This also massively effects the risk/reward balance. Ultimately, a woman’s ability to have children is limited by her biology. The limit on men is FAR higher.

For women, once they hit the resource requirements to support 2 dozen children, there was relatively little real gain. A successful man could (in theory) have hundreds of children. Genghis khan being the most egregious example. Taking large risks for large gains makes sense for men, in a way that just doesn’t for women.
