Summary

This phase 3 trial is testing whether Testofen, a standardized fenugreek extract, can improve erectile function in healthy men aged 40 to 75 with mild to moderate erectile dysfunction. Participants take either 300 mg or 600 mg of Testofen or a placebo daily for 12 weeks. The study measures changes in erectile function, erection hardness, and overall sexual satisfaction using standard questionnaires.

What this could mean

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

Active substance
a fenugreek extract called Testofen
What this could lead to
If it works, this could offer a natural supplement option for men seeking to improve erectile function without prescription drugs.
What could go wrong
This is a relatively small trial, and the effect may be modest or no better than placebo. Dietary supplements are not as strictly regulated as medications, so results may vary.
