There was a really nice video that supports your point on youtube back in 2013. A lady scientist was doing a talk in a small european country about gender in rats. She found she could get male rats to 'present' and female rats to mount if she messed with 3 distinct moments of hormonal gender influence. One in the womb, one as a young child and one point at puberty. She went on to describe how male rats prefer risky behaviour because they beeline for cheese in the middle of a pool of water on an island and how female rats are more risk averse and swim around the outside edge first. I have found it impossible to find that video anymore. I don't know why we have to rely on questionable studies when there has been much better work been done and now black-holed.
