Philosopher Tina Rulli argues that three-person IVF is not a “life-saving therapy” or even a medical treatment at all. Rulli explains why the technology does not meet a plausible social value standard that would justify public research investment, and why other germline modification techniques may not either.
If you have seen any of the countless descriptions of three-parent or three-person IVF, also called mitochondrial replacement, as a “life-saving treatment,” you might find the question in the title confusing. How could any life-saving treatment not be of value?
As Rulli explains, the claim that this technology would save lives is “inaccurate and exaggerated.” Three-person IVF would not cure, treat, or save anyone. At best, it would allow women affected by a particular kind of mitochondrial disease to have an unaffected child who is mostly genetically related to her.
The experimental procedure works by genetically engineering an embryo to combine the intending mother’s nuclear DNA with another woman’s mitochondrial DNA. The choice a woman would make is not “do I save my child?” but “do I want to have a child in this way?” Rulli makes a strong argument that these are not morally equivalent, and that it is irresponsible to act as though they are.
How one thinks about this distinction between creating an unaffected genetically related child and saving lives may have implications well beyond three-person IVF.
