That's not the reason. It's related to the ABCC11 gene.

Basically, if you have dry ear wax = no body odor,
If you have wet ear wax = body odor.

80 to 95% of East Asians (Chinese, Koreans, Japanese) have dysfunctional ABCC11 gene so 80 to 95% of them don't have body odor.

Since a big percent of the race don't have body odor, there isn't the same sort of culture as other races to buy perfume since the primary purpose of perfume is to mask body odor.

Body odor is related to ABCC11 gene and not to body hair or testosterone.

This isn't what I'm talking about.

East Asians have less odor in general (roughly 80-95%) because of the ABCC11 gene.
You can tell if you have body odor by the type of ear wax you have. If you have wet ear wax you'll have stronger body odor and if you have dry ear wax you'll have much less body odor. Most east Asians have dry ear wax, probably most Chinese here don't even know there's such a thing as wet ear wax.

East Asians commonly have the "AA" genotype at the ABCC11 gene SNP rs17822931. The ABCC11 gene encodes a protein that helps transport organic molecules out of cells. For east Asians with the AA genotype, this protein is broken down early and doesn't function, so these molecules stay inside cells and aren't secreted.

Basically, in the majority of east Asian population with AA genotype, fewer odor causing compounds are secreted so they have much less body odor.

Edit: regarding adrostenone from your quote,

In AA genotype individuals, due to nonfunctional ABCC11, the sweat contains fewer or none of the steroid precursors. Because of that androstenone is either secreted in very low amounts or not at all.

Depends on whether you're AA, AG or GG genotype.
So that odor you're talking about from testosterone, if you're AA, you either secrete very little of it or not at all.
I edited this in in my previous reply regarding androstenone:
Due to nonfunctional ABCC11, the sweat contains fewer or none of the steroid precursors. Because of that androstenone is either secreted in very low amounts or not at all.

AA = inactive ABCC11, low or no body ordor
AG = partially active ABCC11, moderate body odor
GG = fully active ABCC11, strong body odor

Personally, I didn't experience the odor thing from puberty that you're talking about.

So basically, the short version is that testosterone doesn't affect where hair follicles are located but it can affect the growth and thickness.

So like if you don't have the follicles for chest hair, having high or low testosterone won't make a difference.

I didn't read the massive evolution of humanity thing, but it doesn't soj d like something I would care about. I'm just explanation why some groups might have stronger body odor and some have less and the connection between that and the main topic about type c and perfume.
