New test could improve IVF success for women
Scientists have developed a new test that could help women who undergo IVF to have an 80% chance of a successful pregnancy. The test focuses on the behaviour of mitochondria in an embryo, as too much mitochondrial DNA in an embryo will mean a baby will never develop. The new findings come from the University of Oxford and the work has been shortlisted for two prizes, as the test could prove to be highly beneficial for couples who may have to struggle through fertility treatment.
In the UK around one third of IVF treatments are successful, and although the figure is rising by 1% every year, Professor Dagan Wells from Oxford University says that the improvement is still extremely slow. For example, if a woman produces eight embryos only one of the embryos may result in a successful pregnancy. However the new test could boost IVF success rate dramatically in the UK, and could be available in this country from next year. A clinical trial conducted in New York found that the test boosted the rate of a successful pregnancy by 80%.
