The relationship between testosterone and route-learning strategies in humans

The relationships between route-learning strategies and circulating testosterone and estradiol levels were investigated in men and women. Testosterone and estradiol concentrations were measured by salivary assays and route-learning strategies were assessed using a direction-giving paradigm based on a novel map. Testosterone was positively correlated with the use of male-biased route-learning strategies in men, but not in women. These findings suggest sex-specific patterns of relationships between circulating testosterone and spatial processing, which apply to everyday spatial behavior.
