The sperm can be successfully live for almost 40 years with the help of this frozen process. After collecting the sperm sample, it is placed on a warming block maintained at 37°C to liquefy. These sperm cells will be kept in liquid nitrogen at -196 c and the quality of the sperm is also maintained with the sperm freezing process.
