Secondly let me address the issue of traction devices, I also disagree with it removal from the topic of penis enlargement, 
 Some such devices are considered medical equipment, is one such device who has the backing of quite a few urologists and andrologists, while originally touted as a penile curvature correction device the applied traction proved to not only correct defects in penile tissue but to naturally allow tissue to be stretched and regenerated causing extension of the spongeous tissue called the Corpora Cavernosa which is inherently limited by how much it can be filled with blood when you get an erection, the goal of traction devices ( in a penis enlargement capacity) is to not only elongate the Corpora Cavernosa but to simultaneously improve girth by modifying the Corpus Spongium another elastic tissue designed to fill with blood and the Cavernosal Artery which feeds both the Corpora Cavernosa and Copus Spongium with blood, it's lengthening is directly proportional to both tissues because it is fibrous in nature and hence tied to its surrounding tissue. After all what good is a long  penis if it is not proportionally wide.
