Testosterone Replacement Therapy (TRT) products for men have been linked to an increased risk of death, heart attack and stroke. Researchers found men who used testosterone therapy were 30 percent more likely to have a heart attack, stroke, or die after three years of use.
Furthermore, men who started the study with clear, unobstructed coronary arteries were just as likely to have a heart attack, stroke or die as men who entered the study with established coronary artery disease.
Testosterone therapy, such as the prescription topical treatments Androgel, Testim and Axiron, are used to help boost testosterone levels in men who have a deficiency of the male hormone. Symptoms of low testosterone include decreased libido and low energy.
