title: [Evaluation of radiation damage to the sperm DNA of radar operators].
abstract: OBJECTIVE
  To evaluate the inflicted by radar electromagnetic radiation to the sperm DNA of radar operators.
  
  
  METHODS
  Sperm concentration, viability, motility, sperm abnormality were determined by routine sperm analysis and sperm chromatin structure assay (SCSA) in the highly exposed group(n = 88), lowly exposed group(n = 143) and control group(n = 39).
  
  
  RESULTS
  Sperm motility, viability of the highly exposed group reduced compared with that of the lowly exposed group and control group, while sperm abnormality increased. The COMP alpha reduction of the highly exposed group indicated that the highly exposed group had a medium fertility potential. The multifactor variable analysis showed that daily working time was a dangerous factor in sperm abnormality and abstinence time was a dangerous factor in the parameter of SCSA.
  
  
  CONCLUSIONS
  Radar radiation inflicts damage to male reproduction system and it is important to take protective measures.
