Cryopreservation is a process which is used to store biological materials like cells, organelles, tissue by freezing at low temperatures for an extended period. Different freezing strategies are used to cryopreserve biological materials for long term and slow down any metabolic processes which may damage it. Success rates in Assisted Reproductive Technology (ART) Labs depend on efficiency of cryopreservation processes, for potential future use of gametes and embryos. An efficient cryopreservation strategy will result in improved implantation rates and successful pregnancies.
