One to 4 years after penile prosthesis implantation 52 men and 22 partners were interviewed personally. All except 4 patients were having intercourse on a regular basis. A quarter of the patients reported restriction in intercourse positions, possibly because of a smaller penis postoperatively, and 15 per cent reported decreased orgasm intensity. Six men had an undiagnosed prosthesis malfunction or they used an inadequate pumping technique, suggesting that prosthesis patients should be followed on a continuing basis. The 52 men had experienced 10 malfunctions with the prosthesis. Partial erections were reported by 69 per cent of the patients but this could be confirmed in only 1 of 10 with visual sexual stimulation testing. It is suggested that differences between prosthesis models are more a result of psychological, relationship and health factors than mechanical factors. Of the patients 79 per cent would undergo the operation again but only 59 per cent of the partners had no hesitations. The longer the postoperative period the more hesitations. A satisfaction score was used to measure patient satisfaction.
