There are several surgical treatments, most of which carry a risk of significant complications. Procedures by unlicensed surgeons can lead to serious complications. Risky surgical treatments include subcutaneous fat injection, division of the suspensory ligament, and the injection of dermal fillers, silicone gel, or PMMA. The American Urological Association (AUA) and the Urology Care Foundation "consider subcutaneous fat injection for increasing penile girth to be a procedure which has not been shown to be safe or efficacious. The AUA also considers the division of the suspensory ligament of the penis for increasing penile length in adults to be a procedure which has not been shown to be safe or efficacious." Dermal fillers are also not approved by the US Food and Drug Administration (FDA) for use in the penis.

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.
