title: Assessment of erectile and ejaculatory function after penile prosthesis implantation.
abstract: OBJECTIVE
  We investigated erectile and ejaculatory function after penile prosthesis implantation.
  
  
  METHODS
  A total of 121 patients were enrolled in the surgery group (SG) and 120 patients in the nonsurgery group (NSG). All subjects were evaluated by use of the following questionnaires: the erection function and intercourse satisfaction domains of the International Index of Erectile Function (IIEF) and the ejaculation domain of the Male Sexual Health Questionnaire (MSHQ-EjD). Comparisons were made between the SG and the NSG, by prosthesis types, and of postoperative periods and complication rates for each prosthesis type.
  
  
  RESULTS
  Differences in the erection function and intercourse satisfaction domains of the International Index of Erectile Function (IIEF-EF and IIEF-IS) between before and after treatment were significantly higher in the SG group than in the NSG group (p=0.02, 0.03, respectively). When comparing prosthesis types, differences in the erection confidence and intercourse satisfaction items between before and after surgery were significantly higher in the SG group (p=0.03, 0.04, respectively). In the comparison of each prosthesis type by postoperative period, differences in the IIEF-EF and IIEF-IS between before and after surgery were not statistically significant but the MSHQ-EjD domain after surgery was significantly lower in cases of >5 years (p=0.02, 0.03, respectively).
  
  
  CONCLUSIONS
  Subjective symptoms such as erectile confidence and erectile function were improved more in the SG group than in the NSG group, especially in the inflatable group. It appeared that there was no significant difference in improvement in ejaculatory function depending on the treatment method, but that ejaculatory function decreased as time passed.
