A fairly common way for surgeons to add volume in such areas of the body as the face and butt, fat grafting is also an option for the penis. Dr. Tim Neavin, a plastic surgeon in Beverly Hills, California, says that some surgeons have been doing penile fat transfer (also called composite augmentation phalloplasty) for decades. In this technique, a surgeon takes fat from the belly or inner thighs and injects it into the penis to increase girth.
Penis pumps and vacuums are popularly used as sexual aids to promote erections in men. They are also used by some with the intent of increasing penis size. These devices are placed over the penis (and sometimes the scrotum) and use suction to engorge the penis with blood. If used consistently over a long period of time, they can cause the skin of the penis to become "spongy" and have a thicker appearance.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there -- penis pills, creams, brutal stretching exercises, horrific-looking devices, and penis surgery. Almost none of it works. The few approaches that can work often have modest benefits and serious side effects. How serious? In some cases, erectile dysfunction-serious.
