London - Women who want to delay motherhood have the best chance if they freeze their eggs in their early 20s, experts say.
The vast majority of women who go through the procedure do so in their late 30s – by which time they have very little chance of success.
Specialists are increasingly concerned that fertility clinics encourage women to delay motherhood for too long by offering them the safety net of egg freezing.
The longer they wait, the lower the chance of being able to start a family – yet two-thirds of women who freeze their eggs do not do so until they are over the age of 35.
The Royal College of Obstetricians and Gynaecologists said women who leave it too late will struggle to have a baby.
