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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
low-dose peripheral nerve stimulation
What this could lead to
If it works, this could offer a non-drug, non-surgical option to improve erections and quality of life for men with erectile dysfunction.
What could go wrong
This is a small, early registry study with only 24 participants and no control group. Results may not apply to all men, and benefits may be temporary.
