title: Bed rest after embryo transfer: a randomized controlled trial.
abstract: OBJECTIVE
  To determine whether bed rest after embryo transfer leads to improved pregnancy rates (PR).
  
  
  METHODS
  Randomized controlled trial.
  
  
  METHODS
  University reproductive health clinic.
  
  
  METHODS
  Women undergoing IVF.
  
  
  METHODS
  Patients undergoing 164 cycles of IVF were randomized to 30 minutes of bed rest after embryo transfer or immediate discharge from the clinic.
  
  
  METHODS
  Clinical PR defined by visualized fetal heart beat and ongoing PR defined by viable intrauterine gestation beyond 11 weeks.
  
  
  RESULTS
  The clinical and ongoing PR for both groups were 50% and 46.3%, respectively, with no statistically significant difference between the two groups.
  
  
  CONCLUSIONS
  Thirty minutes of bed rest after embryo transfer does not improve PR.
