where egg freezing was being pushed as the next frontier

New research asks for moderation

Women who want to freeze their eggs to use later in life are warned today that the procedure does not always work.
In a study of 11,000 cycles of IVF, experts found that using frozen eggs was successful 14 per cent less often than using fresh eggs.
Overall, cycles using frozen eggs led to a birth 43 times out of every 100.
Using fresh eggs, comparatively, was successful 50 times in 100.
The researchers said that frozen eggs may become damaged during the thawing process.

The procedure to freeze a woman's eggs does not always work, according to new research.

The study, published in the JAMA medical journal, was based on data from women who used donated eggs.
But the authors, from the Centre for Human Reproduction in New York, said that women who freeze their own eggs are likely to see even lower rates of success.
Dr Vitaly Kushnir, who led the work, said: ‘Egg donors tend to be carefully selected healthy, young, fertile women.
‘Women electively freezing their own eggs for social reasons to postpone fertility tend to fall in the middle, they are generally not infertile but most are not as young and healthy as carefully screened egg donors.


Therefore, these women need to be counselled appropriately about all their options and if they in the end choose to freeze eggs, should freeze a large enough number to have a good chance of a future live birth.’

Around 600 British women a year pay up to £30,000 to freeze their eggs until they want to start a family.
Information from private clinics shows that interest in egg freezing is increasing in some parts of the country by up to 400 per cent a year – with some women in their late teens and early 20s considering the procedure.
Dr Sue Avery, director of Birmingham Women’s Fertility Centre, said that the risks and benefits of different techniques should be made clear to any prospective mother.
‘It is very important that women who are freezing their own eggs for future use are properly counselled,’ she said.
‘There is no guarantee that we are going to have an embryo transfer, let alone a birth. It is extremely important that women have the proper information.’

But Dr Gillian Lockwood, medical director of Midland Fertility, pointed out that a woman who is 40 will be far more likely to have a successful birth if she uses eggs she had frozen at the age of 32.
She also pointed to the results of 2011 study conducted in Cyprus, which suggested that under careful treatment frozen eggs work just as well as fresh.

Professor Rebecca Sokol, president of the American Society for Reproductive Medicine, added: ‘There are a host of reasons that a patient may need to freeze her own eggs.
‘When faced with chemotherapy or other cytotoxic treatment, egg freezing is the best hope of preserving a woman’s fertility.
‘If sperm cannot be obtained at the time of a fresh IVF cycle, egg freezing can salvage the cycle.’
The data comes after IVF pioneer Robert Winston warned last year that egg freezing has been ‘grossly oversold’ – and most women who put motherhood on ice have very little chance of having a baby.
He said that the process is ‘grossly oversold by commercial interests with very little practical chance of a baby in most instances’.
Lord Winston added: ‘That’s not to say it shouldn’t be done, provided it’s safe. But I don’t think people who are having their eggs frozen realise just how low their chances of having a baby are.’
