If you want to see measurable changes, follow these evidence-informed principles.
Let’s be blunt: There are zero high-quality clinical trials on jelqing. The medical community largely dismisses it as dangerous folklore.
However, two relevant studies exist:
Urologists consistently state that any permanent increase in penile size beyond natural variability is extremely difficult. Most "before and after" results are due to:
Gains happen during healing, not during jelqing. Schedule: jelqing before after results
Let’s examine three anonymized, verified jelqing logs from PE forums (identifiers removed).
Here’s the uncomfortable truth: No peer-reviewed, large-scale study has validated jelqing for permanent enlargement.
What we have instead:
A 2019 review in Sexual Medicine Reviews concluded: “Manual stretching techniques lack rigorous evidence but persist due to low cost and perceived low risk compared to surgery.” If you want to see measurable changes, follow
What we can say with confidence: Jelqing reliably improves erection quality, flaccid fullness, and vascular health. Permanent gains beyond 1” length or 0.5” girth are exceptional, not typical.
After one year, gains slow dramatically. Additional length beyond 1 inch is rare from jelqing alone. Most advanced users incorporate devices (extenders, pumps, clamping) to continue progress.
Long-term before/after (12-18 months):
Flaccid changes are often more dramatic – many report a 1-2 inch increase in flaccid length, which significantly impacts confidence in locker rooms or intimate settings. Urologists consistently state that any permanent increase in
Not all jelqing before and after photos show growth. Some document injury.
Warning signs to stop immediately:
Case example of bad before/after:
User “N” posted a 2-month before/after showing a 0.4” girth gain. The after photo also revealed a dark, swollen ring at the base and a slightly bent erection. He later admitted to ignoring pain and continuing jelqing. His final update: a urologist diagnosed lymphangiosclerosis.
