Three Person IVF controversial fertility treatment: estimate about how many couples could benefit

A modelling study estimated the three-person IVF technique, currently illegal, could be used for thousands of women with genes linked to serious mitochondrial DNA diseases.

There was an initial debate on mitochondrial donation in the House of Commons on the 1st of September 2014. The Muscular Dystrophy Campaign, Newcastle University, The Lily Foundation and Wellcome Trust are organising a drop-in MP briefing session on Tuesday 3rd February from 12.30pm to 2pm in Committee Room 10.

The three-person IVF is designed to prevent babies being born with mitochondrial conditions by usinge healthy mitochondria from a donor egg to replace the mitochondria in the mother’s egg, either before fertilisation or just after, to prevent passing on mutations.

The study estimated almost 2,500 women of child-bearing age in the UK, and almost 12,500 women in the US could benefit from the new IVF technique. As this technique is untried, it is currently unknown how effective it may be, or what the short- or long-term consequences are.
