title: [Study on sperm quality of the soldiers influenced by reinforced training].
abstract: OBJECTIVE
  To investigate the correlation between abnormal sperm parameters and reproductive hormones and reinforced training.
  
  
  METHODS
  Epidemic investigation were done between two different groups by determining endocrine hormone and standard clinical sperm analysis.
  
  
  RESULTS
  Comparison between reinforced training group and non-training group showed decreased sperm velocity but no change on sperm moving form, increased teratism sperm percentage but no change on sperm number, decreased plasma testosterone but no change on LH.
  
  
  CONCLUSIONS
  Reinforced training has correlation with weak part of sperm parameter analysis and reproductive hormones.
