For example,
United kingdom: eight babies born:
In vitro fertilization
In the United Kingdom. Therefore, babies were born thanks to the DNA of three people – United kingdom: eight babies born
For the first time, children were born with the DNA of three people. Furthermore, An advance that opens the way to the eradication of genetic diseases.
Thanks to a legalized IVF technique in 2015 in the United Kingdom. Similarly, involving the DNA of three people, babies were able to be born without inheriting the “risk” genetic material from their mother.

- British doctors celebrate the birth of eight babies from three DNA.
- The technique prevents genetic transmission of serious mitochondrial diseases.
- This technique is not possible in Switzerland given the current legal framework.
Three people for a single baby: history seems improbable. Similarly, but it represents an unprecedented advance in the fight against incurable genetic diseases. Moreover, In Newcastle. For example, in Great Britaina team of researchers allowed the birth of eight toddlers thanks to an in vitro fertilization technique combining the DNA of three people. Nevertheless, This procedure was authorized in the United Kingdom in 2015.
The fertilization technique implies: the mother, carrying “bad” mutations, the father, and a ova donor. However, It consists in fertilizing the mother’s egg with the father’s sperm. then transferring the nucleus formed in the healthy egg of a donor. The child thus inherits the genetic heritage of his two parents – while benefiting from the healthy mitochondria of the donor. which represents approximately 0.1 % of her total DNA.
A “three” IVF
Thanks to this “three” IVF. it becomes possible to block the transmission of maternal mitochondrial diseases, often fatal hereditary conditions. The mitochondria are in a way the “energy power plants” of our cells because they have their own DNA. As a result, if they are defective, they may cause severe disorders by affecting the brain, heart or muscles. About one in 5000 baby is affected.
The eight children born in the past six years, four boys and four girls, are all healthy. “After years of uncertainty. this treatment gave us hope, then he gave us our baby,” says one of the mothers at the BBC.
Possible in the United Kingdom. not in Switzerland
Before knowing if this medical feat is a success, children will have to be followed closely in the united kingdom: eight babies born coming years. But this scientific advance also raises important ethical questions. Modifying the DNA of baby to be born questions. certain voices fear that it is an open door to children with “tailor -made” genetic heritage.
For the moment, only certainty in this complex ethical context: this technique is not possible in Switzerland. The country has indeed adopted a conservative approach in medically assisted procreation. with restrictions which distinguish it from many European countries, including the prohibition of ova donation.
But the legislative framework is being evolved. Parliament accepted in 2022 A project aimed at legalizing ova donation, so far impossible in Switzerland, unlike sperm donations. The new text should be put in consultation by 2026.
