EMBRYO CRYOPRESERVATION
Embryo cryopreservation is done to avoid the risks of multiple pregnancies or wastage of supernumerary embryos
Embryo cryopreservation is done to avoid the risks of multiple pregnancies or wastage of supernumerary embryos. Embryo cryopreservation is now done by the method of vitrification. Our own and other statistical data have shown that a greater percentage of embryos survive following vitrification compared to the older slow freezing method. Similarly, the pregnancy rate following the transfer of vitrified embryos is reaching that of the fresh embryo transfer
