According to the BBC, for the first time in the U.K., a baby has been born with DNA from not only mom and dad, but also another woman.  About 0.1% of the baby’s DNA came from the third party, through a mitochondrial donation. The idea of the procedure is to produce a baby without any of the diseases that result from unhealthy mitochondria inherited from the parents. 

Though hailed as “the only option for (parents with defective mitochondria) to have a healthy child of their own,” it’s not certain the procedure will work, nor whether a child born from the process will develop problems later in life. More troubling is that children are treated as a product that is owed to anyone who wants them, through an experiment conducted without a child’s knowledge or consent. 

And, no matter how noble the motives are, once this method enters medical toolkits, it will be used in other ways just like other medical procedures have been. As “throuples” and other relationships are increasingly recognized legally, this technology will be applied for different purposes, sooner not later.
