Coffee can add a stir to sex life
Drinking two cups of coffee a day could perk up performance in the bedroom, a study suggests.
Research found that men who drank two cups a day were 42pc less likely than non-drinkers to report erectile dysfunction.
This fell slightly to 39pc for those who drank around three cups, the study of almost 4,000 men found.
The effect remained true regardless of whether men were overweight, obese or suffered from high blood pressure, the University of Texas study found.
However, the impact was reduced among men with diabetes, who have a high risk of erectile dysfunction, the study in the journal 'Plos One' found.
And doctors warned that drinking more than four cups of coffee a day can be dangerous, causing restlessness, tremors, irritability, insomnia and stomach upset. (© Daily Telegraph, London)
