Penis traction (or penis extension) is a noninvasive method to lengthen the penis or to shape the curvature of the penis by using a special device that pulls at the glans of the penis for extended periods of time, on a daily basis.

It’s also increasingly used to treat Peyronie’s Disease (PD), which is a disease that results in penile curvature and causes substantial psychosocial stress.
The idea behind penis traction devices is that the use of mechanical traction and tissue expansion therapy results in alteration of connective tissue, which leads to expansion.
A penis traction device typically consist of a plastic support ring, a silicone band, and two dynamic rods. The therapy works by holding the penis in a kind of frame or cradle, while applying gentle and progressive traction forces that can be achieved by lengthening the metal extension rods.
Limited scientific evidence show some elongation by prolonged traction, although the lengthening effects are generally considered negligible.
