The physician can implant one of two types of penile devices:
- Malleable implant: This device consists of two rods that are placed in the erectile tissue (corpora cavernosa).
- Inflatable implant: A self-contained, fluid-filled system composed of two cylinders. An inflatable implant comes in two- or three-piece models, including a reservoir and pump.
Malleable implants produce a permanently firm penis, while the inflatable implants produce a controlled, more natural erection. Using a malleable implant, the patient can simply move the penis into the desired position.
With an inflatable implant, the patient presses a pump button in the scrotum. The pump transfers fluid from the reservoir to the cylinders in the penis, inflating them and causing an erection. The patient can restore the penis to a flaccid state by pressing a deflation valve at the base of the pump, which returns the fluid to the reservoir.
Implants enable men with erectile dysfunction to have satisfactory erections for sexual activity. Men with implants should still be able to have orgasms if they were able to before the surgery.
