Picture of rigid penile implant
Picture of rigid penile implant. Two rigid cylinders have been placed into the penis. This type of implant has no inflation mechanism but provides adequate rigidity to the penis to allow penetration.

Picture of the three components of inflatable penile implant.
Picture of the three components of inflatable penile implant. This inflatable penile device has three major components. The two cylinders are placed within the penis, a reservoir is placed beneath the rectus muscle, and the pump is placed in the scrotum. When the pump is squeezed, fluid from the reservoir is transferred into the two cylinders, producing a firm erection. Squeezing the top of the pump causes a reversal of flow of the fluid from the cylinders back into the reservoir.
