What if the perceived increase in numbers of androgenous and trans people has a chemical basis

I'd be willing to wager it's mostly due to it being safer to be "out" than it was just a few decades ago. Speaking as a 40-odd trans person, growing up in the 80's meant a much higher chance of getting your ass kicked or worse by your "peers" if you stepped out of line when it came to gender expression. I've always been what I am now, it's just that it's been safe to actually do it "out loud", at least for the past decade or so – that seems to be changing now that the right is radicalizing rapidly.
