Chromosomal Mosaicism in PGT

ESHRE survey results and good practice recommendations on managing chromosomal mosaicism

The use of comprehensive chromosome screening technologies has provided a variety of data on the incidence of chromosomal mosaicism at the preimplantation stage of development. Even if evidence is accumulating, many questions remain on how to manage of “putative mosaic” embryos.

The ESHRE chromosomal mosaicism working group formulated recommendations based on a information on current practice, published data and expert opinion. These recommendations can be used by ART/PGT centres as a basis for their own policy with regards to the management of “mosaic” embryos.
