What is Cryopreservation?
The cryopreservation method has been in use for decades in various medical fields. Cryopreservation involves freezing biological material at extremely low temperatures, i.e., at -196°C/-321°F in liquid nitrogen. It entirely freezes all the cellular activities. Even it stops the biochemical reactions that may lead to DNA degradation and cell loss.
The cryopreservation technique is useful in freezing and thawing the eggs, sperms, or embryos utilized in the IVF or ICSI cycle. Also, we can use the cryopreserved sperms in the IUI fertility technique.
