UCLA FSPH-led Study Prompts FDA Investigation



  • A new UCLA study led by Professor of Epidemiology, Sander Greenland, underlines recent research that reveals that testosterone therapy is associated with a significantly higher risk of a heart attack.
  • Unlike previous studies, the study encompassed both men 65 or older and men under 65. The researchers observed that those with a history of heart problems in the younger group had a two- to threefold increase in their risk of having a nonfatal heart attack. Men over 65, regardless of their health history, had a twofold increase in their risk of a heart attack when taking testosterone therapy.

The results emphasized that "patients and their physicians should discuss the risk of heart attacks when considering testosterone therapy." -Dr. Sander Greenland


  • The FDA has announced it is reviewing the safety of the widely-used treatment, stating that it is “investigating the risk of stroke, heart attack and death in men taking FDA-approved testosterone products.” It also urged doctors to weigh the potential risks and the benefits of the FDA-approved testosterone treatment when prescribing such to patients.
