Do you have a curved penis?

Peyronie's disease is a tissue disorder, which affects between 1-4% of all men. In some cases, it can lead to severe curvature in the penis - something that can cause discomfort, affect sexual performance and lower self-esteem.

For 14 years, the Jes-Extender has been recognised as a medically proven solution to Peyronie's disease. Clinical tests, performed by independent doctors, have in fact shown the device to be incredibly effective in straightening the penis. While there are a number of techniques on the market to correct Peyronie's disease, using the Jes-Extender is the only one that will straighten your penis and increase your size at the same time.

Peyronie's disease - the background

Peyronie's disease has no known cause, but it is characterized by a plaque or hard knot which is formed in the penis. Peyronie's disease is often quite mild, but it can also be severe. At times, symptoms can develop incredibly quickly - but some men develop a curvature over a number of years. The sexual problems that arise due to this condition, can, in some cases, cause a couple's physical and emotional relationship to break down and greatly damage the man's confidence. However, a smaller number of patients with mild Peyronie's disease see the inflammation disappear by itself, without ever experiencing the severe pain or anxiety that affects some.

How does the Jes-Extender correct Peyronie's disease?

When you wear the Jes-Extender penis enlargement product, your penis is subjected to constant physical traction. This traction leads to an increase in both the length and girth of your penis - but it also has the effect of straightening out the curve. Inevitably, in fact, the curved part of the penis is subjected to the greatest influence from the traction - and the natural consequence of giving you the straightness you crave.

Clinical trials

As well as being a proven penis enlargement product, the Jes-Extender has been proven to be a more successful treatment of Peyronie's disease than many surgical alternatives. The following test results refer to a clinical trial carried out by Doctor J. Ruiz-Romero and Doctor J. Ponce de León Roca, of Barcelona, Spain:

Penile Measurement

Penile Measurement




Before treatment
Painful stage = 2
Painless stage = 6
After treatment
The 2 patients that were under painful stage of Peyronie' Disease, referred penile pain resolution after 2 - 3 months of treatment.

Penile Length:

Before treatment
Subjective Penile Shortening = 8
Shortening sensation varied from 2 cm. to 5 cm.
After treatment
Initial length Recuperation = 1
Lengthening of > 2 cm. = 4
Lengthening of < 2 cm. = 3
Without modification = 0
Shortening = 0

Peyronie's disease treatment

All patients were treated with continuous traction using The Jes-Extender®, adjusting it with a force of traction between 1.200g. and 1.500g.

The amount of time (total of daily hours of use) varied:
5 patients used it between 6 and 9 hours a day.
3 patients used it between 9 and 12 hours a day.


Average = 16,8 weeks (Range:8-24 weeks)
Force of traction = 1.200 - 1.500 g.
Use of The Jes-Extender® :
< 6 hours/day = 0
6 - 9 hours/day = 5
9 - 12 hours/day = 3


Continuous traction with The Jes-Extender® seems to be an adequate therapeutic option to treat Peyronie's disease, because it leads to:

  • A decrease in penile incurvation
  • A decrease in the size and consistency of fibrous plaques
  • The recovery of penile length

It is logical to think that traction force supplied by The Jes-Extender® compensates and minimizes fibrous plaque retraction force.

As you can see from the results above, a curved penis can be corrected using the Jes-Extender® penis enlargement device.
If you still have any doubts please ask and we will forward medical information to your doctor.
