How is embryo freezing done?
Developing embryos are monitored in the laboratory.
Embryos deemed to be of suitable quality are selected.
Vitrification Using a rapid freezing technique called [name of technique], they are stored in special solutions at -196°C in liquid nitrogen tanks.
Once thawed, the embryos can continue their development from where they left off.
