This a very common question. The circumference or width of the male penis can be increased by serial fat grafting. Usually there is an increase of 1 to 2 inches. The length can be increased by detaching the base of the penis from the pubic bone. However, in the full/erect state the penis will no longer rise/lift up toward your head. You gain anywhere from 1/2 to 1 inch in length with the detachment. Hope this is of assistance.
