Women who freeze their eggs to extend their fertility run the risk of spending a lot of money for a treatment with a small chance of success.
So-called social egg freezing (SEF) can be used to put off childbearing or because a woman has not yet found a partner.
But the Royal College of Obstetricians and Gynaecologists (RCog) has warned that egg freezing does not guarantee future live births and there are storage limits for how long eggs can be kept frozen, currently 10 years in the UK.
Egg freezing is not available on the NHS apart from in certain circumstances, for example a woman undergoing medical treatment that may affect fertility.
