Although testosterone is at higher levels in males, it is not a male specific hormone. Males have around ten times as much testosterone as females. The levels vary in both genders with similar effects seen at the relative levels within the gender specific ranges.

John Manning et al, has associated gender specific high levels of testosterone with autism. I have always believed at least some degree of autism is in part responsible for what is classified as gifted. Gifted in my opinion is an indication someone has strengths in the areas our current society sees as valuable. This does not necessarily mean everyone else is any less intelligent, they just have strengths in other areas or less obvious strengths.

I basically agree there may be a coorelation between gifted and prenatal testosterone levels. The coorelation in not linear however as extremely high levels of prenatal testosterone leads to severe disabilities.
