RANDY men fighting in the sack should break open a bottle of red wine, researchers say.
Chemicals in the drink called polyphenols have been found to help perk up a pecker.
The researchers, reviewing studies from the past 30 years, concluded that moderate amounts of red could increase sexual desire and performance.
It could also boost testosterone levels and male fertility, they say.
Polyphenols are powerful antioxidants that improve the functioning of the heart’s inner lining and blood vessels.
This increases blood flow to other parts of the body, including the sexual organs.
The Italy-based researchers also found that women who drank moderate amounts of red wine had more sexual desire than those who drank one glass or less, or were non-drinkers.
Additionally, they concluded that older women benefited as they tended to drink more heavily.
They wrote in the Journal for Clinical Medicine: “Given that age is usually inversely correlated with sexual functioning, these results seem very interesting.
“This could be due to an influence of both the polyphenols and the alcohol content in the red wine.”
Occasional drinkers of other types of alcohol, including white wine, benefited less.
The study also found that drinking too much alcohol affects sexual health as well as overall health.
