The relationship between serum total testosterone (T) level and the fluid intelligence (Cattell's Culture Fair Intelligence Test) was studied in men and women. There was no significant difference between IQs of men and women. There was an inverse curvelinear relationship between IQ and T in women. The same was found also in men, but the declining part of the regression line at high T levels was not as pronounced as in women. It is concluded that T may be related to IQ, even in subjects exhibiting no sex difference in IQ tests; too low or too high T levels may be disadvantages for the fluid intelligence, especially in women.
研究了男性和女性血清总睾酮（T）水平与流体智力（卡特尔文化公平智力测验）之间的关系。男性和女性的智商没有显著差异。女性的智商与T呈反向曲线关系。男性中也发现了同样的情况，但在高T水平时回归线下降部分不如女性明显。得出的结论是，即使在智商测试中没有性别差异的受试者中，T也可能与智商有关；过低或过高的T水平可能对流体智力不利，尤其是在女性中。
