Sorry for replying late, didn’t see this message.
I sadly do not have the link to this study as I heard this info a while ago.
Though I came across a whole lot more studies saying that trans women athletes have higher testosterone levels. Makes sense if they experienced male puberty before and didn’t prevent it using puberty blockers (since the majority of testosterone is created during puberty). Assuming they DID use puberty blockers, they should not have a significant competitive advantage.
Outer Wilds is an amazing game to 100%, all “collectibles” are pertinent to the world and story of the game.
