Reply to comment by Budget_Bathroom_1056 in TIL When a cow has opposite sex twins, the female twin is usually born intersex and infertile. This happens because the twins blood supplies are linked, which exposes the female to male sex hormones. by awawe

Apparently it does affect the twin somewhat but nowhere near the amount it affects most other mammals. It might be because we take so long to develop and that sex differences aren't so huge at a younger age for humans? That's just a guess from me though.

Cows and humans gestate for the same length of time, oddly enough. But they do mature a lot faster...

I just read the article you linked, but it says there’s no difference. “SUMMARY Women with a male co-twin had the same chances of being pregnant and having children compared to same-sex twin pairs.”

The key here is that we need to understand that humans have hormonal influences on their offspring during pregnancy, these influences can result in gender disparities that may make a child feel as though they are misgendered. I wish that people could understand that a person born of one “sex” may never be able to adapt to being that person.

Do you have a source for “pregnancy hormones cause gender disparity”? I don’t know if that’s true and I’d love to read about it
