For most men, self-concept and feelings of worth are intricately linked to the ability to attract a sexual partner and to perform appropriately. A disturbance in sexual performance can lead to feelings of worthlessness, impaired self-concept, and depression. Urologists have tried endless numbers of therapeutic techniques to help men with impotence. Drawing on the new technology used in the development of silicone breast prostheses, Small and colleagues,1 in 1975, reported the use of paired penile implants composed of an exterior of medical grade silicone rubber with a silicone sponge core as corpora cavernosa implants for producing penile rigidity.Many other semirigid penile prostheses have been developed in the United States, Europe, and Japan. All have utilized varying designs and materials. Semiflexible rod prostheses of the Finney design,2 the Jonas siliconesilver prosthesis,3 and the silicone prosthesis (Gerow design)4 have gained popularity. Scott et al5
