Being sexually active helps reduce risk of heart disease in men, a new study indicates. The study found an association between frequent intercourse and reduced risk of heart disease.

To examine the correlation between sexual activity and heart health, researchers followed up 1,000 men aged between 40 and 70 years who participated in the Massachusetts Male Aging Study, which began in 1987, for 16 years.

It was found that men having regular sex were up to 45 percent less likely to develop life-threatening heart disease compared to those had sex once a month or less. The association was significant even after other risk factors like age, weight, blood pressure and cholesterol levels were considered.

This is an association, not necessarily a cause and effect relationship even though there is such a possibility, the researchers cautioned.  Healthier men tend to have stronger desire and manhood to make love more frequently in the first place.
