An active sex life is the key to a longer life for men only if they are faithful to their partners, a new research has found.
Italian medical researchers have found that a healthy sex life means fewer cardiovascular problems for men.
"What was evident from the research was that men who had active sex lives and were faithful to their partners had fewer cardiovascular complaints and lived longer," the Telegraph quoted Emmanuele Jannini, coordinator of the research, as saying.
"Increased sexual activity produces more testosterone, which leads to less depression and a better cardiovascular performance which means an improved metabolism," said Jannini.
Jannini said the study has revealed that those who were unfaithful had a poor cardiovascular performance because they were "also coping with the increased stress of their infidelity."
She said that an increased amount of testosterone produced during sex was good for men because it burned off excess sugars and reduced the risk of heart disease.
"People who have diabetes especially benefit from a healthy sex life and an active sex life also helps avoid prostate problems for men," she added.
The Italian Society of Sexual Medicine carried out the study.
