Yeah, but a few paragraphs later, we have this:

"According to Lokeshwar, potential causes for these declines could be increased obesity/BMI, assay variations, diet/phytoestrogens, declined exercise and physical activity, fat percentage, marijuana use, and environmental toxins."

My personal, totally unsupported hypothesis: society is simply kinder and gentler now. As evidenced by the high testosterone in prison populations, this hormone responds to environmental threats of potential violence.

Loved reading that. I don't know if it's true, but I hope so.

It's probably not the case that testosterone being lower is a result of society being kinder and gentler, but that society is kinder and gentler as a result of the lower testosterone.

Well, there might be a positive feedback loop factor implied, even if other factors might affect the rise of kinder society and the decrease of testosterone.

That’s funny as the first time I heard about feedback loop was in college biology courses, when we were taught how women hormones interactions are modelizable.

I didn't read it in the former way personally. Your sentence confused me at first with that assumption for you to disprove.
