This will try daily use of a Health Canada–approved vacuum erection device for six months in adult men with penile numbness to see if people can use it regularly and whether symptoms change.

What this trial studies

This is a prospective, uncontrolled, hypothesis-generating pilot enrolling eight adult men with penile numbness seen at the Ottawa Hospital Men's Health Clinic. Participants will use a Health Canada Class I vacuum erection device daily for six months with biweekly check-ins and monthly questionnaires delivered via LimeSurvey, including the IIEF-5 and two custom penile sensitivity instruments. The primary aim is to examine feasibility and acceptability using adherence and completion metrics; symptom changes will be explored with within-subject comparisons (e.g., Wilcoxon signed-rank test). Results are descriptive and intended to inform the design of larger, controlled studies.

Who should consider this trial

Good fit: Adult men (age 18 and over) who have been evaluated by a urologist for penile numbness/insensitivity and are willing to use a vacuum erection device daily for six months are ideal candidates.

Not a fit: Men under 18, those who have not been seen by a urologist for their symptoms, or individuals whose numbness is due to conditions unlikely to respond to mechanical stimulation may not receive benefit.

Why it matters

Potential benefit: If successful, this could offer a simple, non-invasive option to improve or manage penile sensation in affected men.

How similar studies have performed: Vacuum erection devices are established for erectile dysfunction but using daily VED therapy specifically to address penile numbness is largely novel with limited prior evidence.
