Lords ChamberThe noble Baroness is absolutely right that it is important that we continue to support the Bill. I was trying to clarify that I did not think it appropriate to bring forward a change of this nature under regulations. If we were to introduce a change that had a broad effect, it would be appropriate to do so in primary legislation with appropriate parliamentary scrutiny, consultation and clinical support.
My Lords, if I may, in the absence of the noble Lord, Lord Winston, I will take his perch—as long as nobody tells him that. The question of the science has been referred to. As far as we know, 26 years is the longest that an embryo that was subsequently born managed to survive. However, nobody really knows—we know only of the ones that have been reported. As for how long an embryo might survive, a study that measured the cumulative index of background radiation in mice suggested that when the mice embryos were subjected to increasing levels of cumulative radiation, they survived up to the equivalent of 2,000 years. Therefore, a 10-year limit has no scientific basis. Does the Minister agree?
I would never argue with the noble Lord, Lord Patel, on any scientific matter. My information is that there was no scientific or biological basis for the 10-year limit. It was based on debate and discussion of societal, ethical and cultural considerations, and on the concern that without a maximum limit, there would be questions about storage banks. Vitrification techniques are far more effective now than the slow-freezing techniques, so it is appropriate that these scientific questions are taken into account as this remains under review in the department.
