Mounting behavior of female wild-type (WT), heterozygous (HET), and aromatase knockout (ArKO) mice. All females were ovariectomized in adulthood and tested once for mounting behavior with an estrous female when treated with testosterone and then once more when treated with both testosterone and estradiol (5 μg/mouse/day). *p < 0.05 compared to WT and HET females, #p < 0.05 compared to WT females. Data shown are means ± SEM.
