What are the disadvantages of penile implants?

What are the possible risks, side effects and complications of penile implants?

Possible surgical, medical and device related risks and complications includes infection, erosion of the implant through the skin, urethra and small bowel intestine, colon, or injury to artery or vein of lower extremity, temporary severe pain in the surgical area and mechanical failure of the implant.
Loss of remaining spontaneous erectile ability will also occur after an implant and patients who have spontaneous functional erections should be aware of this occurrence.
Other risks of a general nature inherent in any type of surgical procedure such as bad reaction to anesthesia, contracting pneumonia if the procedure is performed under general anesthesia, phlebitis, or other dangers arising from existing heart problems are also potential complications.
Possible need for further surgery if a complication or dissatisfaction occurs following the initial implant.
