An IVF cycle produces a number of viable embryos. Those that aren’t immediately transferred back to the patient are placed in cryostorage by lowering their temperature to that of liquid nitrogen (-196°C). At this temperature, embryos can be stored until they are needed for later transfer. The vitrified embryos can be used in case of repeated cycles and the overall cumulative rate is higher.
It is extremely useful for vitrification of unfertilized eggs, as they contain a high amount of water. Additionally, vitrification is being explored for tissue preservation, as there is thought to be less overall tissue damage from the vitrification process.
Unlike previous slow freeze methods, which took up to two hours to lower the embryo to the correct temperature, vitrification takes just a few minutes, generally less than 1 minute. The embryo is suspended in a very small volume of fluid on the end of a small flat specialised vitrification device. The device with the embryo is lowered onto a metal block that has been cooled by liquid nitrogen where the fluid containing the embryo hardens into a small “glassy” bead.
Most IVF clinics are adopting this new technique of embryo freexing because of it’s enormous benefits to both hoapital/ clinics and patients.
