A prospective, multi-center, observational registry to be conducted at multiple sites throughout the United States and Canada, to collect "real-world" penile prosthetic outcomes according to investigators' standard of care. Using questionnaires as well as electronic data collection, investigating physicians will prospectively measure patient responses at regular intervals over a one- to five year period. The physician researchers have identified key metrics for the study including effectiveness, durability, complications, and patient satisfaction; quality of life will also be analyzed, being defined through several validated patient surveys.
