I can think of a hundred bigger crimes

I can't think of a more reliable source than testosteronedecline.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.”
yeah, notably, estrogenincrease.com

Whoever drew that wavy line has no idea what a regression is

You are right it just looks like they used Excel + curve fitting.
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!
It's babbies' First Excel Sheet 😂
I remember fucking around with the same functionality and not understanding it, some 10 years ago. I guess this dood just found out about it too.

How much do you want to bet that the source is somebody trying to sell some sort of snake oil claiming to boost testosterone.

His tag says he beat testicular cancer and now he help
Def selling something
- Well that's interesting as testicular cancer will be closely linked to having 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.
Ask your doctor if anabolic steroids are right for you

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.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2674347/#:~:text=Consistent%20with%20data%20from%20a,Hadza%20and%20the%20Datoga%2C%20respectively.

That face when high testosterone turns out to be caused by lead in petrol.
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).
- The Male infertility
  i think male infertility is probably less of an issue when we consider that most people born now, do not want to have kids, based on the pure fact that it's too expensive, time consuming, and grueling in the modern era.
  Unless that's what you mean by male infertility. But last i checked that's not what that means. Perhaps even male infertility is going up because people want less children? Sign of the times sort of a deal, who knows, science is fucked! Or actually, it might be a result of better medical services, allowing people with worse fertility to have children now, when they previously wouldn't have been as likely to have children. Perhaps a result of decreasing infant mortality. Though i frankly doubt that's a significant factor.
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.
- No! Me more man juice, me more man! Mightiest man!
I can only infer the meaning of the graph but it seems to me that the sampling has increased which could shift the line as well.

Masculinity is on the verge of facing extinction

Why isn't this getting more attention?

Perhaps because masculinity itself isn't a moral good or requirement for survival? 🤔

As “requirement for survival” in modern day and age? Yes, we definitely don’t need it.
In prehistoric times masculinity is the reason why you live and breathe today.
Should what is masculine be redefined to fit today’s era? Hell yeah.
- Masculinity is a social construct.
  Whatever point you’re trying to make, you’re using the wrong words for it.
- As an effeminate male, I promise you I don't need masculinity to reproduce! 😁
- Ah yes, the only two functions, reproduction and opening jars /s
  Recently, scientists successfully induced the stem cell of a male mouse to transform into an egg instead of sperm.
  The resultant litter was in all respects normal and, while we are talking about baby steps (ha) with mice instead of humans, I'm sure that would be a when, not an if.
  The biggest immediate concern would probably be depression and osteoporosis. Pretty sure the depression wouldn't be very new, sadly, for anyone still paying attention to anything around them at all, but it doesn't need to be added to the pile for a demographic that already doesn't tend to reach out.
- Can two women reproduce? Or have the strength of a man?
  Yes to both questions.

The real crime is that fit line hahahahah

I love how redundant the degrees of freedom in that curve is "lets make it look like stience"

Yeah, it would have looked better with just a straight line fit. And 2020 does seem "statistically different" than 1970.
Edit: to be clear though, if lower testosterone means I live longer and with more hair, I'm all for it! My kids seem to be normal enough.
- Low testosterone can be a real issue. It'll reduce energy levels and limit bone and muscle strength. The right wing nonsense around it is obscuring some actual issues.
My guess is that they want to show a bump after 9/11 when "men went to war for freedom" or some shit.
Boa constrictor of best fit.

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.

Nice try Larry David
I will put my hand up as the symbol of bald sexiness..
I'm a bald bearded 6 foot man.
- Do you work in or near some chemical or nuclear industries or why do have 6 feet? /j
- Nice to meet you. I'm a 6-balled bearded footman.

Me with high T still able to enjoy colours and musicals 🥰

A crime, no, concerning sure.

What is causing the drop?

Lots of stuff.
https://www.medichecks.com/blogs/testosterone/why-do-gen-z-and-millennial-men-have-lower-testosterone
Tld;r:
Obesity, Microplastics, Fewer smokers, Stress and mental health problems, Tighter underwear, Diabetes, Higher indoor temperatures
- More sedentary lifestyle/not exercising
- Fewer smokers
  Why aren’t we making men smoke more?! Why isn’t the media talking about this?!
- Wait do people not wear boxer shorts anymore? Did I miss something?
Worse health in general it seems. And it's not as low as the graph the person shared
https://health.clevelandclinic.org/declining-testosterone-levels
An aging population.

I'm doing my part!

Wtf is happening with that fit?

Well you see, testosterone levels rose when Regan was elected, 9/11 happened, and The Apprentice launched.
It's basically science.
(this post was satire, and I'm sorry if it made anyone vomit)
- I need you to add these labels to the graph, for science.
It’s bullshit. I assume the data are bullshit, too.
That's the real crime

I have many questions, which I’m sure won’t be answered because conservative thinking doesn’t allow that. But mostly I wonder who are they testing and why?

Obese men from usa.

Why isn't this getting more attention?

Um, cause it's not that big of news and you're hyping shit just to get clicks.

Almost as if we don't live in a world where we need to have murder boners 247

Oh come on, everyone in normal countries knows that gun and tiny-penis truck ownership is directly correlated to miniscule genitalia, there's not really a surprise here

I've been hording it. Sorry.

Isn't that good for alphas? Who's complaining?

Oh no, not my testeroonies!

I'm definitely one of the low T people, and frankly I wouldn't care... If women didn't still only seem to want MANLY MEN™ .

Move to any city and seek out educated women.
Seems like not the only bell curve you are in the left of.
I don't know what hellhole you live in but that wasn't even true when I lived in one of the most conservative states in the United States.

Idk man after a vasectomy I creampied like 50 women so I would bet that the decline is caused by fear of having children who you have to be responsible for or wind up being a deadbeat.

If the decline is real, I'm almost sure it's our terrible meat heavy diet and micro plastics in everything.

I want to hear this guy say ng/dl.

APEOs are everywhere in the US.

The only crime I see here is the use of SI units! What's a ng/dl? ::: spoiler /s :::

200ng/dl? Is that nanograms per decalitre?

It's decilitre, 0.1L. Decalitre is daL.
- Ah, thank you for the correction. I still feel like it's a weird way to write measurements
