Bilateral testicular biopsies were performed on 66 children undergoing orchiopexy for unilateral cryptorchidism and the tubular fertility index (TFI) recorded. The results in both the descended and undescended testes at various ages were compared with previously reported control data. There were no significant differences between the germ cell activity of the scrotal testis in cases with unilateral cryptorchidism and that of controls. By contrast, the mean TFI of the undescended testis was significantly less than that of control patients of all ages. In neither group was there evidence of a progressive loss of germ cell activity during childhood. It is concluded that there is little to be gained from very early orchiopexy, performed before the third year of life.
对66例因单侧隐睾症接受睾丸固定术的儿童进行了双侧睾丸活检，并记录了小管生育指数（TFI）。将不同年龄的已降入阴囊和未降入阴囊的睾丸的结果与先前报道的对照数据进行了比较。单侧隐睾症患者阴囊内睾丸的生殖细胞活性与对照组之间无显著差异。相比之下，未降入阴囊的睾丸的平均TFI显著低于各年龄段的对照患者。两组均未发现儿童期生殖细胞活性有逐渐丧失的迹象。得出的结论是，在生命的第三年之前进行极早期睾丸固定术几乎没有益处。
