RestoreX™ has been evaluated in patients who have undergone radical prostatectomy causing penile shortening : on average, these patients recovered 1.6 cm of penis length after 6 months' treatment.
In these randomized clinical studies, an improvement in erectile function was also noted.
The RestoreX™ has not been studied to increase penis length and we refrain from communicating information when it has not been validated by prospective, randomized clinical studies. We do know that RestoreX enables lengthening of small yards (between 1 and 2 cm) and that this works when used regularly over a period of more than 3 months, but we cannot affirm or prove it.

Study summary
OBJECTIVE
RestoreX™ is a novel penile traction therapy device, with randomized controlled data demonstrating improvements in penile length and erectile function after 30-90 minutes of daily use in men with Lapeyronie's disease.
We sought to determine whether similar improvements could be achieved after prostatectomy.
MATERIALS AND METHODS
Men after prostatectomy were randomized to a control group or one of two penile traction therapy protocols for 6 months, followed by a 3-month open-access phase.
The present study presents data from the randomized phase.
The primary endpoint was changes in penile length in extension; secondary endpoints were changes in International Index of Erectile Function (IIEF) scores, adverse events, satisfaction and subjective measures.
RESULTS
Overall, 82 men (mean age 58.6 years) were randomized with data available at 6 months for 25 control group controls and a further 30 controls treated with penile traction therapy.
At 6 months, penile traction therapy resulted in:
- better improvements/preservation of penile length (+1.6 vs. +0.3 cm, p <0.01)
- erectile function (IIEF-Erectile function +0 vs. -6.5, p=0.03)
- sexual satisfaction with intercourse (IIEF-Satisfaction with intercourse +1 vs. -3.5, p <0.01)
- of overall sexual satisfaction (IIEF-Overall sexual satisfaction 0 vs -3, p <0.01).
The use of erectogenic therapies was lower in men treated with penile traction therapy (phosphodiesterase-5 inhibitors 86% vs. 94%, p=0.44; intracavernosal injections 19% vs. 50%, p <0.05).
More men treated with penile traction therapy reported satisfaction or improvement in penile length than control group controls.
Adverse events were transient and mild; 87% would choose to repeat the therapy, and 93% would recommend it to others.
CONCLUSION
The use of a novel penile traction therapy device results in significant improvements in both objective and subjective penile length after prostatectomy, as well as measures of erectile function, intercourse-related sexual satisfaction and overall sexual satisfaction.
External validation is warranted.
