MedicalResearch.com: What are the main findings of the study?
Answer: We found that older men with testosterone levels in the middle of the range had the lowest mortality risk. Having a low testosterone level predicted higher mortality, and there was no benefit of having a high-normal testosterone level. Men with optimal rather than high testosterone levels lived longest.
The other important finding was that men with higher dihydrotestosterone levels had lower mortality from ischaemic heart disease, suggesting that androgens may protect against heart disease in older men.
