A baby was delivered in the US in May by using a new method that helps screen the embryos during IVF, according to researchers.
Connor Levy was born after the test - devised at Oxford University - helped the doctors pick an embryo with the best chance of success, an English news website reported.
The beneficiaries of the new treatment, Marybeth Scheidts, 36, and her hubby David Levy, 41, had been trying to conceive naturally for the past four years; they had also tried artificial insemination.
In the screening the doctors found that 3 of the 13 embryos produced were health, however, without the screening process, picking the right embryo would have been just down to luck.
Experts said that now larger trials are required to find out how efficient this new method is.
The new technique benefits from the advances in human genome sequencing and within a day can ensure the exact number of chromosomes present.
