A system and method for nonsurgical penile girth enhancement. Hydro-dissection creates a space along a length of the penis between Buck's Fascia and Darte's fascia. The filler material, such as hyaluronic acid, is injected into the space created and is modeled after injection. During the same procedure or a later procedure, additional spaces can be created and injected with the filler material, until the desired girth is obtained. The amount of filler material injected during any given procedure is limited to avoid challenging the lymphatics of the penis. By staging the girth enhancing injections, the risk of penile granulomas can be minimized, if not eliminated.
