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.
Women Most Affected
The trend was more pronounced in the female population. A higher testosterone level among female patients led to a 31 percent less chance of having asthma, compared to 3 percent in male patients.
The study, presented at the AAAAI meeting in San Francisco in February 2019, suggests that testosterone could protect against developing asthma.
