A team from Monash University in Australia has developed a way to identify, and do a DNA analysis of embryos, which should improve the success of IVF procedures in the future.
Dr. Gayle Jones, co-author of the study, and a senior research scientists at the Monash Immunology and Stem Cell Laboratories said the following:
“One of the major stumbling blocks to worldwide acceptance of a single embryo transfer policy is the lack of highly predictive criteria to select the single most viable embryo within a cohort. The ability to use objective, measurable criteria rather than subjective observations, such as morphology, should improve the predictive value and provide sufficient confidence for clinicians to shift towards single embryo transfers for all patients without a concomitant drop in pregnancy rates. This would effectively reduce multiple pregnancies, which is a priority in the field of assisted reproductive medicine at present.”
