The method reduces ice crystals that form during cryopreservation and affect spermatozoon structure
Cryopreservation is a freezing method that stores spermatozoa to be used for reproduction. Although it is a widespread process, its main issue is the ice formation that occurs during said process, which ends up affecting sperm structure and quality. In order to diminish this harm, usually permeable cryoprotectants are used, which are substances that penetrate tissues and act inside cells in order to stop ice crystals from forming when temperatures go down.
