Dopamine is associated with motivation and pursuit behaviors and operates closely with the testosterone system.

“Dopamine, as I mentioned earlier, has a number of effects in the brain and body. But one of the primary effects is that it places us into states of motivation and pursuit for various things. There is somewhat close relationship between the dopamine system and the testosterone system in the hypothalamus, this brain area above the roof of your mouth. And the pituitary gland, which is responsible for making hormones that make the ovaries and or testes, secrete testosterone or estrogen.”
