In this episode, Dr. Morgentaler and Dr. Brandon dive into the alarming drop in testosterone levels over the past few decades, why it's happening, and what it could mean for men's health, fertility, and our future.

00:09 – Declining Testosterone Levels: An Overview
Testosterone levels in men have been quietly dropping for decades—and it’s starting to raise big questions.

00:22 – Key Studies on Testosterone Decline
Major long-term studies show a 15% drop in testosterone over just one generation, and no one knows exactly why.

01:32 – Smoking and Testosterone: Surprising Findings
Oddly enough, smokers have higher testosterone—though no one’s saying it’s worth the trade.

04:08 – Environmental and Lifestyle Factors
From plastics to obesity, something in our modern world is messing with men's hormones—and we're only scratching the surface.

16:27 – Conclusions and Future Directions
We don’t have all the answers yet, but staying lean and rethinking our plastic use might be a good place to start.
