Traction is a nonsurgical method to lengthen the penis by employing devices that pull at the glans of the penis for extended periods of time. As of 2013, the majority of research investigating the use of penile traction focuses on treating the curvature and shrinkage of the penis as a result of Peyronie's disease, although some literature exists on the impact on men with short penises.
Many manufacturers market the products as dietary supplements because the products contain natural ingredients, including vitamins and minerals. When shopping for male enhancement products, read the label carefully. You might find that the product contains the same ingredients as those found in a multivitamin. You should also look at what the product does because not all supplements promise the same thing. Some shoppers want a male enhancement supplement that increases stamina, but some men want a product that only contains natural ingredients.
