title: [Is the stability of results in IVF possible?].
abstract: OBJECTIVE
  To evaluate quality control impact, in assisted reproductive medecine, in view of the stability of results.
  
  
  METHODS
  Prospective collection of all IVF cycles at the center of AMP at Antoine-Béclère hospital (Clamart), as well as pregnancy outcomes, from 2002 till 2006.
  
  
  RESULTS
  44.3% in the clinical pregnancy rate and 38.0% in the delivery rate per oocyte retrieval. These rates are stable during the five years studied. The rate of multiple pregnancy is of 30.7%, decreasing, with the decrease in number of transferred embryos.
  
  
  CONCLUSIONS
  Results are stable over five years duration. Quality control seems to be necessary.
