The most common technique involves cutting the ligament that attaches the penis to the pubic bone and performing a skin graft at the base of the penis to allow for the extra length. Professor Wylie says the surgery can result in an average gain in length to the flaccid penis of 2cm, but there will be no change to the size of the erect penis.
Furthermore, the erect penis won’t point as high as before the operation because the ligament which was cut no longer offers support.
“A lot of men who have this treatment don’t truly appreciate this loss of angle,” says Professor Wylie. “It can make sex quite uncomfortable. You’ve got to do a lot more manoeuvring with your partner. The advantage of a 2cm gain in flaccid length is far outweighed by the loss of angle of erection.” UK NHS 2015

“Some surgical techniques to increase penis girth involve injecting fat taken from another part of the body into the penis. Some studies have reported increases in circumference of 1.4-4cm.
However, studies that followed men up over a longer time suggest disappointing results, with complications including disfigurement, scarring, lumpiness and infection. Another method, still in its experimental stage, involves pulling back the skin of the penis to wrap a tube-like biodegradable frame filled with tissue cells around the shaft.
Professor Wylie says the use of biodegradable frames has had better results than fat injection. “The problem with injecting fat is that over time, the body will re-absorb the fat which can result in a return to the penis’ original size,” he says.” UK NHS 20/04/2015

Surgery to increase penis girth
“Surgery to increase the girth of the penis can involve injecting fat taken from elsewhere in the body into the penis.
There’s a risk that the penis may look uneven or lumpy, and there may be scarring. The injected fat can also disappear over time.
Very little evidence has been published on the long-term effectiveness and risks of this technique.” UK NHS 04/04/2015

Surgery to increase penis length
“A study in 2006 found that this procedure led to an average increase of 1.3 cm in penis length. However, only 35% of men who had the operation were happy with the results.” [emphasis added] UK NHS 04/04/2015
