Initial Quick Thoughts on the Announcement of the Birth Through Mitochondrial Replacement in Mexico

The science media is abuzz about the birth of a child using mitochondrial replacement techniques in Mexico to Jordanian parents at the hands of NY Doctors. A few quick reactions (I am heading to this unrelated NAS/IOM Committee meeting tomorrow evening so may have some more thoughts when that settles down).

  • This is the first time this particular technique has been used to produce a live, but I am not sure from an ethical standpoint the arguments are all that different. That said, for those deeply interested in the more philosophical question of harm to children and the propriety of best interests argument in light of Parfit’s Non-Identity Problem (my take here and here) it may matter whether mitochondrial replacement is done through Pronuclear Transfer or Maternal Spindle Transfer as argued quite well here.
  • The fact that the doctors are from New York, the Patients are from Jordan, and the procedure took place in Mexico is not insignificant. This is a form of medical tourism, a topic I wrote a book on, most similar to cases of fertility and stem cell therapy tourism I cover in the latter half of the book. Absent making domestic prohibitions extraterritorial, something that I argue is permitted by international law and justified in some instances, there is very little that a home country can do about this. The going abroad is likely in part at least a function of some U.S. laws on the subject Eli Adashi and I wrote about for JAMA prohibiting FDA from considering approval of the technology.
  • As I wrote on this blog in February in relation to the IOM report “whatever the US policy in a world where medical tourism is possible and other countries adopt their own systems, so long as not everyone adopts the approach of the US some of these problems will manifest no matter what. So this is about harm reduction not harm avoidance.” This was a bit quicker than even I thought, but is not surprising. More generally if your concern about MRT is harm to offspring and transmission to future generations, people born elsewhere through the technology will inevitably enter the United States and/or marry, and procreate with U.S. citizens who themselves become U.S. citizens. To sound a bit X-Files about it “THEY WILL BE AMONG US!” This is a great example of the limits of unilateral regulation in a world of globalized health care.
  • Interesting that it was a male birth. This may be coincidence or in keeping with the IOM recommendation that only male embryos be transferred (to get rid of germ line transmission). Eli Adashi and I raised some ethical questions in Nature about whether that was an ethically problematic form of sex selection or not but in the reporting I have seen so far it has not been clear that they used only male embryos on purpose.
  • I wish we could stop calling it in the media “Three Parent IVF” or “Three Parent Reproduction.” That assumes the answer to what I think of as a subtle and interesting set of questions — is the mitochondrial donor a “parent” and what sense of the word do we mean.

More soon, I hope!
