How does penis enlargement surgery work?
There are two main types of penis enlargement surgery.
Penis lengthening surgery – this type of surgery makes the penis longer while it’s not erect (flaccid). To increase the length of the penis, a surgeon would cut one of the ligaments (suspensory ligament) which attach the penis to the hip bone (pelvis or pubic bone). This drops the angle of the penis, which makes it longer when it’s flaccid.
Penis lengthening surgery on average increases the length of the flaccid penis by 0.65-1.8cm. But, there’s no change to the length of the penis when it’s completely erect.
The suspensory ligament supports the penis whilst it’s erect. So, after penis lengthening surgery some men find it more difficult to penetrate their partner. Also, the angle of the penis when it’s completely erect will be lower.
Penis widening surgery – to widen the penis, a surgeon can take fat from other parts of the body and transplant it into the penis. Or, they can put implants into the penis to make it wider. On average, this type of surgery can increase the girth (circumference) of the penis by 1.5-3.35cm when flaccid or 1.2-2.75cm when erect.
Unfortunately, there are some drawbacks to this type of surgery. If you opt for a transplant of fat, over time the body can reabsorb the fat that’s been injected into the penis. This can make the girth of the penis smaller again. Also, some men experience scarring or changes in the shape of their penis.
