After the first successful application of vitrification for embryo cryopreservation 15 years ago,
a rapid application of the method in domestic animal embryology was presumed. However,
although the advantages of vitrification (simplicity, cost efficiency, speed of the procedure)
were widely acknowledged, its use has been mainly restricted to experimental studies. For
commercial embryo transfer purposes, the traditional slow-rate or equilibrium freezing has
