There are many adults that want to do all sorts of horrific destructive things to their bodies. Not all should be allowed, but of course where that line is drawn is very culturally dependent.

I'm mainly worried about the increased risk of infant mortality and deformity form experimental forms of reproduction like that.
Any new form will cause increased risk. That's simply unavoidable even with near utopian levels of medicine like pre-game-setting THS.

It's easiest, for me at least, to assume some past Mengele that had way to much time and funding did the horrific heavy lifting. Now everyone just coasts on "his" work like much of modern western society with regards to our horrific "animal" and human experimentation.
It's easy to omit Nazi experimental data mainly, because nearly everything they did was not just inhumane but also incompetent science.
