  To compare the outcome of assisted reproduction in day 2 versus day three embryo transfer.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  A total of 927 consecutive embryo transfers for IVF and ICSI cycles including 626 embryo transfers on day 2 and 301 on day 3.
  
  
  METHODS
  IVF and ICSI.
  
  
  METHODS
  Clinical pregnancy rate.
  
  
  RESULTS
  There is no significant difference in the pregnancy rate between ET on day 2 (50.9%) and ET on day 3 (50.5%).
  
  
  CONCLUSIONS
