(TELEGRAPH) — Women could have the opportunity to give birth with their own eggs later in life thanks to the discovery that they possess a potentially “unlimited” supply of them, scientists have discovered.

Their ovaries contain stem cells which can “spontaneously” generate into immature eggs in the laboratory, according to the American team.

The prevailing wisdom has been that women have a finite number of eggs, that gradually diminish in number and quality until the menopause.

But British experts said the findings, published in the journal Nature Medicine, “re-write the rule book” on this point and amounted to “a potentially landmark piece of research”.
