Abstract
Abstract A prosthesis adapted to be implanted in the penis for simulating an erection is disclosed herein. The prosthesis includes an elongated, malleable rod portion which is housed within a generally tubular, physiologically inert plastic body. The malleable rod portion enables the prosthesis to be conformed to a variety of shapes by bending or twisting same. During intercourse the prosthesis will maintain the penis in an erectile state, and afterwards the penis may be positioned and maintained by the prosthesis in a convenient, comfortable position.
