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).

“That’s mighty diluted estrogen”

Agreed, and because it doesn’t take much to make a change, it is excreted. Think about that.

I wonder what kind of Jody songs the military uses today?

My guess is that the theme song from Barney the Purple Dinosaur is probably the preferred cadence now, followed by a long break with juice boxes and string cheese.

Estrogen in the drinking water. Conventional wastewater treatment plants are not specifically designed to remove these micropollutants, including estrogens.

There are also a lot of microplastics in the water and air which mimic female hormones. Its well documented that young girls are reaching puberty earlier. I haven't seen a study on that, but those same female hormones could well decrease male testosterene levels.

If you have calluses then it’s a problem.

I’d like to see a study about the source of estrogen and efficacy of water supply sanitary runoff into the water system just don’t buy no offense
However, chemicals in plastics that reduce testosterone is proven

I believe there are natural products that increase estrogen production in men. Soy I think

Boy Scouts of America is no longer. It’s called Scouting America now, I believe, and allows girls and transgendered in. Homosexuals and transgenders are now allowed to be scout leaders. There’s no way I’d recommend that for any child. There are other groups now with traditional Christian values for boys, such as Trail Life and Royal Ambassadors.

Is it perhaps the time to revive the Boy Scouts? A literal and rhetorical question.

Most of the leading men today, the younger men especially, are a little bit effeminate. There’s no toughness. Steve McQueen and Clint Eastwood don’t compare with John Wayne.

It is similar to the most recent uproar regarding Sidney Sweeney in the American Eagle ad.
People are upset that a young lady with God given natural beauty(one in a million literally) is being promoted.

Beautiful women have been in advertisements for a hundred years. She is what they used to call a blonde bombshell.
The difference is she has not had plastic surgery to augment herself(to the best of my knowledge).

Yet, instead of saying, yes she is a beautiful young lady. The stupid liberal media is trying to trash her because she is White, blonde and pretty.

Similar to the fact the stupid WNBA players keep beating up the best player(Caitlin Clark) in the league that is going to single handily make them all wealthy.
