A new study from the University of South Florida shows that higher levels of testosterone appear to protect against asthma.
Researchers analyzed data on over 7,500 patients between the ages of 1 and 80 years old from the 2011-2012 National Health and Nutrition Examination Survey.
The population cohort was divided into three groups. The group with the highest testosterone levels had the biggest decrease (58 percent) in the odds of having asthma compared to the group with the lowest levels.
The trend was more pronounced in female patients – a higher testosterone level led to a 31 percent less chance of having asthma, compared to 3 percent in males.
The study, presented at the AAAAI meeting in San Francisco in late February, suggests that testosterone could protect against developing asthma.
