What is embryo freezing?
Embryo freezing also called “cryopreservation” is a procedure wherein the embryos are frozen and stored in containers for future use. This procedure is done by first keeping the embryos in special freezing solutions for a fixed amount of time.following which they are immersed into liquid nitrogen which is at a temp of -196 deg C. Embryo freezing can be done at any stage of the embryo and once they are frozen they getarrested in that particular stage till they are thawed or warmed.
Embryo freezing is a well-established form of assisted conception treatment. An increasing number of IVF clinics worldwide are now able to freeze spare embryos for later transfer. The first frozen embryo baby was born in 1984. Embryo cryo-preservation allows multiple embryo transfers from a single egg collection and improves the chances of live-birth.
