^Anthropology is not to be taken at face value. It is pseudo-science at best and has its origins in scientific racism. You will never know which race has more testosterone unless you examine every single person from every race individually.

It comes from a bone study in African and Caucasian women, because bone density is a pretty important health issue. They didn't set out to do a study to to promote racism. It's scientifically backed up. There are biological differences. Another example of this is the rates of sickle cell anemia
Three-quarters of sickle-cell cases occur in Africa. A recent WHO report estimated that around 2% of newborns in Nigeria were affected by sickle cell anaemia, giving a total of 150,000 affected children born every year in Nigeria alone. The carrier frequency ranges between 10% and 40% across equatorial Africa, decreasing to 12% on the north African coast and <1% in South Africa.[77] There have been studies in Africa that show a significant decrease in infant mortality rate, ages 216 months, because of the sickle-cell trait. This happened in predominant areas of malarial cases.[78] United States
The number of people with the disease in the United States is approximately 1 in 5,000, mostly affecting Americans of sub-Saharan African descent, according to the National Institutes of Health.[79] In the United States, about one out of 500 African-American children and one in every 36,000 Hispanic-American children have sickle-cell anaemia.[80] It is estimated that sickle-cell disease affects 90,000 Americans.[81] Most infants with SCD born in the United States are now identified by routine neonatal screening. As of 2016 all 50 states include screening for sickle cell disease as part of their newborn screen.[82] Patient advocates for sickle-cell disease have complained that it gets less government and private research funding than similar rare diseases like cystic fibrosis, with researcher Elliott Vichinsky saying this shows racial discrimination or the role of wealth in health care advocacy.[83]
