Egg freezing is seen as a way to stop the biological clock, expand reproductive options and preserve the younger, possibly healthier eggs. And for many women looking to extend their childbearing years, it has become an increasingly attractive option.

Egg freezing is also important for women who undergo therapies, such as cancer chemotherapy or radiation, that will cause damage to their ovaries. Eggs can be retrieved and frozen prior to the therapy for use at a later date.
