This could be a question that men might be routinely asked as part of a screening programme for propensity to heart disease. A new research study in the US found that with all other factors held constant men who had sex twice a week cuts down the risk of heart disease by half. In addition, having sex once or twice a week in winter can boost the immune system and reduce the chances of catching colds and flu, according to researchers at Wilkes University, Pennsylvania.
They found it boosted levels of immunoglobulin A or IGA which binds to organisms that invade the body and then activates the immune system to destroy them.
So now you know - and I have had viral infection and a cold this winter already!!
