There have been many products with claims of penis enlargement. They can be male enhancement pills, pumps, massage techniques like jelqing or milking or the use of a penis extender. While penis enlargement is possible the claims made by too many products are untested and the results are unreliable. However, tissue stretching and growth from traction is a biological fact and has been proven by medical practices. From the straightening of joints to the lengthening of muscles and nerves which have been damaged because of trauma or surgery by use of traction has been practiced for decades.

Recently the medical practice of traction has been applied to the penis because of injury, surgery or diseases related to the penis. The results of several clinical trials and medical studies have indicated that using a penis extender will not only straighten a bent or curved penis but also increase its overall all size and length. A review of those studies follows.

University of Turin, Italy.

In March of 2009, a study on the effectiveness of using a penis extender was published in the British Journal of Urology. This study was done by researchers from San Giovanni Battista Hospital at the University of Turin, Italy.

The 12-month study included 16 participants who had an averaged age of 47 years. The men were required to wear the penis extender device for 6 to 8 hours per day over a 6 month period. Both the flaccid and stretched lengths of the men’s penises were recorded. The average flaccid length was 7.15 centimeters or 2.82 inches and the average stretched length was 9.62 centimeters or 3.79 inches.

There were measurements taken after the first, third, sixth months during the study and a follow-up six months after the men had concluded wearing the penile extender. At the conclusion of the 12-month study, the average flaccid penis length was 9.45 centimeter or 3.72 inches. An increase of thirty-two percent. The average stretched penile length was 11.32 centimeter or 4.45 inches. An increase of eighteen percent. Men who wore the penis extender daily during the study increased their erections by up to thirty-six percent. The participants rated the results as highly satisfied.

The researchers concluded, “Penile extenders should be regarded as a minimally invasive and effective treatment option to elongate the penile shaft in patients seeking treatment for a short penis.”

Scandinavian Clinic of Plastic Surgery

In April of 1998 at the First International Interdisciplinary Symposium on Genitourinary Reconstructive Surgery held in Barcelona, Spain, the Scandinavian Clinic of Plastic Surgery, Copenhagen presented their study evaluating using a professional penis extender device for a penile extension.

18 men elected to take part in the study. They ranged in ages from twenty-three to forty-seven years old. The participants were required to wear the penile extender for daily for 12 hours per day for up to 24 weeks.

The study concluded that the men showed an average increase in penis length over the four-month period. The weekly increase averaged 1.9 millimeters and the total penis enlargement averaged two inches. Learn more at

Canadian Journal of Phalloplasty

The Canadian Journal of Phalloplasty carried out a study which showed some amazing results where penis enlargement was concerned. In their study, they found that men you used a penis extender or male traction device had a 32 percent increase in penis length. The men also had a 36 percent increase in penis thickness or girth.

The participants were instructed to wear the penile extender over five months for six to eight hours per day. The men showed that blood circulation in the penis and subsequent hardness (erectile strength) had increased an average of thirty-six percent. Remarkably the gains in penis thickness, length and hardness were maintained even after the men stopped using the penis extender.

Journal of Sexual Medicine.

In 2008 the Journal of Sexual Medicine conducted a study on the usage of a penis extender device to treat curved penises. They found that there was also some lengthening of the penis included with the straightening of the penis. Learn more at

The scientific and medical indications are that using a penis extender will, in fact, increase the overall length of the penis as well as increasing the thickness as well. It is a viable alternative to penis surgery with fewer possible negative side effects.
