In 35 men with organic impotence we have tested a noninvasive device which uses a vacuum to produce an erection-like state and rubber bands to maintain this state. The subjects were first evaluated to determine the cause of their impotence and to establish that it had an organic basis. Using this device 32 of the 35 subjects achieved penile rigidity sufficient for vaginal penetration. Subjects were studied with the rubber bands constricting the base of the penis for thirty minutes. During that period, blood flow continued, but at a less than normal rate. Of 30 men followed up from eight to twenty-two months, 24 use the device regularly and report that they are satisfied. Four subjects have not yet tried to use it, and 1 no longer needs it. One man was dissatisfied because the rigidity begins to decrease after five to ten minutes of sexual activity, even though it did not change over a thirty-minute period when originally tested in the laboratory. Ecchymoses of the penis, probably due to excess vacuum, developed in 3 subjects. In 8 other men petechiae of the skin of the penis developed on one or more occasions. These ecchymoses and petechiae were painless and disappeared without treatment. No other complications occurred. The vacuum device appears to be a safe and inexpensive way for an impotent man to make the penis rigid enough to engage in sexual intercourse.
我们对35名患有器质性阳痿的男性进行了测试，使用一种非侵入性装置，该装置利用真空产生类似勃起的状态，并使用橡皮筋维持这种状态。首先对受试者进行评估，以确定其阳痿的原因，并确定其具有器质性基础。使用该装置，35名受试者中有32名实现了足以进行阴道插入的阴茎硬度。对受试者进行研究时，用橡皮筋束紧阴茎基部30分钟。在此期间，血流持续，但速率低于正常水平。在随访8至22个月的30名男性中，24名经常使用该装置并报告他们感到满意。4名受试者尚未尝试使用，1名不再需要使用。有一名男性不满意，因为即使在实验室最初测试时在30分钟内阴茎硬度没有变化，但在性活动5至10分钟后硬度开始下降。3名受试者出现了可能由于过度真空导致的阴茎瘀斑。另外8名男性在一个或多个场合出现了阴茎皮肤瘀点。这些瘀斑和瘀点无痛，未经治疗就消失了。没有发生其他并发症。对于阳痿男性来说，真空装置似乎是一种安全且廉价的使阴茎硬度足以进行性交的方法。
