I got my
SG last week - but still, I do some research on its efficacy.
Digging the web I bumped into collection of scientific experiments related to urology field.
One of them discus the efficacy of “Daily penis stretching technique”.
The bottom line is that using an
extender device for 4 months gave an average length gain of 1.8 cm (0.7 inch) and varied from 0.5 cm up to 3.0 cm (0.2-1.2 inch).
Check out this article and look for experiment P-155.

So I guess the answer is YES - it works...
