The Claim
Testosterone-replacement therapy has no statistically significant effect on the risk of stroke in middle-aged and older men with low testosterone, as indicated by a relative risk of 1.00 (95% CI 0.67–1.50) after at least 12 months of treatment compared to placebo.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In middle-aged and older men with low testosterone, testosterone-replacement therapy does not change the risk of stroke compared to a placebo when taken for at least 12 months.
See the scientific wording
Testosterone-replacement therapy does not significantly affect the risk of stroke in middle-aged and older men with low testosterone, with a relative risk of 1.00 (95% CI 0.67–1.50), indicating no statistically significant benefit or harm compared to placebo after at least 12 months of treatment.
Testosterone replacement in older men with low levels does not change the balance of clotting, blood vessel function, or inflammation in the brain's blood vessels, so the chance of a stroke stays the same as without treatment.
What the research says
1 studyIn older men with low testosterone, taking testosterone therapy didn't make them more or less likely to have a stroke compared to those who didn't take it, based on a big study of thousands of men.
