Research has found that when a doctor honestly reassures a guy that his penis is average-sized, he is likely to stop searching for surgery. Therefore, it is important to have a thorough consultation with an accredited plastic surgeon about the possible complications of penile enlargement surgery, which may include bruising, bleeding, swelling, skin incision separation, infection, loss of the erect upward angle of the penis, loss of thickness, detachment of the graft or failure of the graft to take, nerve injury or erectile dysfunction.
