Testosterone: Making a Man?

52' (GER, ENG subs)
Testosterone was long regarded as the bad guy among hormones. We review the myth of testosterone controlled men.

Testosterone stands for health, sexual desire, elixir of life and is regarded as a social behavioural hormone. The testosterone-controlled man is willing to take risks and is selfish with a tendency to aggressiveness. Characteristics that today have a rather bad image. But does the messenger substance really make you aggressive or does it even promote social behaviour? This is now suggested by the latest scientific studies.
Internationally renowned researchers explain how subtly the hormone actually works. The word "hormone-controlled" needs to be re-evaluated. Unlike in the animal world, the statement "testosterone makes aggressive" cannot be confirmed in humans.

One of the leading experts in this field is Jean-Claude Dreher from Lyon. In his laboratory experiments, he proves that testosterone does not make men aggressive, but allows them to act strategically. Those who carry more testosterone in their bodies treat others more friendly in order to strengthen their own status.

The British behavioural psychologist Simon Baron-Cohen has also investigated whether and to what extent the testosterone content in the womb already reveals different behavioural characteristics in boys and girls. Research has shown that hormone levels affect brain development and thus the development of empathy, speech and abstraction.
One thing is certain: the simple equation "testosterone equals aggression equals power" does not work.
