Thats still a magic line drawn between nowhere. Science is just better understanding of the natural order. Technically a woman could have octuplets without IFV (at a rate of 1:80N-1 , N being the number in the "litter" so about 1 in 20 trillion) and without the knowledge (science) of female fertility one could sleep with a woman with zero chance of impregnating her (wrong time).
And some mammals raised in isolation from their kind, don't learn how to mate properly at all.
There is no magic line between science and nature. Science is nature, it is merely the better understanding of the natural world.
Drawing an arbitrary line and saying "thats natural" and "thats unnatural" is just an appeal to emotion rather than logic.
