Newcastle University researchers have reported eight healthy babies born in the UK through mitochondrial donation and pronuclear transfer technology, aimed at preventing maternally inherited mitochondrial DNA diseases. The IVF technique involves transplanting the nuclear DNA from a fertilized egg of an affected woman into a donor egg with healthy mitochondria. These births are documented in recent New England Journal of Medicine publications and mark a significant milestone in reproductive medicine, offering hope to families at risk of mitochondrial disorders.
