A study of 83,000 male US veterans over the age of 50 has found that replenishing low testosterone with patches, pills or gels can have a positive effect on cardiovascular health.
However, if testosterone levels did not return to normal despite the treatment, the benefits were not observed.
Overall, those who were successfully treated were 56 per cent less likely to die during the course of the follow-up than those who did not receive any replacement testosterone, 36 per cent less likely to suffer a stroke and 24 per cent less likely to have a heart attack.
This is the latest in a number of studies looking at the effects of testosterone on heart health, although results have often been conflicting. The US Food and Drug Administration (FDA) has issued a warning to doctors about the overuse of testosterone therapy in such cases, suggesting that it may in fact lead to increased risk of heart attacks and strokes.
Discussing the significance of the latest study, the researchers wrote: "It is the first study to demonstrate that significant benefit is observed only if the dose is adequate to normalize the total testosterone levels."
