I also posted this in the "Sex and Adult" forum:
I actually do believe these findings are valid, as they rely on the technique known as "tissue expansion" which is how thousands of cut guys have restored most of their foreskin.
Anyway... some highlights:
Some non-surgical methods for increasing the length of the male sex organ do in fact work, while others are likely to result only in soreness and disappointment, a review of medical literature has shown.
Among the non-invasive methods, tested on 109 subjects, so-called penile extenders that stretch the phallus through traction were shown to be most effective.
One study reported an average increase of 1.8 centimetres (0.7 inches), while another measured an extra 2.3 centimetres (0.9 inches) in a flaccid state, and 1.7 centimetres (0.67 inches) when erect.
But the regimen for achieving these gains was arduous: six hours of daily traction over four months in the first case, and four hours every day over six months in the second.http://www.france24.com/en/20110419-yes-men-really-can-make-it-longer-study
