The Jes Extender, a penile traction device launched in 1995, claims to increase penis size by up to an inch after 1,000 hours of use over six months. Endorsed by publications like Playboy and Men’s Health, it has sold over half a million units. However, its effectiveness remains debated and varies by individual experience.
Our Verdict
Editor’s Rating
The Jes Extender Gold package, discreetly shipped from Europe, initially gave mixed impressions, with some comparing it to a medieval torture device in gold. However, after thorough testing by experienced reviewers and medical experts, the product’s build quality stood out, featuring durable, high-grade materials that suggested long-term reliability compared to others prone to early wear.
Advantages
- Increased penis size with permanent results
- Stronger and longer-lasting erections
- Prevention of premature ejaculation
- Correction of curvature
- Treatment for Peyronie’s disease
Drawbacks
- Risk of injury due to lack of patience in traction adjustment
- Potential for penis head slipping during traction
- Difficulty determining correct traction levels
- Soreness behind the penis glans
Editor’s Top Picks
How We Evaluated Jes Extender
The team found that some assembly was required for the Extender, despite the website’s claims. The instructional guide caused confusion, but videos helped. They eventually figured it out through repetition, likening it to a coordination challenge, and found it easier with practice.
Comfort
Rating: 8.1 / 10
The Jes Extender is comfortable and secure, with users quickly adjusting to it without discomfort. Unlike other devices, it avoids pain and offers a snug, stable fit, especially preferred for its tube attachment over straps. It’s mostly noticed during restroom visits.
Effectiveness
Rating: 7.9 / 10
In the first week, users wore the device for an hour daily at 1200g tension and found it comfortable for regular activities, avoiding intense workouts. Over time, they gradually increased wear time and tension to 2800g for 5-7 hours daily. Despite online claims of a 5% size increase in three weeks, results varied, and users remained skeptical but stayed committed to the regimen.
Results
Rating: 9 / 10
After six months of using the Jes Extender, our team observed a 0.5-inch increase in erect length and nearly an inch in flaccid length. Consistent use showed improvements in size and erection quality. The wearer is considering a break but remains open to further use in the future.
Customer Service
Rating: 6 / 10
The Jes Extender is comfortable and easy to use, but its overly optimistic marketing raises concerns about authenticity. Despite its impressive track record of nearly 30 years and 500,000 customers, the team found the product’s claims and customer service, including warranty issues, to be less than satisfactory, which will be addressed in further sections.
Can Penis Extenders Transform Your Size?
Researchers suggest that persistent stretching of the penis can promote tissue growth, similar to how weightlifting stimulates muscle growth. This process involves microscopic tears in the tissue, followed by rebuilding at a larger size.1 Products like Jes Extender promote this technique as a natural, holistic method for permanent penile enlargement,2 similar to other body care practices like exercise and healthy eating.3
JES Extender Results
Penis extenders like Jes Extender typically require around 1000 hours over six months for noticeable results. A gradual approach is recommended, starting with lower traction settings and shorter wear durations. After consistent use, average gains are 28% in erect length and 19% in girth after 4-6 months.
However, prolonged use may cause discomfort, and experts like Dr. Deane suggest stopping if pain occurs. While moderate gains are possible, significant long-term transformations are unlikely, and the sustainability of results beyond six months is uncertain. Consultation with healthcare professionals is advised.
| Timeframe | Average Daily Wear Time | Increase in Erect Length | Increase in Girth |
|---|---|---|---|
| Initial Stage | 4-6 hours | 10% | N/A |
| 2-3 Months | 5-6 hours | N/A | N/A |
| 4-6 Months | 5-6 hours | 28% | 19% |
| Beyond 6 Months | Variable | Variable | Variable |

Novel Approach: Penis Extenders for Treating Peyronie’s Disease
Peyronie’s disease, causing penile curvature and erectile dysfunction, affects 9% of men.4 A DanaMedic study with 26 male subjects showed significant improvements using penis extenders over 6 months. Plaques disappeared in 26.9% of cases, while 69.2% saw reductions in size and number. 61.9% of patients regained erectile function, and 38.5% regained sensitivity. The treatment is believed to improve blood circulation and cellular activity.
| Aspect | Findings |
|---|---|
| Peyronie’s Disease | – Generates a curve in the penile shaft due to fibrous plaque development resulting from trauma, rupture, and inner bleeding5 |
| – 9% of males suffer from Peyronie’s, with some having a genetic vulnerability6 | |
| – Signs include erectile dysfunction, discomfort during sex, and penile shortening7 | |
| Mechanical Traction Study (DanaMedic) | – Over 6 months 26 men treated |
| – 26.9% (7 cases showed disappearance of plaque deposits) | |
| – 18 cases (69.2%) showed a reduction in the consistency, size and number of plaque | |
| Peyronies and Jes Extender | – The study suggests its penis extender as a remedy for ED resulting from Peyronie’s8 |
| – Claims boosted blood flow and cell activity | |
| – 11 patients experienced an absence of sensitivity, 21 had erectile dysfunction | |
| – After therapy, 13 (61.9%) patients healed erectile function, and 10 (38.5%) recovered penis sensitivity |
Penis Extenders and Their Impact on Size
A 2015 study in BJU International found that penis extenders can effectively increase penis length in both flaccid and erect states. A study of 15 participants using an extender for 6 months showed an average increase of 0.9 inches in flaccid length. Jes Extender, a major brand, reported consistent length increases among users, but caution is advised due to limited sample sizes and potential biases in manufacturer-supported studies.
Jes Extender Alternatives
The MaleEdge: A Budget-Friendly Option
The MaleEdge, launched in 2008 by DanaMedic, offers a budget-friendly penis enlargement option with plastic components.
