Pros and cons from penile traction study
by George Atkinson
An Italian study into the effectiveness of penile traction devices has confirmed increases in length, but found no changes in girth. The new study, appearing in urology journal BJU International, was conducted by researchers from San Giovanni Battista Hospital, part of the University of Turin.
The new findings build on earlier research into extenders carried out by researchers from the Rush University Medical Center in Chicago that established positive outcomes from a study into their use to treat Peyronie's disease. That study found that "significant (10-45 degrees) improvement in curvatures is achievable" and that extender use was an effective first option for treating Peyronie's.
In the new phase II study, the researchers aimed to establish whether or not extenders could provide an increase in penile size. The subject group consisted of fifteen men who were counseled in how to use the penile extender correctly for at least 4 hours per day. Penile dimensions were measured at the beginning (baseline) and thereafter at 1, 3, 6 and 12 month intervals.
Additionally, the erectile function (EF) domain of the International Index of EF was administered at baseline and at the end of the study. Treatment satisfaction was assessed using an institutional five-item questionnaire.
After 6 months the researchers found that the mean gain in length was significant, meeting the goals of the effect size, at 2.3 and 1.7 cm (0.9 and 0.65 inches) for the flaccid and stretched penis, respectively. No significant changes in penile girth were detected, however.
Interestingly, the EF domain scores improved significantly at the end of study. The researchers noted that treatment satisfaction scores were consistent with acceptable to good improvement in all items, except for penile girth, where the score was either "no change" or "mild improvement."
The researchers concluded that 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.
