>Chronological observation of testosterone fluctuations in relation to a change in evolutionary pressures
Has there ever been such a study conducted, either contemporarily or historically?
The thought arose when contemplating the decrease worldwide of testosterone and whether it was biochemical in nature (arising from an increase in environmental xenoestrogens and phytoestrogens), or whether it was some other factor, environmental or otherwise.
Sadly, I'm not a biochemist.
Bump to try and cut through the 8 shitposts that shouldn't be getting attention.
Last attempt at attempting to spark conversation.
Source on drop in testosterone levels?
I would imagine that a lot of testosterone triggers (being outside, being around large animals, feeling physically threatened, decreased need for physical activity in general) are now lower, and that may be a contributing factor. We can't ignore the estrogen stuff tho.
