The findings, published in the journal Nature Communications, have the potential to vastly improve the success rate of single-egg IVF, which consequently could improve the prognosis for both mothers and babies, researchers say.
Current IVF embryo screening is a relatively qualitative procedure. Scientists fertilize an egg with sperm, and five or six days later, once the embryo has reached the 60-100-cell blastocyst stage, scientists evaluate the embryos’ morphology and the rate at which cells have been dividing. The best-looking embryos that have been dividing at the “best” rate are then selected for transfer.
Plucking a few cells from the blastocyst for genetic testing can increase the odds of choosing a successful embryo, but this invasive procedure can stress the embryo, even though the sample is taken from cells that will eventually form the placenta..."
