Penis Augmentation Studies

Claiming a method works without bringing scientific proof is easy, but contradicts protecting people which are going to undergo such treatments. For this reason, we have gathered a list of penis augmentation studies related to several penis enlargement solutions.

A Critical Analysis of Penile Enhancement Procedures for Patients with Normal Penile Size: Surgical Techniques, Success, and Complications

In this study (published in European Urology, April 2009) its authors (Vardi Y., et al.) have systematically reviewed articles about penis enhancement with penis surgery procedures, published in English language between 1965 and 2008. From the 176 papers found, they excluded articles where less than five cases were described and articles where the type of treatment or the outcome of it was not clear.

From the 34 articles that remained for analysis, they concluded penis enhancement surgery can provide 1-2 cm increase in penile length and a 2.5 cm increase in penile girth in average. In unwanted results and complications found, they highlight frequent occurrence of penile deformity, penile shortening, scarring, granuloma formation, migration of injected material and sexual dysfunction. They also notice low satisfaction rate with the results in patients.

Penile Enhancement Via Extender Study -Without Surgery- Using the Penis Extender Device

This one of the first comprehensive studies in the field of penis enlarger was done in 1998 and presented during the 1st Virtual Sexology and Hispano-American Sexual Education Congress in February 2001 by Dr. Eduardo A. Gomez de Diego.

In the study 37 healthy patients in Spain (age 22 – 60) were measured at the beginning and at the end of the treatment. The traction force used was 600 g during the 1st month, 900 g during the 2nd month, 1100 g during 3rd and 4th months and 1200 g during 5th and 6th months for 10 hours daily, every day for a period of 3-6 months. Results show an average of 0.5 cm growth in length per month in erected and flaccid state; and a growth of 0.6 – 1 cm in perimeter in erected and flaccid state during the treatment. The growth correlates with the time the device is used; the greater the time, the greater the growth. The amount of growth does not depend on the previous natural size of the penis. The results also state the age of the patient does not effect the growth.

Effects on Penile Size with Penile Extensor by Traction

Other studies have proven the results observed by Dr. Gomez de Diego. For example, this study which was conducted in 2005 in Shanghai Institute of Andrology, Shanghai, China by a team of Chinese doctors (Lee Z., Zhu XB., et al.) on 30 patients, aged 16 – 70. The penis extender device was worn for three months, 9 hours a day. After three months penis length has increased by 2.1 cm in flaccid and by 2.0 cm in erected state. The perimeter increased 1.8 cm in flaccid and 1.9 cm in erected state.

A Pilot Phase-II Prospective Study to Test the ‘Efficacy’ and Tolerability of a Penile-Extender Device in the Treatment of ‘Short Penis’

This is one of the latest and most important studies (published in the British Journal of Urology International, March 2009) conducted by Gontero P., et al. in Turin, Italy. 15 patients were subdued to the treatment of at least 4 hours daily for 6 months. The observed gains were 2.3 cm and 1.7 cm for the flaccid and erected penis respectively. The gained growth was measured again and confirmed 6 months after the end of the treatment. The study reports only mild improvement in girth, though.

Effect of Penile-Extender Device in Increasing Penile Size in Men with Shortened Penis: Preliminary Results

This study conducted in Tehran, Iran in 2008 on 23 individuals (mean age of 26.5 years) by Nikoobakht and his team (published in The Journal of Sexual Medicine, January 2010) applied a penis extender for 4-6 hours per day during the first 2 weeks and then 9 hours per day until the end of the third month. The results measured after the treatments were 1.7 cm in growth in flaccid and erected state.

Studies have also shown the penis extenders to be effective in treating penile curvature and consequences of Peyronie’s disease.

Medical Extender for the Treatment of Peyronie’s Disease

Levine with his coworkers reports in his two articles Medical Extender for the treatment of Peyronie’s disease (published in Expert Review of Medical Devices, May 2008) and Penile traction therapy for treatment of Peyronie’s disease: a single-center pilot study (published in The Journal of Sexual Medicine, June 2008) an improvement of penile curvature caused by Peyronie’s disease by 10-45 degrees using prolonged external penile traction applied with a penis extender device. Ten men in the USA were treated with the device 2-8 hours/day for 6 months. Beside the reduction in the curvature, he also reports increased penile length (1 – 2.5 cm) and increased erect girth 0.5-1.0 cm. Erectile function has also improved. No adverse events including skin changes, ulcerations, hypoesthesia or diminished rigidity were noticed.

Use of Penile Extender Device in the Treatment of Penile Curvature as a Result of Peyronie’s Disease. Results of a Phase II Prospective Study.

Another study (published in The Journal of Sexual Medicine, February 2009) done by Dr. Gontero and his team in Italy on 15 patients reports similar results. Patients used the penile extender for at least 5 hours per day for 6 months. Reported decrease of penile curvature was 27-31 degrees on average after the 6 month period, while the increase of penis size was 1.3 cm and 0.8 cm in erect and flaccid state respectively. Results were re-measured 6 months after the completion of the treatment to verify they were permanent.

As you can see, most independent studies done to assess the efficiency of penis enlarger devices and treatments agree it is an effective method which brings desired results in penis enlargement without causing unwanted end results or undesired side effects in the process of treatment. Most of the studies also state the increase of penis size occurred both in length as well as girth of the penis in most men tested. At the same time, penis extenders have been proven to be very effective in correcting penile curvature as well.
