Who wants to implant an embryo that has had a chunk taken out of it?
Based on how the article said it was done, not sure that ONE CELL could be classified as a CHUNK
If you were the person undergoing fertility treatment, you’d probably prefer to implant an embryo that had no procedure done to it for your pregnancy, even if the procedure only takes out one cell, because it means it’s been handled somehow, so there is more risk of a problem with the embryo. Even if the procedure was a lot cheaper if you opted for the “certified pre-owned” embryo, I think many would still want theirs to be absolutely pristine.
