In this study the author examines the relationship between agenesis or atrophy of the testis and of the vas deferens. From a prospective study of 237 cases of unilateral and bilateral undescended testis, 12 cases of agenesis of a testis were seen; 9 of the 12 cases were associated with agenesis of the vas deferens and in 3 of these unilateral renal agenesis was also present, not necessarily ipsilaterally. Three other cases of testicular agenesis and four cases of extreme testicular atrophy were seen. In all seven, the vas deferens was present in part or in its entirety and roentgenography disclosed a normal upper urinary tract. Agenesis of the vas deferens was seen only in patients with monorchism. No patient was anorchid. It is concluded that an important link exists between agenesis of the vas deferens and agenesis of the testis.
在本研究中，作者研究了睾丸及输精管发育不全或萎缩之间的关系。通过对237例单侧和双侧隐睾症的前瞻性研究，发现12例睾丸发育不全；其中9例与输精管发育不全相关，且这9例中有3例还存在单侧肾发育不全，不一定是同侧。另外还发现3例睾丸发育不全及4例睾丸极度萎缩。在这7例中，输精管部分或全部存在，X线检查显示上尿路正常。输精管发育不全仅见于单睾症患者。无无睾症患者。结论是输精管发育不全与睾丸发育不全之间存在重要联系。
