How to Perform
Jelqing: Why It Doesn’t Work and Why It’s Dangerous
The Claims
Jelqing is promoted as a ‘natural’ way to increase penis size through manual stretching.
The Reality
No evidence it works: No peer-reviewed studies demonstrate permanent size increases.
Documented harms: Peyronie’s disease, nerve damage, vascular injury, erectile dysfunction.
What To Do Instead
If concerned about penis size, consult a urologist. Most men worried about size are actually within normal range.
Evidence Summary
Jelqing and similar 'penis enlargement exercises' have no scientific evidence supporting effectiveness and carry documented risks of injury. No peer-reviewed studies demonstrate permanent size increases. Case reports document injuries including Peyronie's disease, nerve damage, and erectile dysfunction.
