The increased risk of cardiovascular events associated with testosterone therapy is significantly higher in trials not funded by the pharmaceutical industry compared to those that are.

Be cautious about the source of information regarding testosterone safety. Independent studies suggest a higher risk of heart-related events than industry-sponsored studies. If you are taking testosterone, ensure your doctor is monitoring your cardiovascular health closely, especially if you have other risk factors.
