Assuming this is true, it would be happening in less than 1% of cases (given the prevalence of male-factor infertility and the prevalence of its known causes). So if such an ability exists, it doesn't seem to be getting used very often. Which, given the evolutionary complexity that would be required to evolve such a system, seems surprising. So my guess is that either that's not a thing, or else it exists only as a failure state of some other mechanism rather than as something that has evolved to directly confer some sort of reproductive advantage.

- caio1982 9y agoJust incompatibility, without the partner. Fluids pH problems are much more common than you'd think, and it has nothing to do with the partner (besides being treatable). And it's just one of the many problems that may occur, but none of them is like a partner issue because your bodies don't "match".
- chiefalchemist 9y agoYes. But if the egg is making a decision can't other parts of the process, at least in theory, be serving as gate keepers as well? Thst is, it's not just the egg being selective. Selective is baked into the recieving organism (i.e., the human female). To me that doesn't sound too far fetched and to some extent makes perfect sense.
