Women should not put off starting a family until their 40s in the belief they will simply be able to freeze their eggs and have them thawed later, a fertility specialist says.
Australian women are increasingly using assisted reproductive technology treatments, new health data has shown, but doctors warn that the chances of being able to achieve a live birth using a frozen egg were significantly less than from a frozen embryo.
About 3 per cent of Australian babies born in 2009 were conceived with in vitro methods, the 2012 Australian Institute of Health and Welfare report says, but the odds of a live birth dropped dramatically for women in their 40s.
For Australian women aged 45 and over using their own eggs, one live delivery resulted from every 800 initiated cycles of IVF in 2009, compared with one live delivery from every four initiated cycles in women aged 25 to 34. Women undergoing assisted reproduction treatment using donor eggs were generally older, the report said, with the average age being 40.8 years.
