NCT ID NCT06397612
First seen Jun 27, 2026 · Last updated Jul 30, 2026 · Updated 2 times
Summary
This study tests whether low-dose electrical stimulation of the pudendal nerve can improve erectile function in men with mild to moderate erectile dysfunction. Twenty-four men will receive a 20-minute stimulation session, and researchers will measure changes in erection hardness, sexual function, and quality of life up to three months later. The goal is to see if this non-surgical approach offers a safe, effective treatment option.
