Preview

Testosterone and its metabolites have important effects on neural development and specific behavioural and cognitive responses. Serum testosterone levels may have a U-shaped relationship to male cognitive function; higher and lower serum testosterone levels may be associated with worse function. In hypogonadal men, testosterone therapy improves cognitive function, mood, and libido. At usual dosages, testosterone does not increase aggression. It is unknown if testosterone supplementation to ageing men with declining testosterone levels might prevent cognitive decline and dementia.
