World Science report () before the age limit for the frozen embryos, States pursue different standards. In the United Kingdom, people can be your own frozen embryos stored for 5 years, if you want to extend the deadline you need to apply to government agencies. Spain is not the age of frozen embryos to make provisions.
Although people will not know exactly what can frozen embryos survive for many years, but there is evidence that they at least can maintain several decades or even 100 years of life, this will inevitably raises ethical issues. For example, if a couple stores in 50 years ago with a frozen embryo. 50 years after the embryo is implanted into the other female womb pregnancy was born, this will lead to a difficult to avoid ethical questions: for the frozen embryos couple of kids, the baby is their peers or younger people?
