Alt Text: post that says dripping testosterone levels in men since 1980s is the biggest crime of the century.
The only crime I see here is the use of SI units! What’s a ng/dl? ::: spoiler /s :::
Time to assemble the Femboy army
Whoever drew that wavy line has no idea what a regression is
It’s when your T levels regress, duh
if you ever feel down and redundant look at the degrees of freedom in this fit and feel better
No it’s just R^7 regression! Testosterone levels will be negative by next week!
Edit: and male bodies were approximately 2000% testosterone in the 1940s!
You are right it just looks like they used Excel + curve fitting.
A useful approximation of normal T levels in humans can be seen in present day hunter gatherers in Africa. The Hadza tribe was shown to have an average level of 151pmol/l, well below that of what we see in societies such as America. We can, therefore, argue that the reduction of T levels in modern man over the last few years is a shift back towards the norm.
However, both populations experience suboptimal access to energy, and consequently maintain minimal levels of body fat and low BMI
You are citing a malnourished population.
Previous studies of non-western populations have revealed inconsistent associations between men’s testosterone levels and paternal or marital status. | Twenty-seven Hadza participants | Eighty Datoga participants
This is a comparitively small study, and one which contradicts other bodies of research.
As with male birds, it seems likely that testosterone facilitates reproductive effort in the form of male–male competition and mate-seeking behaviour, both of which interfere with effective paternal care.
Given the increasing social atomisation of the west (see:average age of fatherhood, number of children had, divorce rates), the hypothesis proposed by this paper implies testosterone levels in the west should be increasing not decreasing.
Look, I get the desire to debunk redpillers, but when we’re talking about a worldwide trendline in basic biology you’re going to need more research than this to do so. The Male infertility crisis is a genuine problem field experts are extremely worried about, hence the need for research and coverage by the mainstream (to stop snake oil salesmen being the main point of contact for this issue).
That face when high testosterone turns out to be caused by lead in petrol.
They love to pretend that they’re experts at biology but fail to grasp that it’s fucking complicated. More isn’t always better with hormones.
I can’t think of a more reliable source than testosteronedecline.com
yeah, notably, estrogenincrease.com
From the website:
The truth is that [the] whole project is (most of the time) quite inaccurate and error-prone, and often involves way too little data to really make a judgment, despite my best efforts. It also involves my amateur method of “age-adjusting” the results to be comparable. So this whole project is quite inaccurate and shouldn’t be used for serious conclusions. But if you understand the inaccuracies involved, you still may find it interesting.
“Listen, we know we’re full of shit, but that won’t stop your anti-trans uncle from posting our nonsense on Facebook.”
How much do you want to bet that the source is somebody trying to sell some sort of snake oil claiming to boost testosterone.
It’s a terrible graph anyway. The outliers haven’t been removed and I completely don’t understand the line of best fit that’s been drawn because it appears to be squiggly. How can it be squiggly, it’s a line of best fit, it’s an approximation. Oh and making some of the points green does not increase their validity.
You grok there are ways to fit data other than lines right?
I must be unaware of the arbitrary wiggly line of best fit.
His tag says he beat testicular cancer and now he help
Def selling something
Yeah I just hate those people who beat cancer then go on to share their findings with the world 🙄
A crime, no, concerning sure.
What is causing the drop?
Lots of stuff.
Tld;r:
Obesity, Microplastics, Fewer smokers, Stress and mental health problems, Tighter underwear, Diabetes, Higher indoor temperatures
This man is a “lunatic” because he’s worried about a change in the hormone levels of hundreds of millions of people?
Tell me you’re a misandrist without telling me you’re a misandrist.
Well, he is a lunatic for different reasons, but the reason for declining testosterone is not because of a crime, a plot, or correlating to a lack of masculinity, heavily masculine individuals still exist en masse, rather the average is being brought down by associated factors including average USA population increases in weight, diabetes, and of course age (See the Table below). Other factors that haven’t necessarily been proven to effect us on this scale, but probably do, is the move away from meat. While strictly veganism and vegetarian demographics have declined in recent years depending on who you ask, meat-replacement markets have grown massively in the last two decades.
There is no current widespread deficiency or emergency. Even with lower Testosterone levels most males are sufficient to remain healthy, even the chart shows that all but one blip of the collected data is above the 350 mark which is considered safe.
EDIT: Looks like consumption of fat contents in meat inversely correlates with testosterone, so vegans might actually be more masculine by that definition.
So you don’t think that people being more overweight, having more diabetes is “a crime”?
Do you realize that word use is not a reference to literal criminal law?
No I don’t think they’re a crime. That’s a really stupid question.
A quick literary search suggests there is no evidence linking a vegan diet with a reduction in testosterone. In fact, most studies found an small but significant increase in testosterone with specifically vegan men.
A simple google search shows nothing that backs up your claim, odd that you would have made it.
I used words like “not proven to” and “probably” as reasons to express doubt, but yeah it looks like it was a recent controversy with men’s health magazine and several studies going back about at least a decade disprove it citing a very clear inverse correlation with higher fat concentration in meats.

Could you please provide your source for that? I would like to read more on that.

To be clear the fat contents correlate with the lower testosterone, but the same was not true for high carbohydrate diets, so it’s a correlation specifically with high fat meats.
Lemmy and misandry, name a more iconic duo.
It’s clearly sexual selection; high testosterone results in early baldness, which in turn is deemed unattractive.
Thus, in order to save western society as we know it, we need to start worshipping bald men as the virile hotties we all know they truly are.
I will put my hand up as the symbol of bald sexiness…
I’m a bald bearded 6 foot man.
Nice to meet you. I’m a 6-balled bearded footman.
