Penile Prosthesis - Penile Pump Implant
Penile prostheses (also called penile implants) are devices that are placed completely inside your body. They produce a stiff penis that lets you have normal sex. Penile implants are a good treatment choice for some men.
With an inflatable implant, fluid-filled cylinders are placed lengthwise in the penis. Tubing connects these rods to a pump that is placed inside the scrotum (the sac that holds the testicles). When the pump pushes fluid into the cylinders, they make the penis hard. Inflatable implants are the most natural feeling of the penile implants, as they let you control firmness and size.
In the simplest inflatable implants, the pump moves a small amount of fluid into the cylinders for erection then out again when erection is no longer needed. These devices are often called 2-part (or 2-component) penile implants. One part is the paired cylinders and the second part is the scrotal pump.
The 3-part inflatable penile implant is the state of the art in penile prosthetic surgery. It has paired cylinders, a scrotal pump, and a fluid reservoir in the belly. With these three-part devices, a larger volume of fluid is pumped into the cylinders for erection and out of the cylinders when erection is no longer needed. It is as close as it gets to normal sensation and feeling/comfort.
