Outcome of closed blastocyst vitrification in relation to blastocyst quality: evaluation of 759 warming cycles in a single-embryo transfer policy
5 Jan 2011
Abstract excerpt
BACKGROUND: In order to optimize blastocyst cryopreservation, vitrification was introduced as the routine procedure instead of slow freezing. The outcome of a closed blastocyst vitrification system was evaluated in relation to the blastocyst score before cryopreservation in single embryo transfers (SETs). METHODS: Supernumerary blastocysts of IVF/ICSI patients with a fresh Day 5 transfer were vitrified using...
