First seen Jun 27, 2026 · Last updated Jul 30, 2026 · Updated 2 times
Summary
This study tests whether stimulating the pudendal nerve with a small electrical current can improve erections in men with erectile dysfunction. 72 men aged 18-60 will receive either real stimulation or a sham procedure. Researchers will measure changes in erectile function, hardness, and quality of life over three months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- percutaneous electrical nerve stimulation
- What this could lead to
- If it works, this could offer a non-drug, non-surgical option for men with erectile dysfunction.
- What could go wrong
- This is a small, early-stage trial with no blinding, and results may not apply to all causes of ED. The placebo group also receives a needle procedure, so any benefit may be partly due to a placebo effect.
