Penis enlargement is defined as all means and methods used to temporarily or permanently increase the size of the erect penis and its erectile tissue. Often the word is used in conjunction with a surgical penis enlargement, but it is not limited to surgical means and also includes manual training like jelqing, certain foods and supplements, devices and pumps to stretch the penis.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there -- penis pills, creams, brutal stretching exercises, horrific-looking devices, and penis surgery. Almost none of it works. The few approaches that can work often have modest benefits and serious side effects. How serious? In some cases, erectile dysfunction-serious.
