Mosaic embryos, which are characterized by the
presence of a mixture of diploid and aneuploid cell lines,
are not usually transferred because they are deemed to
Although the effect of mosaicism on implantation and the
developmental potential of these embryos is not
known, it is reasonable to assume that mosaicism
reduces the likelihood of success of IVF.
Our study shows that mosaic embryos can develop into
healthy euploid newborns. Thesefindings have implications
for women who undergo IVF resulting in mosaic embryos
but no euploid embryos.
