[krī′ōpres′ərvā′shən]
a method of preserving tissues and organs in a viable state at extremely low temperatures.

cryopreservation

The reversible freezing of tissues–eg, packed RBCs and pre- and post-fertilization products, and autologous BM, often with glycerol for autologous BMT Reproduction medicine A technique for freezing cells to preserve for later use. See Frozen cells, in vitro fertilization.

The use of cryoprotectant agents (CPAs) in testicular cryopreservation protocols is a major step towards maintenance of cell viability after the tissue has been thawed because CPAs prevent some of the damage caused during the thawing process.

Thus, the determination of the dehydration degree necessary to prevent the onset of these effects appears to be a promising strategy for the success of cryopreservation techniques and subsequent establishment of germplasm banks (Raven & Havens, 2014).
A further advantage of cryopreservation over conventional storage techniques is that once in cryogenic storage there is virtually no risk of new microbial contamination and the development of disease.

Cryopreservation, which is the conservation of biological material at an ultra-low temperature (-196[degrees]C) in liquid nitrogen (ENGELMANN, 2011), is a useful technique for ex situ conservation, especially for species that either do not produce seeds or produce seeds that are recalcitrant (KACZMARCZYK et al.
