>>49631127>Among right-handers, salivary T was found to be negatively correlated with spatial performance in males, but was positively correlated with a measure of spatial visualization in females. This pattern was not evident in left-handers. This study doesn't even say it's a gender thing, just that testosterone seems to help women with spatial tasks but not men (and apparently none of this applies at all if you're left handed). I wouldn't draw any solid conclusions from this.
