Amsterdam, May 17, 2013 - Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced the publication of a recent study in Reproductive BioMedicine Online on 5-day old human blastocysts showing that those with an abnormal chromosomal composition can be identified by the rate at which they have developed to blastocysts, thereby classifying the risk of genetic abnormality without a biopsy. In a new study the same group has undertaken a retrospective study, using their predictive model to assess the likelihood of any embryo transferred resulting in a successful pregnancy, with very encouraging outcomes.
One of the greatest challenges in assisted reproduction is to find the one embryo, which can develop successfully. Now, combining time lapse imaging of IVF embryos cultured for 5 days to the blastocyst stage with trophoblast biopsy, it has proved possible to correlate the rate of blastocyst formation with chromosomal abnormalities. Such an approach should allow early and widely accessible non-invasive identification of the best embryo to place in the uterus.
"Recently the world of IVF has become very excited by the use of time-lapse imaging (TLI) of early human embryo development to follow the change of embryo morphology over time", explains Martin Johnson, Editor of Reproductive BioMedicine Online. "The data can then be compared with the outcome after the embryos are transferred. The hope is that this morphokinetic analysis will enable reproductive specialists to predict more successfully those embryos most likely to generate pregnancies. The advantage of using morphokinetic analysis to predict outcome is its minimal invasiveness."
The majority of embryos that fail to initiate a pregnancy do so because they have abnormal chromosomes. Unfortunately these embryos cannot be recognized by embryologists using c
