"Contrary to the postulated racial difference, testosterone concentrations did not differ notably between black and white men. However, blacks had higher estradiol levels. Mexican-Americans had higher testosterone than whites but similar estradiol and SHBG concentrations. Given these findings, it may be equally if not more important to investigate estradiol as testosterone in relation to diseases with racial disparity."

It's long been believed that black people have more testosterone than white's but the opposite is true. Apparently Mexican men have the most testosterone, then white and black men make around the same level with black men making more estrogen. This makes sense in the fact that black men and women tend to have less body hair.

"Elevated levels of estrogen adversely affect the development of male secondary sexual characteristics, often halting hair growth"

With black women, they make more estrogen and testosterone than white women comparatively, so they make more male and female hormones in general to where it balances out. Which makes sense with their libido being higher and more muscular frame while with the estrogen making of the widening of their hips and fat in breast and the butt. The increased estrogen production also accounts for the increased risk in black women to have develop fibroids as well as why many have exaggerated sexual features. Ex: Full lips, big eyes, big breast, wide hips, large butts. They also tend to begin their period at earlier ages. Then with the increased testosterone making their frame larger and their sexual libido greater.

“It is known that before menopause, African-American women have a higher breast cancer risk than whites, as well as higher estrogen levels,” Setiawan says. “It would be interesting to find out why their elevated rates do not persist after menopause, despite having comparatively higher estrogen levels.”
