Older women struggling to have children could turn their "bad" eggs good again after a breakthrough by an Adelaide researcher.
University of Adelaide fertility researcher Dr Hannah Brown has found haemoglobin, known for making blood cells red, in healthy eggs but missing from damaged ones.
She took out the Women's and Children's Hospital Foundation's Young Investigator Award this week for adding haemoglobin back into "bad" mice eggs and undoing much of the damage.
"We hope that technology like this will be able to give these (less fertile) women an opportunity to mend their broken eggs," she told AAP on Thursday.
