Vacuum Constriction and External Erection Devices in Erectile Dysfunction

The development of external erection devices has evolved as the social stigma surrounding the treatment of erectile dysfunction has gradually disappeared during the late twentieth century. Although the success of surgical and medical therapy for erectile dysfunction has been documented, especially since the introduction of sildenafil citrate, patient demand for an effective, noninvasive, drug-free management of erectile dysfunction has remained.

This article examines the development, mechanism of action, efficacy, and patient satisfaction with regard to vacuum constriction and external erection devices.
