Oxford researchers are giving hope to would-be-parents with an embryo test that could increase future IVF pregnancy success rates from 30 to 100 per cent.
At the moment many cycles of IVF do not lead to pregnancy because of chromosomal abnormalities. These abnormalities can be picked up by the new checks.
Dr Dagan Wells, head of the research team at Oxford University said: 'In the future we will be able to compare embryos that make a baby and those that don’t.
'Once the test is developed it is likely to cost about £2000 on top of the cost of a round of IVF treatment.'
The team aims to guarantee pregnancy with the first round of IVF treatments, reducing the cost and stress for the parents.
Tony Rutherford of the British Fertility Society said: 'Selecting the right embryo for replacement in a cost-effective, reproducible manner potentially has enormous benefits for patients.'
The IVF test procedure is expected to begin trial cases in Oxford later this year with an aim to become more widely available across the UK by the end of 2012.
