And why not? The propensity to take risk seems to be quite a low-level drive, and we definitely see strong hints that hormones can have a measurable influence[1] on risk tolerance in both men and women. If you look past ourselves in the animal kingdom, males are far more likely to engage and risky and aggressive behaviors because males that don't take large risks by and large won't manage to reproduce.
