During slow freezing, the temperature of the eggs, sperm, or embryos is lowered using a computer-controlled rate in a series of steps, to a very low temperature.

In vitrification, or flash freezing, the temperature of the eggs, sperm, or embryos is lowered very rapidly to an extremely low degree. This solidifies the sample into a glass-like state and avoids the risk of ice crystals forming.
