title: Outcome of intracytoplasmic sperm injection in relation to the meiotic pattern in patients with severe oligoasthenozoospermia.
abstract: OBJECTIVE
  The aim of the study was to evaluate the intracytoplasmic sperm injection outcome in a selected group of patients with oligoasthenozoospermia in relation to the results obtained from their meiotic analysis.
  
  
  METHODS
  Retrospective clinical study.
  
  
  METHODS
  An assisted reproduction service and a university department.
  
  
  METHODS
  One hundred thirty-seven men with oligoasthenozoospermia grouped in relation to their meiotic pattern.
  
  
  METHODS
  Two hundred twenty-four intracytoplasmic sperm injection cycles from 137 men with oligoasthenozoospermia in whom diagnostic meiotic analyses had been performed.
  
  
  METHODS
  Fertilization, pregnancy, implantation, and abortion rates.
  
  
  RESULTS
  There were no significant statistical differences in fertilization, pregnancy, implantation, or abortion rates among the three groups studied.
  
  
  CONCLUSIONS
  No statistically significant differences in fertilization, pregnancy, implantation, or abortion rates were found in patients with oligoasthenozoospermia in relation to the meiotic pattern.
