NCT04720755

Brief Summary

Low-intensity extracorporeal shock wave therapy (Li-ESWT) has shown promise as a novel treatment for erectile dysfunction (ED), though the the mechanism of action and optimal protocol for administration has not been well-established. The aim of this study is to assess for subjective and objective improvements in erectile function following treatment with Li-ESWT.

Study Arms (1)

Treatment

EXPERIMENTAL

Participants will receive twice-weekly Li-ESWT treatments of 0.2mJ/mm² over 3 treatment sites along the dorsal penile shaft (distal, mid-shaft, proximal), 1500 shocks per treatment (500 shocks per treatment site) for a total of 3000 shocks per week, for 6 weeks (total of 18,000 shocks)

Device: Low-Intensity Extracorporeal Shock Wave Therapy

Interventions

Twice-weekly treatments for 6 weeks, of 0.2mL/mm\^2 administered for 500 shocks per treatment site, for a total of 3000 shocks per week.
