NIH Study Finds Testosterone May Limit Brain Tumor Growth in Men, Offering New Treatment Insights
A study funded by the National Institutes of Health (NIH) and conducted by scientists at the Cleveland Clinic has revealed that male hormones, particularly testosterone, may play a crucial role in limiting the growth of brain tumors in men. The research focused on glioblastoma, a type of brain cancer more prevalent in men. The study found that the loss of androgen hormones, such as testosterone, in a preclinical model of glioblastoma led to tumor growth by inducing local inflammation and stress hormone production. Analysis of data from over 1,300 men with glioblastoma showed that those receiving supplemental testosterone had significantly improved survival rates. This finding suggests that testosterone may help regulate the brain's immune response, preventing tumor progression.
