Hi everybody, Cheryl Ackison here. Welcome to another edition of Full Measure After Hours. Today,

what's causing American men to lose testosterone? I've been hearing for at least a decade about

supposedly declining testosterone levels in American men.

And I thought at first, like many things, surely that can't be true. Sounds like a conspiracy theory.

Or we'd be looking urgently for the causes and declaring a health emergency. Because if as a society our men are developing

lower testosterone and we don't know why, it impacts everything from the collective behavior

of the male species to a very real ability to procreate. So I looked up the studies and I found

this is not just a conspiracy theory.

It's a conspiracy theory if it is that's true.

There is no dispute about this that as a society, men in America are declining in their testosterone levels.

In other words, a 30-year-old today has maybe 20% or 25% less testosterone than his father did at the same age.

That's shocking.

So then the studies that I looked for to get at the potential causes, they were quite old,

several years old.

And weirdly, none of the researchers that I contacted answered me, and none of their

institutions or publications where they had published would put them in touch with me or

agree to an interview.

So why don't the people looking at the potential causes, the things in our environment,

medicine, food, water, and so on. Why don't they want to do

on-camera interviews? I don't know. The studies that exist more recently that continue to confirm

the declining testosterone levels, they're primarily in the direction of how can we treat this,

what kind of medicine can we give? How can we correct it?
