Yes, the process can compromise the viability of the embryo, since losing some cells can be too stressful for it to survive. Even so, the survival rate is very high, especially when the PGD is done in blastocysts, since these embryos have a greater number of cells than those on day 3 and, therefore, are able to recover more easily after the biopsy.
Can extracting one or more cells from the embryo negatively affect its further development?
