A recent study explored whether testosterone therapy increases the risk of heart problems in older male veterans with low testosterone and various health issues. This research involved over 200,000 men aged 40 and above. The participants had low testosterone levels and multiple chronic conditions but no history of heart attacks, strokes, blood clots, or prostate cancer.

The study focused on whether using testosterone raised the chances of serious cardiovascular problems, including heart attacks, strokes, or blood clots. Researchers looked at two common types of testosterone treatment: injections (intramuscular) and topical applications (transdermal). These treatments were grouped into three categories: current use, former use, and no use. Over an average of four years, they tracked 12,645 cardiovascular events.

The results were reassuring. For men without existing heart disease, using transdermal testosterone didn’t increase cardiovascular risk. In fact, it seemed to lower the risk slightly for those with pre-existing heart conditions. Similarly, intramuscular testosterone showed no significant impact on heart health for either group.

Researchers also examined how testosterone treatments were prescribed and used over time. They found that injections often restored testosterone levels to normal, while topical treatments led to lower but still improved levels. The team used medical records to track cardiovascular outcomes.

While the findings are promising, the study had some limitations. It focused on older veterans with many health problems, so the results might not apply to healthier or younger men. Additionally, the observational nature of the study means it can’t prove cause and effect. However, the large sample size and detailed analysis strengthen its reliability.

In conclusion, testosterone therapy didn’t appear to significantly increase the risk of major heart problems for these veterans. Still, the researchers recommend more rigorous clinical trials to confirm the findings. Until then, doctors should carefully weigh the pros and cons of testosterone treatment for each patient, following current medical guidelines. (Shores et al., 2021).
