The Testosterone Decline in Men

Wanna check out the Youtube version of this article?

Now onto the article…

I was watching Joe Rogan talk with Sam Altman recently and he was going on about the testosterone decline in men over the last few decades.

And he was going on and on about the impact of plastics in food and how this was the main cause of this decline. He kept citing a Dr. Shanna Swan, who has apparently researched this for a long time.

So I looked it up and saw that he’d actually interviewed her sometime back.

According to her the decline in testosterone in men ‘correlates’ almost perfectly with the rise of plastics.

And I was yelling at the screen… “No, no, no Joe…. please…. don’t say you believe this nonsense! I actually like listening to your podcast and think you’re a smart guy, but I am losing respect for you with this BS!”

Today i’ll explain my view and why this woman is talking complete garbage.

It is true that testosterone levels have been declining in men

There was a recent release of findings from a long-term investigation of aging in about 1,700 Boston-area men. Data from the men were collected for three time intervals: 1987-1989, 1995-1997, and 2002-2004.

While a man's testosterone level will fall steadily as he ages, the researchers observed a speedier decline in average testosterone levels than would have been expected with aging alone.

"The entire population is shifting somewhat downward we think," Dr. Thomas Travison, an expert on the subject, said.

And testosterone deficiency has a prevalence of 10%-40% among adult males and is on the rise.

Why is testosterone important again?

Testosterone has a lot of important functions as you can see in the chart above.

Loss of testosterone is associated to things like loss in muscle mass, fatigue, depression, loss of facial and body hair, brittle bones, etc.

In essence, you need testosterone. And the more you have, the better it is generally.

They have concluded that aging affects testosterone for a long time

The scientists state that “beginning around age 40, men’s testosterone levels start to gradually drop by about 1 to 2% each year.”

This chart below shows a rough estimate for just how much you can expect it to drop over the course of your life.

What else generally declines in age?

You guessed it! These biomechanics!

Why? Because the other thing that happens as you age is that you grind your teeth down and lose ‘vertical’ in the mouth.

A ‘correlation’ between plastics and the decline of testosterone in men?

This Dr. Shanna Swan that Joe Rogan interviewed points out that the decline in testosterone of men over the last few generations correlates perfectly with the use of plastics.

And that they are measuring higher and higher levels of plastics in humans.

Therefore she makes the conclusion that there must be causation. And that plastic is one of the main causes for the decline in testosterone.

But wait a minute… there are like a thousand things that correlate with this decline in tesosterone. Things like obesity, the rise in neurological disease, the rise of orthodontics, etc.

They all more or less follow this same curve!

And so to me it is just crazy that she attributes it to plastics. Especially since I know that she is wrong.

There is one very clear reason for the decline in testosterone in men

So as you may have guessed…the answer is these biomechanics. And I’m going to ask you to think logically again about this example.

My testosterone has increased massively the last couple of years. I do not get it measured but I can feel it.

Sometimes it is so intense that I cannot even control it. I’ll be in my office and I’ll just yell or something when it gets too intense.

Plus I have not done anything else besides these biomechanics during this time. Did i try to reduce my consumption or exposure to plastics? Clearly no.

And yet somehow I am able to very clearly counteract the effects of it and have my testosterone continually increase the past few years. Why?

Well, I am willing to bet that the correlation between a person’s ‘structure’ and their testosterone is going to be nearly perfect.

As you improve your skull and skeleton, your testosterone will improve.

I’ve felt this with each cycle of improvement the past decade. And I have no doubts there is direct cause-and-effect.

So yeah… sorry Dr. Shanna Swan. I do not recommend you try to push your theory very far. As me and many others will be making a mockery of it in the future ;)
