Treating Erectile Dysfunction Through Surgery
Surgery for erectile dysfunction usually has one of three goals:
- Implant a device that can cause the penis to become erect
- Reconstruct arteries to increase blood flow to the penis
- Block off veins that allow blood to leak from the penile tissues.
Implanted Devices
Implanted devices used in the treatment of erectile dysfunction include prostheses, malleable implants, and inflatable implants.
- Prostheses can restore erection in many men with erectile dysfunction. Possible problems with these implants include mechanical breakdown and infection, although mechanical problems have diminished in recent years because of technological advances.
- Malleable implants usually consist of paired rods, which are inserted surgically into the corpora cavernosa. The user manually adjusts the position of the penis and, therefore, the rods. Adjustment does not affect the width or length of the penis.
- Inflatable implants consist of paired cylinders, which are surgically inserted inside the penis and can be expanded using pressurized fluid. Tubes connect the cylinders to a fluid reservoir and a pump, which are also surgically implanted. For this type of treatment, the person inflates the cylinders by pressing on the small pump, located under the skin in the scrotum. Inflatable implants can expand the length and width of the penis somewhat. They also leave the penis in a more natural state when not inflated.
