The first babies to be created using a “three-parent” method to overcome their parents’ infertility are due to be born in early 2017…[T]wo women in Ukraine are both more than 20 weeks pregnant with fetuses created using such a technique.
The babies would be the first born to women who had the procedure to treat infertility, rather than to prevent hereditary disease, but some have criticized this approach, calling for it to be banned until there is more evidence that the embryos it creates are healthy.
A key argument [for this technique] considered in the UK parliament [in 2015] was that, for women with serious mutations in their mitochondria, there are no other possible treatments. But there are already many options for treating infertility, meaning some may be less happy to see it used for this purpose.
“There is much debate, and indeed, much pressure from the fertility world to get this treatment accepted,” says Bert Smeets at Maastricht University in the Netherlands. “It’s obvious that the fertility market is much bigger than the group of patients with mitochondrial disease.”
