Ads for penis-enlargement products and procedures are everywhere. A plethora of pumps, pills, weights, exercises and surgeries claim to increase the length and width of your penis. However, there's little scientific support for nonsurgical methods to enlarge the penis. And no reputable medical organization endorses penis surgery for purely cosmetic reasons. Most of the techniques you see advertised are ineffective, and some can damage your penis. Think twice before trying any of them.
