title: [Effect of Percoll selection technique on normal morphology rate and acrosin activity of human spermatozoa].
abstract: OBJECTIVE
  To study the effect of Percoll selection technique on normal morphology and acrosin activity of human spermatoza.
  
  
  METHODS
  The sperm morphology and sperm acrosin activity were analyzed by automated sperm morphology analyzer(ASMA) and spectrocolorimetry.
  
  
  RESULTS
  The normal morphology sperm rate and acrosin activity were significantly increased after Percoll selection technique (P < 0.001).
  
  
  CONCLUSIONS
  Percoll selection technique could affect normal morphology sperm ratio and acrosin activity.
