How does this compare with natural conception? Doesn't a fair proportion
of naturally conceived fetuses simply never lodge in the uterus or
miscarry rather early in the pregnancy?

This is one more example, though, of the precautionary principle being
applied. You can't get the safety margin down without experimenting, so
saying you can't experiment until you get the safety margin down is
simply imposing a ban by illogic.
