Penis enlargement, sometimes euphemistically called male enhancement, refers to an assortment of techniques intended to increase the girth, length, or erectile rigidity of the human penis.
Procedures range from manual exercises to stretching devices and surgical procedures, with reports of successes and failures around the world. While some techniques are known to be outright hoaxes, others can produce some measure of success. Often, in the advertising of fraudulent products, the distinction between temporary enlargement, i.e. erection, and permanent enlargement is deliberately muddied.
