Do read the whole thing. I think it is a little misleading as it seems to imply all ET involve a blast and as we know that is far from the case. Plus the research is still going on to find which are the marker genes, the team are a LONG way from a reliable test.Scientists have used gene analysis techniques to help identify the genetic profile of IVF embryos that result in a successful pregnancy.
The Australian researchers believe it could end the need to transfer more than one embryo into a woman's womb to maximise the chances of success.
If only viable embryos were selected, there would be no chance of potentially risky multiple pregnancies.
The study appears in the journal Human Reproduction.
