While you can't do much to safely enlarge your penis, there are several things you can do to make you feel more confident about your body. The time it takes to see results, said to be a matter of weeks, depends on a man's body type, eating habits, overall health, genetics, and other factors. Scientific evidence supports some elongation by prolonged traction. However, there are also medical studies that indicate that the lengthening effects can be negligible.
