title: Comparison of survival rate of cleavage stage embryos produced from in vitro maturation cycles after slow freezing and after vitrification.
abstract: Significantly more embryos survived the vitrification procedure compared to slow freezing (85.5% vs. 61.8%) in cleavage-stage human embryos produced from in vitro maturation cycles, suggesting that vitrification is more efficient than slow freezing for cryopreservation.
