In contrast to the results with rigid-ended prosthetic devices implanted in the vas deferens of the dog, effective sperm transport was obtained for prolonged periods of time with flexible-ended (all soft) devices. Such transport could be halted by device occlusion with clips or shuttle stem valves. Opening the devices resulted once again in the passage of spermatozoa, indicating that these devices may be potentially useful as reversible male contraceptives. More research is necessary to determine the cause of an overall decrease in sperm output after device implantations and to evaluate any adverse side effects of such devices. Dacron velour-covered suture rings on the devices permitted effective tissue ingrowth and prevented leakage or recanalization.
与植入狗输精管的刚性末端假体装置的结果相反，柔性末端（全软质）装置能在较长时间内实现有效的精子运输。这种运输可通过用夹子或穿梭杆瓣膜阻塞装置来停止。打开装置后精子又会再次通过，这表明这些装置可能有作为可逆男性避孕药具的潜在用途。需要进行更多研究以确定装置植入后精子输出总体下降的原因，并评估此类装置的任何不良副作用。装置上覆盖涤纶丝绒的缝合环可实现有效的组织向内生长，并防止渗漏或再通。
