Testosterone and Men are on the Decline


In my daily, awesome perusal of the internet, I came across this study in the Journal of Endocrinology and Metabolism (a very reputable journal, as far as I can tell from the journals it is cross-referenced with) concerning a Population-Level Decline in Serum Testosterone Levels of American Men. It was the largest, most comprehensive study of it’s kind measuring testosterone levels of men from different generations as they aged over a 17 year period (1987-2004). The results show a population-level decrease in testosterone (that means, for example, men who were born between 1916-1919 were measured to have lower testosterone than men born between 1940-1945 when aged the same number of years, look at this graph) that is consistent with “population-level decline in sperm counts and increasing incidence rates of certain reproductive disorders in men, especially in some Northern European countries.” Maybe Paula Cole was onto something.

The study does show what had already been known: that testosterone decreases linearly with age. However, it is surprising that we can see such a noticeable decrease in testosterone levels for no apparent genetic reason (further proof that relying on hundreds of thousands of years of evolution for mating dynamics is a huge mistake, stop talking about cavemen please, cavemen didn’t have mixed race girls).

Also, while this study was only done in the U.S., it’s large sample size (N=1709) and close matching with trends seen in other parts of the world (at least in developed nations) suggest that something is at work here. Feminism? Corporate culture? McDonalds? Acceptance of homosexuality? Yellow #5?!?!?

If you’re a good scientist, you may wonder why this study was done on older men. It’s because they were trying to measure how testosterone levels decrease with age. They just happened to stumble into this surprising result of decrease in testosterone over generations.

It’s very interesting to me how it is natural to assume that people aged faster back in the day, after all, people are living longer now than they ever have. However, older men maintained (in this study) higher testosterone levels than the next generation at the same age. Your dad had the right to call you ‘son’, son.

The good news is that girls are hotter than they’ve ever been, and the testosterone is being sucked out of society. Sounds like shooting fish in a barrel to me.

I am a scientist, but this is not my field. If you’re interested in a real editorial by someone who knows what they’re talking about, read this.

  1. Hey science guy….give us some studies on fat people and ideas for their eradication. That seems to be your strong area.

    My question is what’s going on with women? I don’t feel like reading the study and since you obviously did, how are our hormone levels doing? Did the study discuss if women have sucked all the testosterone out of men leaving them as “beta” sniveling little bitches? Socially this could perhaps suggest a decrease in abortions, “I can help myself thank you” (eww) and perhaps an increase in homosexual, masculine looking women 😉
    If there has been an increase in the testosterone levels of women or even a decrease in the estrogen levels do you have to worry about the hottness of the fish you’re shooting in barrels? Let me know your thoughts Birthday Boy.

  3. this explains the decrease in alpha males, and the ones still left are truly treasures!

  4. Maybe because as people are getting smarter and working corporate more they don’t need to use that much test. Older generations actually had to really work. I mean how much test does it take to press enter on a keyboard?

    Just a thought

  5. Me, I would love to know about estrogen levels in women. I would guess that they’re going up. They don’t seem to have the same fertility problems men are starting to have, and the influx of estrogen into our society is unmistakable.

    Reminds of a quote I read in “The Way of the Samurai”. Take some of this ancient knowledge for your bitch assess, “The brave men of old times were for the most part rowdies. As they were of the disposition to be out running amuck, their vitality was strong and they were brave. When I had doubts about this and asked, Tsunetomo said, “It is understandable that since their vitality was strong they were generally rough and went about running amuck. These days rowdiness is nonexistent because man’s vitality has weakened. ” This was written over 300yrs. Ain’t nada new under the sun……Bitches.

      Man I agree with you, today’s men do not have so great levels of testosterone because they are not as fit as men before were. Also the diet has been feminized you need fat (saturated, monounsaturated) to produce testosterone. Also men do not go to sun as much as before, and vitamin d is also very important for testosterone. Also their minds are feminized and they are constantly told to be calm and peaceful and not to cause any kind of trouble.

    the spread on the noted graphs is alarming-could this be yet another study that simply bends the data to the will of the abstract/PI?

  8. I follow your blog for a long time and must tell you that your articles always prove to be of a high value and quality for readers.

  9. This is very hot info. I’ll share it on Facebook.

    I am curious to know how the increased levels of estrogen in the drinking supply is affecting males. There are fish in the rivers of the united states that have become A-sexual because of the estrogen and other contaminants in the water supply from feminine products and other prescriptions being flushed down the toilet.

    I can’t find any article on this? They tested the fish but not people!! Seems logical enough. If America is turning itself gay that would be ironic with all of the states reversing gay marriage

  12. Testosterone levels have not suddenly been reduced to a fraction of what they were in the 1940s (and for tens of thousands of years before) by magic. They are deliberately putting testosterone suppressants in our food, water and medicines. Grow your own food
