Vitrification
Vitrification is an advanced cryopreservation technique for egg and embryos that based on the nature of the cryo-protectants used and an extremely fast cooling rate is able to generate a glass-like state preventing the formation of ice crystals during the process. Once stored in liquid nitrogen (-196 degrees Celsius) the cellular activity is essentially brought to a halt, allowing the oocytes/embryos to remain viable indefinitely. Patients having surplus good quality embryos besides the embryos selected for embryo transfer Those embryos can be vitrified in order to have extra chances, if required, of having a baby in subsequent embryo transfers without the need to undergo a new stimulation cycle.
