Daily vacuum device therapy for penile numbness and sensation changes
Official title: Vacuum Therapy for the Treatment of Penile Numbness/Sensory Changes
Run by Ottawa Hospital Research Institute · NCT07171567 · Data updated 2026-11-12
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.

Is this trial a fit for you?
✓Likely a 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.
✕Probably 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.

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.
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 gone: 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.
