Description: Testosterone has been proposed as a mediating neuroendocrinology mechanism underpinning functional allocations of energy towards mating effort and away from parenting effort. However, work in humans has thus far been limited to correlational approaches. Here, we propose to test the causal role of testosterone on mate seeking behaviors--measured both behaviorally and using questionnaires--among men by administering a single dose testosterone using placebo-control experimental design. Further, we aim to test whether the effects of testosterone on mate seeking behavior differ as a function of men's relationship status.
