- Testosterone plays a key role in maintaining muscle mass, reproductive function, and cognitive performance.
- Fish provides nutrients that may promote testosterone synthesis (e.g., omega-3 fatty acids and vitamin D), but it can also contain contaminants that suppress testosterone production.
- This study investigated the association between fish consumption and serum testosterone levels in older Japanese males.
- Older males with higher fish intake had higher serum testosterone levels.
When categorized by the type of fish, higher intake of lean fish, but not fatty fish, was associated with higher testosterone levels.
These findings were published in Current Developments in Nutrition (2024; 8(4):102133).
