Over the past 10 years, researchers have restored the fertility of female cancer patients who would otherwise have been left infertile after treatment, having been offered oocyte cryopreservation. The technique enables women to freeze their eggs and use them at a later time to conceive a child. Several babies have been born to cancer patients using this technique, which is no longer classed as experimental.
