Mitochondrial transfer and the HFEA
The CMA submitted its response to the HFEA consultation mitochondrial transfer and is saddened to see that the technology is to be allowed despite our concerns. Some will wonder why health care workers would oppose treating illnesses such as mitochondrial disease. The answer is remarkably simple.
We said in our submission that “Because we see the value in every human life and the mitochondrial transfer procedure involves the sacrifice of one life for another the Catholic Medical Association (UK) is completely opposed to this destruction of life. In other consultations we have made it clear that we do not agree with Embryo Research, as an embryo is already the beginning of a new, unique, Human Being. While we understand that Mitochondrial Diseases can be very serious and distressing, and it must be “good” to find a way of avoiding them, such a good “end” cannot be used to justify the “means” by which it is executed. In the situation of Pro Nuclear Transfer, where an embryo is destroyed, we do not believe this means can ever be justified.”
In the situation of Maternal Spindle Transfer, where two unfertilised eggs are involved, a human life is not destroyed, but we continue to oppose this because of the interference with the reproductive process and also the reality that implanted embryos have three parents, and there is permanent change on the gene line.
With both of these techniques we also know that, just as with IVF, the very large majority of embryos created will not survive to birth, with many failing to implant in the womb, and many more destroyed after storage.
As in other branches of medicine, and in all walks of life generally, we must oppose things that are wrong, even if they can bring some benefits. In the end, the ends cannot justify the means. And, in her opposition, the Church upholds to the highest degree, the dignity of every human person.
