This animation sequence shows how a penile prosthesis device works. A penile prosthesis or penile implant is a surgical treatment option for men with erectile dysfunction. It is appropriate for men whose impotence is not treatable by less invasive solutions such as medication or men who opt not to use more conservative therapies such as pills (Viagra, Levitra, Cilias), MUSE tablets or tri-mix penile injections. A penile implant is placed surgically by a urologist. Dr. LeRoy Jones at Urology San Antonio performs this procedure and is one of the most experienced penile implant surgeons in the world based on the number of surgical cases performed.
