How the Internal Penile Prosthesis Pump™ Works During Sexual Activity

When a man is sexually aroused, all he has to do is squeeze the pump between the thumb and index finger, and an erection occurs. The penis looks and feels so normal (because of our minimally invasive surgical scrotal technique) that many patients report that even after sexual activity, a new partner could not tell that an Internal Penile Prosthesis Pump™ was present. Our surgical approach allows us to hide all of the components of the penile pump into the scrotal sac and the incision is concealed by the midline raphe of the scrotal skin.

When the erection is no longer desired, the patient squeezes and holds the pump, which releases the fluid back into the reservoir and brings the penis back to a flaccid state. The patient controls the duration of the erection. If a patient has an orgasm too quickly, the erection is not lost, and the patient is able to maintain it until his partner is satisfied.

How is the Penile Pump Placed?

In our center, it is an outpatient procedure, which usually takes less than one hour, and can be performed under local, epidural, spinal or general anesthesia. The complete Internal Penile Prosthesis Pump™ is placed through a very small minimally invasive opening, usually an inch long, in the scrotal sac. This is a breakthrough when compared to previous techniques, which made much larger openings that required longer and a more painful healing process. The skin on the penis itself is never opened so that there are no visible scars. This provides the patient with the best cosmetic outcome and concealment of the scar when compared to all other surgical approaches.

How Does it Look and Feel?

After complete healing, men with an Internal Penile Prosthesis Pump™ are very comfortable and report that they do not feel that there is something inside. Sexual activity can commence 3 to 4 weeks after the procedure. The penis looks and feels so natural that patients can engage in any activity including scuba diving, skydiving, bicycling, horseback riding, and wrestling. Grandfathers report that grandchildren can sit on their lap without worrying that the children will feel or notice anything unusual.
