Low serum testosterone levels are associated with increased risk of mortality in a population-based cohort of men aged 20–79.

Aims: Although the association of low serum testosterone levels with mortality has gained strength in recent research, there are few population-based studies on this issue. This study examined whether low serum testosterone levels are a risk factor for all-cause or cause-specific mortality in a population-based sample of men aged 20–79. [ABSTRACT FROM PUBLISHER]
