Testicular development was studied in prepubertal boys with retractile testes. Testicular volume, the diameter of the seminiferous tubules and the number of spermatogonia in the tubules were decreased in cases of unilateral retractile testis, when compared with values for the contralateral normally descended testis. On the other hand, in patients with a unilateral retractile testis and contralateral inguinal testis, there was no difference in the developmental parameters between the two testes. These results suggest that the retractile testis has developmental failures characteristic of a cryptorchid testis and therefore requires orchiopexy.
对青春期前回缩性睾丸男孩的睾丸发育情况进行了研究。与对侧正常下降的睾丸相比，单侧回缩性睾丸病例的睾丸体积、曲细精管直径和管内精原细胞数量均减少。另一方面，在单侧回缩性睾丸和对侧腹股沟睾丸患者中，两个睾丸的发育参数没有差异。这些结果表明，回缩性睾丸具有隐睾的发育异常特征，因此需要进行睾丸固定术。
