If other forms of therapy have been unsuccessful in resolving your erection difficulties, your doctor might refer you to a urological surgeon for a surgical procedure. According to eMedicineHealth.com, such procedures usually are undertaken to accomplish one of three goals:
Implantation of a prosthetic device in the penis. Such a device is usually either malleable or inflatable. With a malleable prosthesis, the man can physically manipulate his penis into an erect or semi-rigid position suitable for intercourse. For an inflatable prosthetic, two cylinders are implanted within the penis along with a reservoir placed beneath the tissue of the lower abdomen and a pump device in the scrotum. When the pump is activated, it draws fluid from the reservoir to fill up the penile cylinders, thus creating an erection.
Reconstruction of the arteries within the penis to increase blood flow, thus making it easier to achieve erection.
Blocking off veins within the penis that carry blood away, thus allowing an erection to be maintained.
