From keeping your mind sharp and protecting you from injury to appearing more attractive to the opposite sex, testosterone works behind the scenes to keep you at the top of your game—and live longer to enjoy all its perks.
It Turns Her On
A recent study at Wayne State University pitted pairs of men against each other to win the attention of an attractive female using a simple, seven-minute videotaped competition. Researchers discovered that those men in the study with the highest T-levels were more assertive, took more control of the conversation and generally clicked better with females.
May Help You Live Longer
Researchers at the VA Puget Sound Health Care System’s Geriatric Research, Education and Clinical Center investigated mortality risk factors in male veterans over 40 years of age by measuring testosterone levels periodically for four years. They found that as subjects’ testosterone levels went down, their risk of death went up.
Toughens Up Your Ticker
According to a new 2010 study in the United Kingdom , having high testosterone isn’t what makes men susceptible to heart health issues—it’s having too little T that could be the culprit. The researchers say that low testosterone may be contribute to obesity, elevated harmful blood fats, and insulin resistance—each of which is a risk factor for heart disease.
Keeps Your Brain Sharp
In a study, Dutch scientists evaluated the cognitive performance of 400 men between the ages of 40 and 80 and noticed a direct linear relationship between T-levels and cognitive function among men ages 70 to 80. The higher their testosterone levels, the better they performed certain cognitive functions and tasks.
Fights Depression
Maybe it’s just a side effect of knowing you’re all man, but banking more testosterone may impact your odds of feeling depressed. When Australian researchers performed a cross-sectional study that compared the total and free testosterone—as well as the psychological and physical health—of nearly 4,000 men, they found that older men with lower free T-levels (below 6 ng/dL) had three times the risk of developing depression of men with high free T-levels (10 ng/dL or above).
