New test could ‘virtually guarantee’ IVF success
Summary of story from The Daily Mail, October 18, 2011
A new 3-in-1 test, introduced at the American Society for Reproductive Medicine’s annual conference, aims to cut the financial and emotional costs of trying time after time to start a family.
IVF costs between £3,000 and £15,000 a course, but success is far from guaranteed. Just one in four of the 40,000 women who have it each year have a baby.
Dr Dagan Wells, of Oxford University in the UK, developed a technique two years ago that allows only the best eggs or embryos to be selected for IVF.
This test is known as array comparative genomic hybridisation (CGH) which counts the number of chromosomes in an egg or embryo.
He now hopes to add on two additional checks that could take the IVF success rate from the 80 per cent or so of array CGH to approaching 100 per cent.
The British Fertility Society has previously cautioned against the use of array CGH until there is large-scale data on how well it works.
