When this ligament is cut, the penis appears longer because more of it hangs down. Although some surgeons offer cosmetic penis enlargement using various techniques, it's controversial and considered by many to be unnecessary and in some cases permanently harmful.
There aren't enough studies of penis-enlargement surgery to give an accurate picture of risks and benefits. These usually contain vitamins, minerals, herbs or hormones that manufacturers claim enlarge the penis. None of these products has been proved to work, and some may be harmful. However, there's little scientific support for nonsurgical methods to enlarge the penis.
