title: Culturing human embryos with and without glucose.
abstract: OBJECTIVE
  To review published data and to compare pregnancy rates (PRs) after culturing human embryos with and without glucose and phosphate.
  
  
  METHODS
  Comparison of results from various programs.
  
  
  METHODS
  Assisted Reproductive Technology Program.
  
  
  METHODS
  Patients were enrolled in various studies.
  
  
  METHODS
  Human embryos were cultured with and without glucose and phosphate.
  
  
  METHODS
  Pregnancy rates after different techniques of embryo culture.
  
  
  RESULTS
  Some studies reported higher PRs in patients undergoing IVF after embryos were cultured in media without glucose and phosphate versus media with glucose and phosphate. One study showed that PRs were lower when embryos were cultured in media lacking glucose and phosphate compared with media containing glucose and phosphate. Some studies have also shown similar PRs with the two types of culture media.
  
  
  CONCLUSIONS
  The PRs in IVF patients will not necessarily be enhanced if the embryos are cultured in media without glucose and phosphate.
