Testosterone therapy (TT) does not significantly increase the risk of non-fatal myocardial infarction in men under 65 years without a history of heart disease.

If you are under 65 and have no history of heart disease, starting testosterone therapy does not appear to significantly increase your risk of a heart attack in the first three months. However, you should still discuss potential risks with your doctor, especially if you have other cardiovascular risk factors.

Why this rating

Observational cohort study using administrative claims data; while large and using robust statistical methods (doubly robust estimation), it lacks the controlled conditions of an RCT.
