title: A retrospective review of factors associated with vasovasostomies in United States military members.
abstract: BACKGROUND
  Men seeking a vasectomy should receive counseling prior to the procedure that includes discussion of later seeking a reversal. We sought to determine demographic factors that may predispose patients to possibly later seek a vasectomy reversal.
  
  
  METHODS
  All U.S. Military electronic health records were searched between 2000 and 2009 for either a vasectomy or vasovasostomy procedure code. Aggregate demographic information was collected and statistical analysis performed.
  
  
  RESULTS
  A total of 82,945 patients had a vasectomy of which 4,485 had a vasovasostomy resulting in a vasovasostomy-to-vasectomy rate of 5.04%. The average age at vasovasostomy was 34.9±5.0, with an average interval of 4.1±2.2 years. Men undergoing a vasectomy at a younger age were more likely to have a vasovasostomy. Various religions did have statistically significant differences. Within ethnic groups, only Native Americans [OR=1.39 (95% CI 1.198-1.614)] and Asians [OR=0.501 (95% CI 0.364-0.690)] had statistically significant differences when compared to Caucasians. Men with more children at the time of vasectomy were more likely to have a vasovasostomy.
  
  
  CONCLUSIONS
  Younger men, Native Americans, and men with more children at vasectomy were more likely to undergo a vasovasostomy. The reason for these differences is unknown, but this information may assist during pre-vasectomy counseling.
