As explained above, we put the embryo at risk of being seriously damaged after the biopsy to the point that the embryo transfer has to be cancelled, even though it was a healthy embryo. Also, the result of the genetic screening might show that all embryos are genetically altered, in which case the transfer would be cancelled as well, and a new IVF-ICSI cycle restarted. Moving to donor eggs and/or sperm is another feasible option.
