I’m a grad student in evolutionary biology. This does happen in a lot of animals (a few vertebrates and a lot of invertebrates) but I’ve never seen a study that says it happens in humans or anything closely related to us.

Yes, so many amazing adaptations in reproductive biology and these sasquatches decide they can apply every single one to human women 🙄

I love the zebras which can just eject sperm they don't like even before the unfortunate male has dismounted - like I applaud your effort sir but you will not be making it to the next round 😅

I'm an amateur student of zoology, so I know of animals that can induce miscarriage when conditions are bad, or put pregnancies on hold. I know of animals who can store sperm, choose sperm, etc. But specifically, inducing a miscarriage when she finds a "better" mate? Do you have some examples of the species who do that?

Does it happen in any mammalian species? Or is this like a weird fish thing?
