There are suggestive data to link salivary testosterone concentrations (ST) to cognitive abilities in humans. Saliva reflects the plasma-free fraction of ST, which is biologically active, available for uptake by tissues including the brain. In the present study, therefore, salivary testosterone levels in healthy preadolescent children of both sexes, 6 to 9 years old, were determined. Among a total of 215 participants, 122 were intellectually gifted, attending special classes for gifted in primary school (IQ 130 or more in two independent standard tests of general intelligence). Their ST levels were compared with ST levels of 93 non-gifted children attending regular primary school. In general, results show there are no changes in ST concentrations between ages 6 and 9. However, there are significant differences between gifted and non-gifted participants. ST levels in gifted children were lower (p < 0.01) in all age categories. This also holds for both sexes separately (p < 0.01). |
