I'd remind you that in these experiments so far, about one quarter of the lambs that were born alive died within a few days because they hadn't completed normal development. Now, what may be being suggested here is that copies of children would be being produced, and some of those would die soon after birth. So I think that for a clinician to be suggesting doing that is a quite appalling and sad thing for him to be suggesting.
