Cryopreservation or freezing is a technique, in which the body cells/ tissue are frozen in ice for use at a later date. The frozen specimen is recovered intact when its time to use the by a process called thawing. This technique is now used quite commonly in fertility management and can be used to freeze eggs, sperms or embryos depending on the requirement. Freezing technology has evolved over time and the pregnancy rates using frozen sperms/ eggs/ embryos are as good as with fresh ones.
