Phalloplasty, or penis enlargement surgery, can lengthen the penis by up to 5cm and widen it by up to 2cm. With lengthening surgery, a low abdominal incision is made and ligaments are cut at the base of the penis. Fat grafts are taken from the waist or buttocks and are inserted under the skin of the penis to widen it. Patients can take six months to fully recover, though sexual intercourse usually can be resumed after six weeks. The results are permanent.
