Preliminary experience with a vacuum constriction device (VCD) as a treatment for impotence.


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.
