Shockwaves could help men with ED – but not everyone
NCT ID NCT07592533
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a device that delivers gentle shockwaves to the penis to help men with erectile dysfunction (ED). Researchers want to find out which patients see real improvement after treatment. About 157 men with ED will receive the therapy and be followed for 3 months. The goal is to better predict who should try this option and who might need other treatments.
