Comparison of survival rate of cleavage stage embryos produced from in vitro maturation cycles after slow freezing and after vitrification.
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.
