A Penis Enlargement Technique That Works—And Is Only Kind of TerrifyingCassie Murdoch2/03/12 12:15amFiled to: Plastic surgeryPenisenlargementKoreaRestylanetweetshutterstock173EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThings are looking up for guys in the market for a penis enlargement. It appears some researchers from Korea University have found a method that is actually effective—and you don't even have to reply to some sketchy spam email to get it. The results of their research were recently published in the Journal of Sexual Medicine, and it turns out they used the same thing some ladies use for their faces, Restylane. After injecting Restylane into 50 men's penises, they found that there was average increase in circumference (or girth) of 4 cm. That increase still held 18 months later.The procedure was definitely not without its drawbacks. It required them to use a "hefty" needle to inject an average of 20.5 cc of the Restylane, which is a little under an ounce, using "a back-and-forth technique" into the deep soft tissue layers of the penis. Ouch! But it didn't end there, "the product was then ‘homogenized with a roller.'" That sounds deeply unpleasant—though it's definitely better than surgery and certainly faster than using a penis extender.
