The current evidence is inconclusive, but many obvious alternatives have been ruled out.

Furthermore, if true, it shouldn't be overly surprising, since gametes are another stage in the life of an organism with great selection pressure. Why assume it behaves randomly?

Does this (read: could this) help explain why some couples have problems conceiving? Perhaps, at least in some cases, the egg is saying, "no way buddy."

I haven’t looked it up but I’d say there’s anectodal evidence of couples that conceived with different partners after having trouble conceiving between them.

Just met an airbnb host with the exact same story. Tried for years then broke up - both had kids right away with their new partners

It would make evolutionary sense to have the ability to select better sperm.
