The VCD is a mechanical device that produces an erection by creating a vacuum of up to 250 mm Hg. Up to now, it has been used in patients with organic impotence (mainly diabetic) with a high level of success and minimal side effects. This study reports preliminary findings on the application of the VCD in both organic (e.g. diabetics) and psychogenic cases of impotence. All subjects were able to develop an adequate erection with the instrument making intercourse possible. However, the frequency of use dropped sharply as the study progressed and some subjects and their sexual partners expressed reservations about continuing with it. Mild numbness in the penis was experienced by several users.
真空收缩装置（VCD）是一种通过产生高达250毫米汞柱的真空来实现勃起的机械设备。到目前为止，它已被用于治疗器质性阳痿患者（主要是糖尿病患者），成功率很高且副作用极小。本研究报告了VCD在器质性（如糖尿病患者）和心因性阳痿病例中的应用初步结果。所有受试者使用该器械都能实现足够的勃起，从而可以进行性交。然而，随着研究的推进，使用频率急剧下降，一些受试者及其性伴侣对继续使用表示保留意见。有几位使用者感到阴茎轻度麻木。
