title: Birth after 12 hours of oocyte refrigeration.
abstract: OBJECTIVE
  To assess cycle outcome after oocyte refrigeration.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Private IVF center.
  
  
  METHODS
  One couple in a donor oocyte program.
  
  
  METHODS
  Intracytoplasmic sperm injection and blastocyst culture after refrigeration of oocytes for 12 hours.
  
  
  METHODS
  Birth.
  
  
  RESULTS
  Fourteen two-pronuclei zygotes from 17 metaphase II refrigerated oocytes resulted in transfer of two blastocysts at day 5 and cryopreservation of six excess embryos at day 6. The patient delivered one healthy male baby after 38 weeks' gestation.
  
  
  CONCLUSIONS
  The successful outcome of oocyte refrigeration indicates that this protocol could be useful in circumstances in which a delay in obtaining spermatozoa arises.
