How are embryos frozen?
Embryos can be frozen at any stage thanks to developing technological methods. Embryos are placed in special carrier apparatus after undergoing various processes in a protective solution. After this stage, it is frozen in liquid nitrogen at -196 degrees and safely stored in compartments specially allocated to each patient. Frozen embryo cells are removed from liquid nitrogen when they are to be thawed. These cells are then dissolved at appropriate temperatures and solutions. Then, the embryos taken to a special culture medium are put into special devices that mimic the mother’s womb called incubators. If the embryo is in good condition, it is transferred.
