Why 20-Year-Old Men Today Have the Testosterone Levels of 70-Year-Olds in the 1970s

If it feels like something’s changed between your generation and your father’s and grandfather’s, science may back you up.

Recent data reveals a startling truth: young men today have significantly lower testosterone levels than their counterparts from just two decades ago. In fact, according to U.S. national health survey data, testosterone levels in men aged 15 to 39 have declined by approximately 25% since 1999.

A Shocking Trend Backed by Research

The data comes from the National Health and Nutrition Examination Survey (NHANES), a long-running program that tracks public health trends. Between 1999 and 2016, the average total testosterone levels in young men dropped from around 605 ng/dL to just 451 ng/dL. Even when accounting for lifestyle factors such as obesity, smoking, and physical activity, the trend remained consistent (NHANES source).

And this isn’t an isolated finding. The Massachusetts Male Aging Study, which tracked men aged 45 to 79 over nearly two decades, also recorded a generational decline in testosterone levels independent of age. In this study, median testosterone levels dropped from approximately 501 ng/dL in the late 1980s to 392 ng/dL by the early 2000s (MMAS study).

Soy boys

My wife says it is all the immunizations they standardized in the 1970s. Most of which BABIES get in the first few years of life.

Besides taking drugs and eating soybeans. Could be the fact that everyone tries to hide from the Sun (Vitamin D), Stay away from eggs and meat (Zinc). And collect participation trophies instead of winning.

I’ve said this for a long time. Young men LOOK much different today than the 80s. And certainly with regard to how they looked in the early 60s.

Given some problems I had very early regarding muscle development and some other lifelong things that nobody I am related to has, I would buy a lot of the theory.

I honestly doubt if it’s that high. What passes for young men these days couldn’t whip a sick kitten.

William Holden, Lee Marvin, John Wayne, Clint Eastwood, Cary Grant, Gary Cooper, etc., etc. vs. today’s actors.

We are not men we are devo.

Maybe that's behind the Decadence of Western Civilization.

Don't worry. Donald Trump has enough testosterone for the rest of them.

All the reasons that get mentioned, but I think the feminized life in a feminine society and a feminine culture we live in is part of it also.

Female behavior and standards is the state of normal today.

Being masculine is discouraged/shut down by much of modern society. The boys don’t have a full time dad, and they’re programmed by leftist women in schools. No exploring, no adventure, no Boy Scouts (who would have believed this 30 years ago???), etc. etc. Men have been culturally neutered. Their physiology follows their new place in this rather messed up civilization. Take these kids, band them up into troops in a Boy Scout Camp for 30 days, and then test again. Voila! (A theory...)

Yes, I’ve noticed the changed appearance of men — especially young men —these days. Another thing is their voices. I don’t have a TV, so I listen to a lot of radio. The males’ voices are higher and more nasal than men’s voices used to be. And — most annoying — many use what are usually thought of as female speech patterns, “uptalking” in particular. It’s rather odd and off-putting to listen to whiny-voiced, uptalking males chattering about professional sports and the traditionally male, manly athletes they seem to worship.

I blame soybeans and the prevalence of cereal “milk” substituted for real dairy milk. The estrogen-like substance in foods derived from soybeans is antipathetic to natural testosterone.
