title: The effect of varicoceles on testicular blood flow in man.
abstract: OBJECTIVE
  To assess the effect of varicoceles on testicular blood flow in man.
  
  
  METHODS
  Testicular blood flow was measured in 248 consecutive men attending an infertility clinic and 34 fertile volunteers using color duplex ultrasonography.
  
  
  RESULTS
  The testicular blood flow of men with either clinical and/or subclinical varicoceles was not significantly different from controls without varicoceles.
  
  
  CONCLUSIONS
  Varicoceles do not significantly alter testicular blood flow in man.
