Finland, The Baltic and Testosterone

Finland and the Baltic states show an unusual amount of testosterone for Europe, and this shows up in measures like homicide, HIV, testicular cancer, digit ratio, and sperm quality. In some key ways Finland and surrounding areas look like tropical populations (and nearby Denmark is nearly the opposite). That is, it looks like there was significant female selection for “good genes” (Mixed ethnicity soldiers suggest that at least some of this is genetic).
