High testosterone doesn’t really make men more successful, new research tips

There is a widespread belief that your testosterone can affect where you end up in your life. There is some evidence of this claim, at least for men. Some studies have linked higher testosterone to socio-economic success.But the link is different from the cause and is using our new DNA research It suggests that it may not be much more important to life opportunities than previously claimed.

In a previous study, men board member Found to have more subordinates with higher testosterone, and found that financial traders with higher testosterone produce more daily Profit..Testosterone is known to be higher in higher Educated Men, and self employed It suggests a connection with men and entrepreneurship.

Little is known about these relationships in women, but one study found that women were at a disadvantage to their socio-economic position. childhood It was linked to higher testosterone later in life.

The beneficial effects of testosterone are thought to work by influencing behavior: experiments suggest that testosterone can make more people. Aggressive more Risk tolerance, And these traits can be rewarded in the labor market, for example in wage negotiations.

However, with other plausible explanations, none of these studies clearly show that testosterone affects these results.

Rather than testosterone affecting a person’s socio-economic position, having a more favorable socio-economic position can increase testosterone. In both cases, there is a link between testosterone and social factors such as income, education, and social class.

This also has a plausible mechanism.First, we know that socio-economic disadvantages are stressful and chronic stress can be stressful. Low testosterone..Second, how one perceives one’s status relative to others in society can affect testosterone: usually in studies of sports matches between men, testosterone Often found Go up to the winner Compared to the loser.

The cause of the association seen in previous studies may also be some third factor.For example, higher testosterone in men is linked to good health – And health may help people succeed in their careers.

Therefore, the association between male testosterone and socioeconomic status may simply reflect health effects on both. (For women, higher testosterone is linked to bad Being healthy, it is expected to be associated with high testosterone and low socioeconomic status. )

Look like this

It is very difficult to break down these processes and study only the effects of testosterone on others. With this goal in mind, we applied a causal inference approach called “Mendelia Randomization.” It uses the genetic information associated with a single factor (here testosterone) and influences that factor on one or more outcomes of interest (here socio-economic outcomes such as income and educational qualifications). Only isolate.

Human circulatory testosterone can be affected by environmental factors. Some, like the time, can be easily modified. Others are not, like someone’s health.

Importantly, socioeconomic conditions can affect cyclical testosterone. For this reason, it is not possible to identify what is causing what by looking at the link between cyclic testosterone and socioeconomic status.

This is why the genetic information is so powerful: your DNA is determined before birth and generally does not change during your lifetime ( cancer). Therefore, observing the association between socioeconomic position and genetic variation associated with testosterone strongly suggests that testosterone causes differences in socioeconomic outcomes. This is because other factors have much less impact on the variant.

More than 300,000 adult participants UK BiobankSeparately, males and females have identified genetic mutations associated with higher testosterone levels. We then investigated how these variants relate to socio-economic outcomes such as income, education eligibility, employment status, community-level deprivation, self-reported risk-taking, and overall health. ..

Similar to previous studies, we found that men with high testosterone had high household incomes, lived in disadvantaged areas, and were more likely to have a college degree and a skilled job. In women, elevated testosterone was associated with lower socio-economic status, including lower household incomes, living in less disadvantaged areas, and reduced likelihood of earning a college degree.

Consistent with previous evidence, higher testosterone was associated with better health in men, worse health in women, and more risk-taking in men.

However, there was little evidence that testosterone-related genetic variation affected socioeconomic status. No effects of testosterone-related genetic variation on any aspect of socioeconomic status, health, or risk-taking were detected in both men and women.

We found that women had fewer testosterone-related genetic mutations, so women’s estimates were less accurate than men’s. As a result, the relatively small impact of testosterone on women’s socio-economic status could not be ruled out. In future studies, larger female-specific samples can be used to examine female relevance.

However, in the case of men, our genetic results make it clear that previous studies may be biased by the effects of additional factors that may include the effects of socio-economic position on testosterone. Suggests to. And our results show that, despite the social myths surrounding testosterone, it may be far less important to success and life opportunities than previous studies have suggested.
