This new method of increasing penis girth involves the removal of strips of tissue (together with fat cells) from under the folds of the buttocks. These strips are inserted into each side of the penis.
The results are more stable and long term than fat injections.
The main problem is that (parts) of the inserted tissue may not survive. This can lead to curvature of the penis and asymmetry.
It can easily lead to complications, like infections and scarring, because the strips of tissue have to be grafted onto the penis. This is more involved than injecting fat cells. There are also large, sometimes painful, visible scars between the thighs and buttocks. Surgeons don’t have much experience with this method yet.
