What are penile implants (prostheses)?
Penile prostheses, or penile implants, are an important treatment option for men with ED who have an established medical cause for ED, fail to respond to nonsurgical treatments (such as oral medications, vacuum devices, injection therapy, etc.) and who are motivated to have surgery to improve erectile function. Penile implant requires a permanent surgical procedure that cannot be reversed. It is important that men talk to their doctor about the advantages and possible drawbacks of having the procedure.
This procedure replaces the spongy tissue (corpora cavernosum) inside the penis with rigid, semi-rigid, or inflatable cylinders (depending on which type of penile implant is chosen). In all penile prostheses, the surgically inserted components are totally concealed within the body. After a penile implant, when a man desires an erection, he is able to produce a rigid erection on demand that enables him to have sexual relations. Penile implants do not typically lengthen the penis.
