The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.

I had labs done over 6 months ago. I am 53. My blood levels of Estrogens, Progesterone DHEA and Testosterone were way below normal for a women of 53. I am 10 years Menopause. My skin had become so dry and wrinkled in a year. Had severe vaginal atrophy. Medical Drs could not offer me anything but prescription patch which I refused.
I started taking DHEA 10 mg and 20 mg Progesterone Cream once a day. I started putting on weight. 8 lbs in two months... Which one is causing the Weight gain? Do I really need DHEA pill?
Also, neither one of them helped with the atrophy so I started using 1 mg of Estriol Oil Vaginally and what a HUGE
difference. and a Natural low dose of Testosterone. just within the last few weeks.
I will be having Saliva Tests in a few weeks. I think
the DHEA and Progesterone are causing the problem. Should I increase the Progesterone and drop the DHEA?
