I searched pubmed and I’m pretty sure this is anecdotal, unfortunately. Hard to say how much of the volume of non-straight/trans and trans/trans twins on social media is selection bias since the trans/cishet twins aren’t eye-catching. There seem to be a lot but gosh do folks love to hear about twin similarities. It’s worth noting most are fraternal but that’s consistent with the general population.
I understand where Kamirose is coming from, but it’s not empirical (unless there’s a study that used some really weird terminology and I missed it).
Edit: I found a review and its citations do not converge well due to small sample sizes (hard with trans + twins - two rare things for births).

It’s not just selection bias, it’s also survivor bias. Openly trans people are more likely to have openly trans siblings, because openly trans people are more likely to have accepting parents. We don’t know what the actual frequency of trans people is. We only know what the frequency of out trans people is. But the number keeps going up the more acceptance improves.
Thanks for the extra legwork! These are cited by the review. I’m hopeful that there will be more research and data available on gender dysphoria as time goes on with more people being able to seek gender affirming care. 🤞 the horrific backlash doesn’t scare too many into staying in the closet or stymie funds/grants to these efforts.

I did a websearch for
