      I'm deeply confused by the worldwide drop in testosterone levels & sperm counts. It's a *huge* effect, too big to be explained by obesity. The most common explanation I see proposed is environmental contaminants. But I don't know if that's true, or which contaminants matter most.

      If you wanna confine a bunch of chickens in tight quarters, you breed and/or drug for docility. It’s the humane thing to do when you’re keeping a dramatically denser population than evolved traits were meant to serve. Unrelated: what on earth is going on with testosterone levels?

      Yep. My intuition says it's a social/psychological effect, but I gotta hit the data before I come to a real opinion.

          one angle to look at for this is urban vs rural T levels (urbanization could be dramatic enough to explain)- unfortunately it seems understudied, but there's a small study in South Africa showing no effect on men:https://www.nature.com/articles/1001493 …

          Also bad sleeping habits, which at this point ia worldwide phenomenon, have a huge affect on testosterone production

          it is a social adaptation of the society when the high death rate is excluded. Evolutionary mechanism.

          Trust your instinct. It's often more correct than the numbers.
