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.
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.
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).
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.
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.
Well you have no idea about "masculinity" given by testosterone implied, eg. Can two women reproduce? Or have the strength of a man?... and are thinking about "toxic masculinity" a term given to something else
Edit "Man needs testorones."
Edit "How mental and stupid would I be to think that everyone online has to agree with me... I am/was not expecting that to be clear... Everyone feel free to dislike, comment and be whatever you want to be and be happy in your lives"
Edit edit "since this has become a brainless comment section: " yes woman can still reproduce without a masculine Man, then what? Ffs... It's not like every single species has male and female with specific roles, right? Think about why society has deteriorated... Why families are being destroyed, by divorce rates increased and every single country has a birth deficit. Comes back to feminism of women (the toxic kind) and role problems for Men. Likewise toxic masculinity is also to blame.... ... you can't change biology. Man needs testorones. Man is a man and woman is the traditional woman, you know with a uterus (old fashioned and traditional, those dinosaurs yes) "
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.
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?
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
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.
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.
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.

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