Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015

I wonder whether I can help my noble friend Lord Patel. Does he agree with me that there were very few available data for the first in vitro fertilisation babies, and that that was a step in the dark, as were pre-implantation diagnosis and sperm microinjection? Before he concludes his speech, would my noble friend be kind enough to answer an important question asked by the noble Lord, Lord Deben, about the possibility that we might be making infertile children? Was that not the accusation made when infertility was treated by in vitro fertilisation, and was there not a widespread fear at that time, too, that we would be making infertile children?
