The UK has now become the first country to approve laws to allow the creation of babies from three people.
According to a BBC report, the modified version of IVF has passed its final legislative obstacle after being approved by the House of Lords.
The fertility regulator will now decide how to license the procedure to prevent babies inheriting deadly genetic diseases.
The first baby could be born as early as 2016.
A large majority of MPs in the House of Commons approved “three-person babies” earlier this month.
The House of Lords tonight rejected an attempt to block the plan by a majority of 232.
