London: A healthy baby has been born from a frozen embryo that is twenty years old, potentially giving women the chance to put off motherhood until their forties or fifties.

It is the longest time a fertilised egg has been stored before developing into a healthy baby, reports the Daily Mail.

The newborn`s 42-year-old mother, who lives in the US, had undergone ten years of IVF but was unable to conceive.

But last year a frozen embryo - created by another couple - was implanted into her womb and in May she gave birth to a boy weighing 6lb 15oz.

The embryo was created with four others when the couple were having successful IVF treatment in 1990

When one was successfully implanted, they donated the other four for ``adoption`` and they were frozen.
