title: Sexual function outcome following photoselective vaporisation of the prostate.
abstract: BACKGROUND
  There is little reported on sexual functional outcome following photoselective vaporisation of the prostate using the 120 W lithium triborate laser.
  
  
  OBJECTIVE
  The objective of this study was to evaluate changes in sexual function at 3 and 12 months following PVP.
  
  
  METHODS
  The primary outcome measures were changes in voiding parameters and changes in erectile function in the international index of erectile function (IIEF-5). Change in erectile function was defined as mild (<5 IIEF points) or major (≥5 points).
  
  
  RESULTS
  Results found that 75% of men had an IIEF-5 < 17 at baseline. At 3 months, the mean post-operative IIEF-5 score was unchanged compared to baseline (P = 0.13). A major decline in erectile function was seen in 12.4 and 24% of men at 3 and 12 months, respectively, and a major improvement in erectile function was seen in 8.3 and 6% at 3 and 12 months, respectively. There was no correlation in change in erectile function with urinary function, quality of life and loss of emission on orgasm. Loss of emission on orgasm was reported in 65% of respondents.
  
  
  CONCLUSIONS
  Significant changes in erectile function are observed following PVP although a cause and effect relationship remains unclear.
