Chromosomal mosaicism, or the co-existence of cells with different chromosomal content, is a phenomenon that has been documented in human embryos for three decades. Early versions of preimplantation genetic testing (PGT-A) did not measure mosaicism, either because typically only a single cell was assessed, or because the technique could not accurately identify it. While this led to a straightforward diagnosis (an embryo was considered either normal or abnormal), it simply avoided the matter and in hindsight may have led to numerous misdiagnoses with negative clinical consequences. Modern PGT-A evaluates a multicellular biopsy with technologies capable of recognizing intermediate copy number signals for chromosomes or sub-chromosomal regions. We are therefore inevitably confronted with the issue of mosaicism and the challenge of managing embryos producing such results in the clinic. Here we discuss recent data showing that not only mosaicism in general, but specific features of mosaicism detected with PGT-A are associated with variable clinical outcomes. The conclusion is evident: mosaicism should be considered for more informed and improved embryo selection in the clinic. Features of mosaicism revealed during preimplantation genetic testing for aneuploidy are associated with variable probabilities of achieving ongoing pregnancy and should be considered when prioritizing embryos for transfer.
