Penis length surgery involves cutting the ligament with which the penis is attached to the pubic bone and grafting added skin to the base to increase length. This will increase the size of the flaccid penis by up to 2cm, but it doesn’t affect the size of the erect penis. The cut ligament may also not provide the support it originally did, which means that you might find your erections less satisfactory as a result. There is also a risk that this type of surgery may cause the side effect of pain during sex.
According to Dr. Tobias Kohler, assistant professor of urology in Southern Illinois University School of Medicine, “Most guys would be proud to know that their penis is twice as long as they think it is.” This is because half of the length of the penis is actually inside a man’s body. Men do not commonly see the entire length of the penis because it is attached to the pubic bone and tucked up inside the pelvis.
