title: The incidence of chronic scrotal pain after vasectomy: a prospective audit.
abstract: OBJECTIVE
  To assess the extent of scrotal pain in men before and after vasectomy, to produce accurate data for the benefit of men considering this procedure, and hence improved informed consent about the outcomes, as chronic scrotal pain after vasectomy is a poorly quantified clinical problem.
  
  
  METHODS
  Between November 2004 and January 2006 nine surgeons carried out vasectomies in 625 men (mean age 39.9 years, sd 5.6) under local anaesthesia. A questionnaire was devised to establish the presence of any scrotal or testicular pain, and to characterize this discomfort; 6 months after the procedure a modified version of the same questionnaire was administered.
  
  
  RESULTS
  In all, 593 (94.7%) men returned the preoperative questionnaires and were entered into the study; 488 (82.2%) of these completed the follow-up questionnaire, giving a mean (sd) follow-up of 6.8 (1.6) months. In all, 65 men reported new-onset scrotal pain at 7 months (14.7%). The mean visual analogue score for this pain was 3.4/10. Four men (0.9%) in the responding group described pain after vasectomy as 'quite severe and noticeably affecting their quality of life'.
  
  
  CONCLUSIONS
  At 7 months after vasectomy about 15% of previously asymptomatic men have some degree of scrotal discomfort. These early data indicate that chronic scrotal pain after vasectomy is a genuine entity, but a longer-term follow-up in this group will be important to allow further evaluation of how this pain develops with time.
