What's Estradiol doing?
Control Impulses? Lack thereof?
Estradiol is lower in men than women but vital for both sexes. Low estradiol levels may lead to
increased abdominal fat deposition, so elevated estradiol may not necessarily mean 'more feminine'.
Some studies say violent impulses may be an effect of the "warrior gene", which refers to a variant of the monoamine oxidase gene linked to aggressive behavior:

The Warrior Gene was found to be more or less prevalent in different ethnic groups [6].
The 3R version, which produces less MAO-A, was found in 59% of Black men, 56% of Maori men (an aboriginal New Zealand group), 54% of Chinese men and 34% of Caucasian men.
The 2R version, which produces the least MAO-A, is found in 5.5% of Black men, 0.1% of Caucasian men, and 0.00067% of Asian men."
