The vitrification flash-freeze egg freezing method requires absolute critical time exposure through many different solutions with very specific exposure times. Since the solutions are extremely concentrated and potentially toxic to the eggs, there is very little margin for error. The flash freeze procedure must be performed with exact precision, requiring special skills and concentration by the embryologist.

The conventional freeze program is a more gentle and gradual way to dehydrate the eggs and expose them to our specially developed freezing solutions. By using the principals of osmosis and membrane potential, the water inside the egg is gently dehydrated and exchanged for the cryoprotectant solutions used to prevent ice crystal formation. This physiologic process avoids “shocking” the egg by abrupt fluid changes using toxic concentrations of solutions. The eggs are stored in specially designed straws which are sealed as an extra precaution to prevent possible viral contamination.
