A penile prosthesis is a device implanted into the erection chamber of your penis. These devices help produce an erection-like state, enabling you to have sex. The prosthesis doesn’t interfere with penile sensations, orgasms, ejaculation, or urination.
Two types of penile prosthesis are available:
Spectra implant
Your doctor implants a pair of semi-rigid cylinders inside your penis. You can easily lift the implant manually for intercourse, then push it down when not in use.
Inflatable implants
There are several inflatable varieties of penile prostheses. Your doctor implants a pair of cylinders into your penis and a pump inside your scrotum. He also inserts a reservoir of saline solution into your lower abdomen.
By squeezing and releasing the pump, the saline fluid moves into the cylinders to create an erection. When intercourse concludes, you can deflate the cylinders using the button on top of the pump and return your penis to its flaccid state.
