High Testosterone: A Hidden Heart Disease Risk?

Men with elevated testosterone levels face an increased risk of heart disease, according to recent research. A comprehensive analysis involving over one million adults identified a 17% higher risk of coronary artery disease among these individuals. The study, conducted by researchers at the University of Cambridge, specifically examined testosterone levels that were high due to genetic factors.

Experts are issuing a strong warning to men who purchase testosterone supplements online. They suggest that such usage could lead to fatal outcomes. While testosterone supplementation is a recognized treatment for hypogonadism, a condition characterized by insufficient hormone production and often manifesting as fatigue and sexual dysfunction, the study underscores potential dangers for those using it without a medical necessity.

Testosterone levels naturally decline in men by approximately 1% annually after age 40, a change that usually goes unnoticed. However, the market for private testosterone supplements has seen substantial growth in recent years, now valued at over £700 million and expanding by nearly 10% each year. Companies are marketing these supplements to men as young as 30, promising benefits ranging from increased energy to muscle growth and improved sexual function.

Researchers emphasize that while boosting testosterone may be beneficial when medically indicated, the risks associated with using it for performance enhancement could outweigh the advantages. The study found no clear link between testosterone and coronary artery disease risk in women. Calls have been made for national guidance on the use of testosterone supplements.
