What this trial studies

This clinical trial aims to evaluate the safety and feasibility of a non-invasive, 3D-printed external penile device designed to help men with erectile dysfunction achieve satisfactory sexual intercourse. Participants will include men over 18 years old experiencing moderate to severe erectile dysfunction due to various causes. The study will assess how effectively the device can assist in restoring sexual function and satisfaction. The trial will take place at Stanford Health Care, where participants will be monitored for their experiences and outcomes while using the device.

Why it matters

Potential benefit: If successful, this device could provide a new, non-invasive treatment option for men suffering from erectile dysfunction.

How similar studies have gone: While there have been various approaches to treating erectile dysfunction, the use of a 3D-printed external device is a novel approach that has not been extensively tested in clinical settings.
