Men with lower levels of the male sex hormone may be more prone to depression, suggests a study, which suspects that the testosterone level could affect key chemicals in the brain.
In a study of about 4,000 men aged over 70 by the University of Western Australia, it was found that those with lowest testosterone were three times more likely to be depressed than those with the most.
The research, which features in Archives of General Psychiatry , suspects that the male sex hormone may affect levels of key chemicals in the brain.
Though the researchers said further work was required to confirm their findings, the present study could be used to treat depression in older men by boosting their testosterone levels, the BBC reported.
