男性（n = 42）和女性（n = 42）的性二态认知表现与睾酮、雌二醇有关。孕酮、黄体生成素、卵泡刺激素和性激素结合球蛋白，在0900和1030之间采集10毫升血液样本，在女性中，在月经周期的卵泡期进行测量。显着的性别差异有利于男性的空间任务（心理旋转和判断线方向）和抑制任务，有利于女性的口头任务（类别流畅性）。然而，没有任何激素和认知能力之间的显着关系，这表明有几个，如果有的话，一致的，实质性的关系之间的内源性，非波动水平的性腺激素或促性腺激素和这些认知能力的男性或女性。
Sexually dimorphic cognitive performance in men (n = 42) and women (n = 42) was related to testosterone, estradiol. progesterone, luteinizing hormone, follicle-stimulating hormone, and sex hormone binding globulin, measured in 10-ml blood samples collected between 0900 and 1030 and, among women, during the follicular phase of the menstrual cycle. Significant sex differences favored men on spatial tasks (Mental Rotation and Judgment of Line Orientation) and on an inhibition task and favored women on a verbal task (category fluency). However, there were no significant relationships between any of the hormones and cognitive performance, suggesting that there are few, if any, consistent, substantial relationships between endogenous, nonfluctuating levels of gonadal hormones or gonadotropins and these cognitive abilities in men or women.
