A 50-year-old woman who desperately wants to become a mum is advertising for an IVF donor.
Megan Callaghan, who turns 51 in June, is seeking a woman aged 34 or younger to donate eggs.
She believes finding a donor is her last shot at motherhood.
"I have always wanted to be a mum, it just hasn't happened," she was quoted as saying in the Herald Sun.
"Life passes by so quickly, one minute your are 20 and the next you are 50."
Some doctors warn that older mothers face higher risk of miscarriage, premature labour and other complications.
But Ms Callaghan's doctor, Prof Michael Chapman from IVF Australia, said his clinic treated women up to 51.
"This is because that is the average age of natural menopause," he said.
Monash IVF Prof Gab Kovacs told the Herald Sun it was not a medical issue for a woman in her 50s to become a mother, but there were ethical and moral decisions involved.
"The problem is ... looking after the child - when the mother is 70, will she feel like driving around picking them up from their high school formal?" he said.
