What are the average testosterone levels in each African nation?

[deusmeister]

Has there ever been a study comparing the average testosterone rates (in men) per region/tribe/nation in Africa?

I would guess that West Africa has the highest because of Sudanids and South Africa the lowest because of Khoisanids.

I highly doubt anyone has cared enough to do such tests there.

There is no difference in testosterone level between different races.
