Penis enlargement surgery, also known as phalloplasty, is a procedure to increase the size of the penis. There are two main types of surgery: one aims to increase the length of the penis, and the other aims to increase the girth (width). These surgeries are considered cosmetic procedures and are usually not covered by insurance.

A penile prosthesis is a device that is surgically implanted into a penis to allow a man to achieve an erection. It is typically used when other treatments for erectile dysfunction have failed. There are two main types of penile prostheses: inflatable devices and semi-rigid rods.

As with any surgery, there are risks involved. These can include infection, bleeding, nerve damage, and complications from anesthesia. Specific to penis enlargement surgery, there can also be dissatisfaction with the results, decreased sensation, and issues with sexual function.

An inflatable penile prosthesis consists of two inflatable cylinders placed in the penis, a fluid reservoir under the abdominal wall, and a pump inside the scrotum. The man squeezes the pump to inflate the cylinders with fluid and achieve an erection. A semi-rigid penile prosthesis consists of two semi-rigid rods that are implanted into the penis. The rods can be bent into an erect or flaccid position.
