Over the last decade, scientific advancements have been absolutely vital for improving the quality of life for millions of people. Now, that’s been taken a step further, and the impressive work of doctors in Newcastle could benefit generations to come. In a move to prevent children from being born with deadly genetic diseases, an advanced form of IVF has been created that would result in a baby being born from three parents – two mothers, and a father.

As incurable mitochondrial diseases are only passed down from the mother, this new technique will involve using a donor’s egg as well as that of the mother, and the father’s sperm.

Approved by the UK’s fertility regulator, this is an advancement that is sure to have success. According to Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority, “It is a decision of historic importance.”

“This is about cautious go ahead, not gung-ho go ahead, and there is a long way to go. I’m sure patients will be really pleased by what we’ve decided today.”

However, this decision has not been without criticism.

Some people fear that this may cause genetically-modified babies to be deemed as acceptable, but it has been emphasised that this process will only be used in cases where the risk of developing the disease is very high.

So, how does it work? 

The disease is caused by defective mitochondria, which are present in almost every cell. So, by using healthy mitochondria from the donor, the aim is to avoid passing on the disease, but while ensuring that DNA is still passed on from both parents.

What do you think? Clearly, this could benefit a huge number of people, but is it ethical? Let us know below.
