The article reports on a study which examines whether Vitra-inga vitrified-oocytes or fresh oocytes are used in Brazil. It states that slow freezing and vitrification was used successfully to cryopreserve human embryos but cryopreservation of human oocytes yielded conflicting results. It notes that a meta-analysis showed that clinical pregnancy rate per transfer was 6% and the rate per oocyte thawed was 2.3%.

Indeed, cryopreservation of human zygote or embryos from the early cleaved-cell stage up to the blastocyst stage is a safe procedure, which has been carried out for the last 25 years. Experience with blastocyst cryopreservation...
