As you surely know given your profile, testosterone is a hormone with many critical functions unrelated to aggression. Lack of sufficient testosterone causes osteoperosis, cognitive problems, fatigue, anemia, memory problems, hot flashes, and many other symptoms in men. It's essential for men's overall health and cannot be clearly disentangled from this role.

We do regulate the use of injected testosterone due to risks such as "roid rage" and enlarged heart among others. In the US testosterone is considered a Schedule III federally-controlled substance, i.e. a drug with medical uses that also has potential for abuse:

If a genetic mutation were known to code for impulsive violence, reduced IQ and little else, the story would be different. We wouldn't keep it around. MAOA-2R is such a gene. I know of no benefits to carrying this mutation versus its 3R or 4R variants. It causes a milder form of a disease called Brunner Syndrome, which confers a reduced IQ as well as increased violent aggression and reduced impulse control:

MAOA-2R lies in the same category as cancer-causing variants of BRCA1 or the allele for sickle-cell anemia in Western populations. We should treat it as such. There may also be non-genetic treatments for MAOA deficiency in the future. These should be explored and offered to those who might benefit. In the meantime we must accept reality. This gene, its effects, and its relative prevalence among racial groups (or "ancestral genetic populations" if you prefer) must factor into relevant public policy.

Given your comments thus far, I suspect that instead of engaging on the topic at hand you'll try to draw me further into some debate on whether men, seeing as they're so violent, should even be allowed to exist. Suffice it for me to say that the Greater Male Variability Hypothesis makes sense for humanity, and before "gender theory" reared its head we did a fine job keeping men in social spaces and structures where their more-aggressive tendencies were managed and expected.

Oh do you mean the gene that is as prevalent amongst the famously uncriminal Japanese as it is amongst African Americans?

I don't know, maybe those criminal men would be better with osteoperosis, cognitive problems, fatigue, anemia, memory problems and hot flashes than without, don't you think?

I personally don't think so.
