Surgery is risky and may not work

Studies of surgeries to lengthen or thicken the penis have found mixed results in safety, whether they work (effectiveness), and patient satisfaction.

At best, surgery may give a slight increase in girth to the penis. Or surgery may add a slight appearance of increased length to the non-erect penis. But it does not change the actual length of the penis. At worst, surgery can cause complications such as infection, scarring, and loss of sensation or function.
