A new, first-of-its-kind study has provided crucial data surrounding the chance of IVF success based on a woman’s age.
Published in The Medical Journal of Australia, the new research is the first to be based on repeated implantation cycles instead of single cycles, the Courier Mail reports.
According to the data, women who begin IVF aged between 30 to 34 have a 43.4 per cent chance of a live birth after just one cycle, while women aged between 40 to 44 have a 10.7 per cent chance.
The more cycles, the higher the success rate. Women in the 40 to 44 age bracket have a much higher success rate of 37.9 per cent by the eighth cycle, smh.com.au reports.
Study co-author and senior fertility specialist at IVF Australia Professor Michael Chapman told smh.com.au that the research provides “more hope” for women undergoing or considering IVF.
“So now I can tell a woman [who is 35]: ‘Chances of our first embryo transfer producing a baby are in the order of 32-33 per cent, but it’s highly likely you’ll have frozen embryos and so by the end of those frozen embryos your chances will be well above 50 per cent,” he says.
The research will be used to aid doctors giving advice on success rates to their patients.
The study took 56,700 women from Australia and New Zealand who began IVF treatment between 2009 and 2012 , and followed them until 2014 or their first IVF birth. It was led by Associate Professor Georgina Chambers, director of the University of New South Wales’ National Perinatel Epidemiology and Statistics Unit.
