Clinical Studies on Penis Extenders and Traction Therapy
Penis extenders, also called penile traction devices, are one of the only non-surgical methods of penis enlargement backed by peer-reviewed clinical research. The studies below demonstrate measurable, permanent length gains from consistent traction therapy.
Effect of Penile-Extender Device in Increasing Penile Size in Men with Shortened Penis: Preliminary Results
Objective:
The study aimed to evaluate the effectiveness of a penile extender device in increasing the penile size of men with a shortened penis. Shortened penis length can result from various conditions, including Peyronie's disease, prostate surgery, or congenital abnormalities. The study sought to provide preliminary data on the potential of penile extenders as a non-surgical treatment option.
Method:
This preliminary study involved a sample of men who were diagnosed with a shortened penis. Participants were instructed to use a specific penile extender device for several hours each day, over a period of six months. The device applied a consistent, gentle traction to the penis, aiming to stimulate tissue growth and increase penile length.
Results:
The preliminary results indicated a statistically significant increase in penile length among the participants. The average length increase observed was about 2.3 cm (0.9 inches) in the flaccid state and 1.7 cm (0.7 inches) in the stretched (erect) state. Additionally, the study noted an improvement in patient satisfaction and self-esteem, with participants reporting a better quality of life post-treatment. No severe side effects were recorded, though some participants experienced mild discomfort during the initial phase of device use.
Conclusion:
The study concluded that penile extenders could be an effective and safe method for increasing penile size in men with a shortened penis. The device was well-tolerated and showed promise as a non-surgical option for penile lengthening.

Penile Traction Therapy for Peyronie's Disease: Clinical Evidence
Summary:
Multiple randomized clinical trials have evaluated penile traction devices specifically for men with Peyronie's disease. Daily use of a penile traction device for 4 to 6 hours over 3 to 6 months reduced penile curvature by an average of 33% and increased erect penile length by 1.5 cm. Patients also reported improved erectile function and reduced pain.
Key finding:
Penile traction therapy is now recognized in clinical urology as a first-line, non-surgical treatment for Peyronie's disease. Effects on length and curvature are retained at follow-up.

Long-Term Efficacy of Penile Extender Devices for Penile Lengthening
Summary:
Follow-up studies tracking men using penile extenders for 12 months show average length gains of 1.5 to 2.3 cm with consistent daily use of 4 to 6 hours. Length gains were retained at 6-month follow-up after stopping device use, confirming permanent tissue lengthening rather than temporary swelling.
Key finding:
Penile traction is the only non-surgical penis enlargement method with documented permanent length gains. Surgical penile lengthening averages less and carries far greater risk.
How Epic Extender Builds on This Research
The Epic Extender is a high-tension penile traction device designed around the clinical findings above: consistent, measurable tension applied daily for 1 to 4 hours. The padded silicone base and angle straps make the long wear times required for results practical to actually maintain. The Epic Cups attachment reduces slippage and makes the tension consistent.
