First successful report of freezing of mouse embryo’s. They actually survived after being frozen!
The first successful mouse embryo cryopreservation (CP) was reported independently from each other by two research groups in 1972. One year later, the birth of the first calf from a frozen embryo was published. The first human pregnancy from a frozen embryo was achieved with the same procedure used successfully for CP of mouse and cow embryos; Since then, both sperm and embryo CP have become routine procedures in human assisted reproduction (AR) and oocyte CP is being introduced into clinical practice and is getting more and more widely used.
