Among the many established and perhaps most credible benefits of using penis extenders is the way you can predict the possible gains.
Lengthening the penile tissue through traction has long been an established scientific fact.
Medical testing has likewise proven that using penis extender devices can result in growth, although achieving the desired results will depend on the user’s willingness to wear the device for the required number of hours.
Simply put, the use of penis extenders offers benefits that have been well-researched and documented in various published studies and clinical journals.
Here are some of them:

Italian Study

The study was published on May 10, 2010, in Britain’s Journal of Urology.
It offers one of the most established, proven, and authentic evidence of the effectiveness of using penis extenders.
It was performed by researchers from the University of Turin’s San Giovanni Battista Hospital.
Study participants were 16 highly-motivated male patients having an average age of 47 years.
During the 12-month study, the participants were made to wear a penis extender device anywhere from 4 to 6 hours each day for 6 months.
The average limp penis length of the men was measured at 2.8”, and when stretched, the average length was pegged at 3.8”.
In months 1, 6, and 12, follow-ups were made. The results at the conclusion of the study were terrific, to say the least. After 12 months, the following was discovered:
- The average limp penis length of a mere 2.8” increased by a remarkable 32% to 3.72”.
- The average stretched penis length increased by 18% from 3.8” to 4.45”.
The study concluded that wearing a penis extender device daily for 6 months would result to an increase in your penis length by as much as 32%, and will improve your erectile function by as much as 36%.
The study also reported high levels of satisfaction in all the categories.
According to the researchers, using penis extenders should be considered as an effective and minimally invasive treatment option for enlarging the penile shafts in men who are seeking solutions to their problem of having a small penis.
The study proves that penis extenders produce a durable and effective penis length gain – both in its limp and stretched states.
Canadian Study
Conducted by Canada’s Journal of Phalloplasty, the encouraging study showed that participants who utilized traction-based male enhancement devices enjoyed gains that ranged anywhere from 32% to 36%.
One of the most distinguishing features of the study was that although around 32% gain in penis length was reported for both limp and erect states, there was also a reported 36% increase in penis girth (thickness or width).
This makes the study results even more impressive.

More LessDuring the study, the participants were made to wear the penis extender device for around 6 – 8 hours each day for a total of 5 months.
Whatever gains were achieved during the study period remained even after the use of the device was stopped.
The use of the device also improved overall erectile strength. The study participants manifested an increase in erectile strength of an average of 36%, which was measured through penis hardness and blood circulation.
Scandinavian Study
The study conducted in Copenhagen’s Scandinavian Plastic Surgery Clinic was intended to assess the effectiveness of penis stretching through the use of professional penis extender devices.
It was presented on April 6-8, 1998 in Barcelona, Spain at the Genitourinary Reconstructive Surgery part of the 1st International Interdisciplinary Symposium.
The results showed impressive gains for all the participants.
The study involved 18 patients with ages ranging from 23 to 47 years who were made to wear the device for 12 hours every day for 8 – 24 weeks.
When the study was concluded, the subjects showed an increase in penis length of about 2” after over 4 months.
Researchers also discovered that the men had an average weekly increase in penis length of about 1.9 mm.
Other Studies Conducted
Among the other studies conducted was a Journal of Sexual Medicine research published work in 2008.
The results of the study showed that using penile extenders can help decrease penile curvature, and can help make the penis a little longer.
In today’s age of evidence-based medicine, the various clinical and scientific studies discussed above help prove that traction devices or penis extenders can be utilized effectively as a viable option to the invasive and often expensive penis augmentation or surgery.
Penis extenders offer the same desired results at a more affordable price and with less risk.
