We have a PGT-tested monosomy 19 blastocyst that is presently frozen. Mosaicism was not detected. We are no longer doing retrievals. The lab that conducted our PGT-A testing said Monosomy19 is in the group of genetically abnormal embryos that is safest to transfer because it will lead to early miscarriage or no implantation and will not lead to birth under any circumstance. Do you share the opinion that as a last resort transferring this embryo is a viable option with minimal risk?
