Performed on the halfway tumescent penis, jelqing is a manual manipulation of simultaneous squeezing and stroking the shaft from base to corona. Also called "milking", the technique has ancient Arab origins. Despite many anecdotal reports of success, medical evidence is absent. Journalists have dismissed the method as biologically implausible, or even impossible, albeit unlikely to seriously damage the penis. Still, if done excessively or harshly, jelqing could conceivably cause ruptures, scarring, disfigurement, and desensitization.
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.
