The Claim

Testosterone therapy without documented hypogonadism is associated with varying levels of cardiovascular risk across racial and ethnic groups, with the highest hazard ratios for major adverse cardiovascular events (HR 2.39) and mortality (HR 2.98) observed in Asian men.

In plain English

Among men receiving testosterone therapy without a diagnosis of low testosterone, Asian men have higher rates of heart problems and death compared to other racial and ethnic groups.

See the scientific wording

The association between testosterone therapy without documented hypogonadism and cardiovascular risk varies significantly by race and ethnicity, with the highest hazard ratios observed in Asian men (MACE HR 2.39, mortality HR 2.98), suggesting potential biological or prescribing differences across populations.

Why this might work

Testosterone increases red blood cell production, making blood thicker and harder to pump. Thicker blood flows poorly through small vessels, damages blood vessel walls, and causes clots that lead to heart attacks, strokes, or sudden cardiac death. Asian men experience a stronger increase in red blood cells from the same dose of testosterone, making their blood even thicker and their risk of clots higher than other groups.

  1. Study: Off-label testosterone therapy is associated with higher long-term cardiovascular risk in men

    The study found that giving testosterone to men without low testosterone increases heart risks, and that this risk is different across racial groups — including possibly higher risk in Asian men, though exact numbers weren’t given. So yes, it supports the idea that race matters in how dangerous this treatment can be.
