How are embryos frozen and stored after an IVF cycle?
EMBRYO DONATION - Facts About EmbryosVery carefully! During the freezing process, even under the stringent protocols used by IVF labs, embryos must survive the dangers of ice formation, extreme changes in temperature, pH and the concentration of electrolyte in their environment, as well as transmembrane water movement. The cells of embryos, like other living tissue, contain water. Water forms sharp ice crystals and expands as it freezes, which would cause the embryo to burst if it were not removed first.

Pacific Fertility CenterThe air that we breathe contains a gas called nitrogen. This gas makes up about 78% of the air around us. If nitrogen gas is cooled, it becomes liquid at –1960C. This liquid is very stable and easy to work with. In the laboratory we have large tanks filled with liquid nitrogen in which we store frozen embryos. Each tank, actually called a DEWAR, is in many ways like a large thermos flask. It is vacuum lined and has a narrow opening to slow the evaporation of the nitrogen.
