“Dangerous”, my noble friend says. It killed the other two and resulted in a premature birth. They never published this, despite being asked if there was a publication. It is wrong to say that the HFE did not ask them; the review panel did. Professor Grifo sent a letter saying that, in his view, all the foetuses were normal but they died of prematurity. What they died of was an obstetric botch-up. It had nothing to do with what we are talking about today. It was a completely different technique. We should dismiss it completely. It would be wrong to put any credence on it and say that it is a good reason why we should not do this.
I could go on about other safety aspects that were brought up, but let me close by saying that hitherto the science has gone as far as it can in thousands of animal experiments that have resulted in normal pups. In human embryos it has gone as far as it can to produce normal embryos, which, if implanted, there is no reason to believe would not develop into normal, healthy babies who would not carry the defective mitochondria. All we are doing today is allowing the regulator henceforth to decide, on a case-by-case basis, to issue a licence to those clinics for those mothers who request this treatment, and which are allowed to use both techniques that we currently know are safe while further research goes on. None of us stops researching: the noble Lord, Lord Winston, still carries on researching; the noble Lord, Lord Kakkar, still carries on researching. If a chance was given, the noble Lord, Lord Walton, would still carry on researching. We do not stop researching; that is the nature of medicine and of academic medical science. I hope that we will pass these regulations.
