Embryo freezing is sometimes confused with egg freezing. While the egg is termed as the egg cells collected from a female, an embryo is known as the fertilized egg via the assistance of male spermatozoa. As a result, both freezing techniques are entirely dissimilar to each other in respect both the aims for freezing and the procedures.

The embryo freezing methods may be used for a period of over thirty years. Analyzing the embryo freezing in the medical terminology, a chemical is known as a cryoprotectant is frozen and the embryos are placed in storage in nitrogen filled liquid tank and at -196 degrees in each patient dedicated compartment. Since the tank is filled with nitrogen, it stops the embryos reacting or carrying out any cellular activity, it can be well-maintained for many years without declining its configuration.

Reason for Embryo Freezing?
