The evidence in words
The verdict
For erectile function (humans), Horny Goat Weed earns evidence grade D (unclear effect, low consistency) — the evidence does not support the claim. No real trials
How it might work
Icariin weakly inhibits PDE5 (the target of erectile-dysfunction drugs) in lab studies.
How to use it
Not recommended given the lack of human data.
Safety & cautions
Limited data; possible cardiovascular effects at high doses.
Bottom line
A plausible mechanism with no real human evidence and typically sub-therapeutic dosing. Skip it for proven options.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
