Penis enlargement, or male enhancement, is any technique aimed to increase the size of a human penis. Some methods aim to increase total length, others the shaft's girth, and yet others the glans size. Techniques include surgery, supplements, ointments, patches, and physical methods like pumping, jelqing, and traction.
Surgical penis enlargement methods can be effective; however, such methods carry risks of complications and are not medically indicated except in cases involving a micropenis. Noninvasive methods have received little scientific study, and most lack scientific evidence of effectiveness. However, limited scientific evidence supports some elongation by prolonged traction.Some quack products may improve penis erection, mistaken by consumers for penis enlargement.
