testosterone

Correlating things to something like blood serum testosterone level would make more sense to me, than an entire sex.

With no testosterone at sight, could be easier for women to be more creative and take some risks probably.

It is absurd any border guard anywhere would feel the need to ramp up the testosterone in response to me.

Probably not, because it'd be insanely complicated to check testosterone levels on the subjects.

That men believe they are smarter might just correspond to higher levels of testosterone.

For instance, if one parent has much higher natural testosterone levels, is that dominant?

Exercise will make your testosterone go up for only a few minutes to an hour, which doesn't do much of a difference.

There was somewhat specious research in the past on what impact soy can have on testosterone levels and those have been widely debunked.

Taking estrogens without castration will leak out testosterone that can maintain muscle mass.

Rich or poor, I'm pretty sure I wouldn't be attracted to a woman with high testosterone!

Well, more accurately speaking it should reduce/get rid of [testosterone]-induced libidinal impulses.

Agreed overall, with the nitpick that I've never seen evidence that testosterone increases after sex.

On average, men tend to take more risks than women (a testosterone thing, hence the "having balls" expression).

That would be a way to fuel "testosterone-based behavior" and it would get really dangerous quickly.

I'm confused as to how this is a plus on it's own "- Testosterone / you become more dominant"

Once you do you will feel alot of social anxiety go away, since it's likely you would be "letting" go of your testosterone that way.
