Blacks have Higher T than whites and more prostate cancer

[malfeasance]

Mean testosterone levels in blacks were 19% higher than in whites, and free testosterone levels were 21% higher. Both these differences were statistically significant. Adjustment by analysis of covariance for time of sampling, age, weight, alcohol use, cigarette smoking, and use of prescription drugs somewhat reduced the differences. After these adjustments were made, blacks had a 15% higher testosterone level and a 13% higher free testosterone level. A 15% difference in circulating testosterone levels could readily explain a twofold difference in prostate cancer risk.

That study is almost 30 years old. Newer research suggests there is no link between testosterone level and prostate cancer.

Thanks for clearing that up, Troubador.
