The method has started being used in genetic research and diagnostics, but not yet in embryo screening, according to Wells.
"Many of the embryos produced during infertility treatments have no chance of becoming a baby because they carry lethal genetic abnormalities," he said in a statement. "Next generation sequencing improves our ability to detect these abnormalities and helps us identify the embryos with the best chances of producing a viable pregnancy."
Current methods of detecting embryonic gene deficiencies add over £2,000 (2,300 euros, $3,000) to a single IVF attempt, said Wells.
"The new method should allow costs to be reduced by several hundred pounds, potentially bringing the benefits of chromosome screening within the reach of a far greater number of patients," he told AFP.
Wells had tested the method on "abnormal" embryos in the laboratory until he was satisfied of a high level of accuracy, then used it to help two couples undergoing IVF. The mothers were aged 35 and 39, and one had previously had a miscarriage. Wells said the method identified three healthy blastocysts (early embryos) in one couple and two in the other.
