The accumulation of embryos from IVF, as practised in some countries, leads to an accumulation of large numbers of frozen embryos and eventually to their deaths. Countries like Germany and Italy only fertilise what they will implant in the womb. This respects human life. Professor John Bonner and Professor Martin Clynes have stated publicly that IVF can be carried out without loss of life and it is the irresponsibility of some IVF clinics that led to these "surpluses" in the first place. However, all that is a different problem from what we are now addressing.
