30 days of penis extender (approx 1500g, 3-4 hours per day,5 days on, 1 day off) no additional penis enlargement technique was applied such as jelqing, supplements, dermal applicants, etc…
Statistically, the length (erection) was improved by at least one quarter inch. Over time the result proved to be permanent. While girth appears to have improved as well, it is not statistically significant (given standard deviations) that it has permanently increased. However it seems likely that over time the result may prove to be statistically significant, additionally, stretching is not meant to increase girth alone. It has also been thought that when stretching the penis, it may actually lose girth, but this is even further from the truth. If there is a difference in girth at all it is much more likely to be on the larger side. Reason is likely due to the increased blood flow and vascularity caused by stretching.
