Embryo vitrification using a novel semi-automated closed system yields in vitro outcomes equivalent to the manual Cryotop method

STUDY QUESTION: Can the equilibration steps prior to embryo vitrification be automated? SUMMARY ANSWER: We have developed the 'Gavi' system which automatically performs equilibration steps before closed system vitrification on up to four embryos at a time and gives in vitro outcomes equivalent to th...
