The results of a study in the Journal of Behavior Medicine show that the average testosterone level in a male is between 400 and 600 nanograms per decilitre of blood. The average level in a female is about one-fortieth of that. Having high testosterone, in both males and females, influences your behaviour and fertility and yields a variety of problems and benefits.
The production of testosterone is influenced by your genetics as well as the food you eat. Soy and alcohol will decrease testosterone levels, while fat and animal products will increase them.
One of the main symptoms of high testosterone in women is the growth of masculine hair on the face and on the chest. This is called hirsutism. The hair can grow in great abundance, and be damaging to a woman's self-esteem.
Women whose testosterone levels are too high also have increased fertility problems. They have great difficulty getting pregnant and they give birth to smaller babies.
While it a burden for women, being a man with high testosterone has a number of advantages. Men with high testosterone have increased sex drive, better heart health, are more fertile and more energy than men with lower levels of testosterone.
Too much testosterone, even in men, is a bad thing. Men with extremely high testosterone levels are more prone to aggressive and self-destructive behaviours. Such behaviours include reckless driving, alcohol abuse and violent crimes.
