title: Uterine position change between mock and real embryo transfers.
abstract: OBJECTIVE
  This study was designed to assess the change in uterine position between mock and real embryo transfers.
  
  
  METHODS
  A total of 386 embryo transfer cycles were reviewed, and the uterine position was recorded at the time of mock embryo transfer and then again at the time of real embryo transfer.
  
  
  RESULTS
  Of 254 patients with an anteverted uterus at mock transfer, only 3 (1.2%) were found to have a retroverted uterus at actual embryo transfer. Of 132 patients with a retroverted uterus at mock transfer, 24 (18%) had an anteverted uterus at actual embryo transfer (p < 0.0001).
  
  
  CONCLUSIONS
  Routine ultrasound-guided embryo transfer is suggested when a retroverted uterus is found at mock embryo transfer, as there is a significant chance that the uterine position will change.
