Is egg freezing all it's cracked up to be?

Egg freezing is sold as a way for women to hack their fertility and buy some more time on the biological clock.Fertility companies are marketing the procedure as an insurance policy, but some experts argue it's better thought of as a lottery.Rates of egg freezing have almost doubled in recent years but the number of people coming back to use those eggs are staggeringly low and even then, there's no guarantee of a baby. Then there's the cost, between $5000-$10,000 per cycle.Alongside egg freezing, the AMH test, or egg timer test, is also being promoted as a way for women to take control of their fertility but the only way to know if you're fertile is to try and get pregnant.This episode sorts the science from the sell around egg freezing and fertility tests.Featured in this episode:Dr Tessa Copp, University of Sydney School of Public Health.
