Particularly, erectile dysfunction and poor morning erections, but not lower libido, were associated with increased mortality.
Further adjusting for total testosterone, free testosterone (total testosterone concentration that is not bound to any protein) or oestradiol (a steroid hormone) did not influence the observed risk.
The researchers concluded: “Sexual symptoms, in particular erectile dysfunction, predict all-cause mortality independently of sex steroids and can be an early warning sign of a poor health status.”

Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels.
