The international team led by Dr Dagan Wells of Oxford University showed how "next-generation sequencing" can be used to pick the embryos created by IVF that are most likely to lead to successful pregnancies.
The approach can identify embryos with the correct number of chromosomes and may cut hundreds of pounds off the cost of embryo screening, Wells said.
The majority of embryos produced by IVF aren't able to lead to successful pregnancies, and scientists have sought to find ways of identifying the embryos that should be implanted to give the greatest chance of success.
Having an incorrect number of chromosomes usually prevents embryos from producing a pregnancy. Until recently, such abnormalities have been hard to detect as they do not affect the appearance of embryos under the microscope.
"Many of the embryos produced during infertility treatments have no chance of becoming a baby because they carry lethal genetic abnormalities," Wells, said. "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. Potentially, this should lead to improved IVF success rates and a lower risk of miscarriage," he said.

I believe in life at birth and not at conception, and quality of life is more important than preservation of life. Still sometimes I am conflicted by the advances in science.
