>Prior to this work, the strongest evidence for a link between testosterone exposure and reduced cognitive empathy came in 2011 in a study that found administering testosterone to healthy women reduced their performance on a test of reading emotions. The results suggested the testosterone impaired their performance.
That's interesting. Adult males typically have 7-8 times the levels that females do, and females are more sensitive to it. I'd hypothesize that injecting females with extra testosterone was just plain mentally disorienting. I know a trans man who, after a few months of testosterone, claimed it was "night and day" in how they felt about and processed the world. Female biology isn't adapted to high levels of testosterone like a males biology is.
