But it reads to me like the thread parent's point is that there are many unknown risks which can exist? I also wonder about long term effects to the health of the genome from IVF and other forms of fertility treatment as infertility could be acting as some sort of protection mechanism of the genome. But I suppose such objections form a continuum which extends to treatment of all genetic diseases or diseases in general--all of which probably applies some evolutionary pressure towards more healthy individuals but which we as a society have to balance against wellbeing of individuals and their human rights.

This seems distantly impossible right now, but for this reason, I predict that any species that survives this kind of "great filter" effect of accidentally messing up their genome long term, will develop a strong taboo against fertility treatments and treatment of genetic diseases.

Like it seems horrible not to help the individual, when we have the technology to; but it's also horrible to hurt your species by selfishly propagating faulty genes. And this seems like the kind of problem cultural taboos are good at solving, and I don't really see any other mechanism by which a species can avoid this filter trap.

There is precedent for infertility being beneficial for a species in the animal kingdom. For example the vast majority of ants and bees are infertile. Yet the infertile ones still contribute meaningfully to society.

Humans could easily be successful with a similar model, and did so in the past before fertility treatments.
