Of 170 patients having undergone orchiopexy for unilateral cryptorchid testes, 90 responded to our inquiry. Testicular size was measured in 55 patients using an accurate and practical orchiometer (punched-out orchiometer) developed in our department. In boys under ten years of age (prepubertal), testicular development was minimal, and the operated on and contralateral testes were not significantly different. With the onset of puberty, both testes enlarged, and no significant differences were observed. However, by age fourteen the side operated on was significantly (p less than 0.05) less well developed than the contralateral testis. No difference was detected clinically between the operated on and contralateral testes when the contralateral testis was less than 10 mL in volume. When the contralateral testis was greater than 15 mL, however, a significant difference was detected both statistically (p less than 0.05) and clinically. The findings suggest limited prospects for the development of testes that are operated on at puberty.
在170例因单侧隐睾接受睾丸固定术的患者中，90例回复了我们的询问。我们使用本部门研制的精确实用的睾丸测量器（冲孔式睾丸测量器）对55例患者的睾丸大小进行了测量。在10岁以下的男孩（青春期前）中，睾丸发育极少，手术侧和对侧睾丸无显著差异。随着青春期的开始，双侧睾丸均增大，未观察到显著差异。然而，到14岁时，手术侧睾丸的发育明显（p小于0.05）不如对侧睾丸。当对侧睾丸体积小于10 mL时，手术侧和对侧睾丸在临床上未检测到差异。然而，当对侧睾丸体积大于15 mL时，在统计学上（p小于0.05）和临床上均检测到显著差异。这些发现表明青春期接受手术的睾丸发育前景有限。
