Men who suffer from erectile dysfunction (ED) are 70 per cent more likely to die early, a new study has found.  US scientists believe that the disorder may be linked to poor cardiovascular health, and suggested that men with ED should be screened for health issues that could cut their lives short.  ED is a term used to describe the inability to get or maintain an erection, according to the NHS. The condition can be caused by the narrowig of the blood vessels leading to the penis, hormonal problems, as well as injuries.
