3 person ivf

What’s that, you may ask. One sperm and one egg is all that’s needed to make an embryo, right?  Well, it appears not!!

You can remove  parts of someone else’s embryo (in this case the cytoplasm) to transfer into your embryo to correct chromosomal deficiencies and help deliver normal children. The nucleus remains the same, so the children still do carry your own genes (generally) and they would still be genetically yours.

It is not technically difficult to do, but the ethicists cant decide if this is a scientific advance, or a step in the wrong direction. If you are the parents of children who have suffered and died from a mitochondrial chromosomal defect, then you would definitely support this.

Me? I support any scientific advance in ivf which helps parents overcome fertility problems and have healthy children.
