Higher levels of testosterone in men may help protect them from developing multiple sclerosis (MS) and other autoimmune diseases, say researchers at Northwestern University in Chicago. Results of their mouse study were published in the Proceedings of the National Academy of Sciences.
The researchers discovered a “guardian molecule” that is triggered by testosterone and appears to protect against MS. When they gave this protective molecule to female mice with MS, it eliminated the symptoms of the disease.
Multiple sclerosis is three to four times more common in women than men, and women typically develop MS earlier in life. This Northwestern discovery could help lead to new treatments for MS, according to the researchers.
