title: [Nitric oxide and cytokine levels in the seminal plasma of infertile men].
abstract: OBJECTIVE
  To evaluate the effect of nitric oxide (NO), TNF alpha, IL-6, IL-8 on the pathogenesis of infertile men.
  
  
  METHODS
  NO, TNF alpha, IL-6 and IL-8 levels were assayed in 80 infertile men and 26 normal men.
  
  
  RESULTS
  The levels of NO, TNF alpha, IL-6 and IL-8 in infertile men were all significantly higher than those in controls (P < 0.01 or P < 0.05). NO was positively correlated with TNF alpha, IL-6 and IL-8 (P < 0.01).
  
  
  CONCLUSIONS
  NO, TNF alpha, IL-6 and IL-8 might play an important role in the pathogenic process of infertile.
