究显示，在小管直径和精原细胞计数方面没有显著的统计学差异。因此，不建议对回缩性睾丸进行手术治疗。
