Cryoprotectant

A cryoprotectant is a chemical compound that prevents damage to cells during freezing, thereby maintaining its viability. Cryoprotectants are used during cryopreservation techniques, a method of cooling and storing eggs, embryos, and sperm.

The use of cryoprotectants ensures that the eggs, embryos, or sperm are not damaged during the freezing process and are preserved for future pregnancy attempts.
