IVF clinics usually report their “success rates” in terms of births or pregnancies per 100 reproductive cycles. They boost their reported rates, and obscure the high death rate of embryos, by transferring two or more embryos per cycle to attempt one live birth. Deliberate destruction of unborn human beings may also occur before any attempt to transfer embryos to the womb (discarding embryos that do not appear to be of the highest “quality”), and after implantation in the womb through “selective reduction” (targeted abortion) if more embryos survive and develop than were wanted.
