Laboratories for assisted reproductive technology (ART) have successfully frozen sperm, embryos, and even ביצת יוני for some time now. However, success within this context is a relative term from a historical perspective. The freezing of sperm, for example, worked quite well for several decades with very few technological adjustments to the basic freezing protocols-this is because sperm do not have that much water in their composition-the more water there is the greater the likelihood that freezing damage will occur.
