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 and foreskin size.[1] Techniques include surgery, supplements, ointments, patches, and physical methods like pumping, jelqing, and traction.[1]
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. Non-invasive methods have received little scientific study, and most lack scientific evidence of effectiveness.[1] However, limited scientific evidence supports some elongation by prolonged traction.[1][2] Some quack products may improve penis erection, mistaken by consumers for penis enlargement.
