In September the world learned of a US fertility doctor who had gone to Mexico where “there are no rules” in order to arrange the birth of a child conceived using 3-person in vitro fertilization (IVF), technically a form of human germline modification, to prevent mitochondrial disease. In October we learned that 3-person IVF is being used experimentally in the Ukraine to treat infertility.
In November we saw four additional important developments:
1) The media got 3-person IVF all wrong
On November 1, Reproductive Biomedicine Online published “Setting the Record Straight,” the journal’s editorial response to the “shoddy scientific journalism” surrounding an article in the very same issue. The article in question was a report on the apparent health of children born in the late 1990s and early 2000s using cytoplasmic transfer, a 3-person IVF precursor (see here for CGS’s take on the media coverage of that article). Published in the immediate aftermath of the Mexico and Ukraine cases, most media reports took it as evidence that current 3-person IVF techniques (pronuclear and spindle transfer) are safe. Railing against this misinterpretation, the editor argues that:
the technique of cytoplasmic transfer in the late 1990s is so different from those of pronuclear or spindle transfer as to make the apparent normality of the offspring born through the former technique of little relevance in the context of (the latter).
In other words, the media got it all wrong—the study doesn’t prove anything about the current or future safety of experimental 3-person IVF techniques.
