How Testosterone Levels Impact IQ | 33 Ways Testosterone Boosts Intelligence
This may be a triggering one for some people, but it's a topic I've been thinking about for a long time. Testosterone has been declining in men and women across the population. At the same time, IQ scores have been trending down. My thesis is that these two things are connected, and what that means for society is worth talking about.
This is also a preview of some of the material in my upcoming book, Testosterone: The God Molecule.
The Testosterone Decline Is Real
Studies have shown a major drop in average testosterone levels over the past several decades.
Research published in the Journal of Clinical Endocrinology and Metabolism found that testosterone levels in men dropped about 1% per year from 1987 to 2004. That's a 17% decline over 17 years. If the average was 1,000 ng/dL, you'd be looking at 830 by 2004.
Since then, estimates suggest another 20 to 30% decline. So if you stack it all together, we're probably looking at a 40 to 50% drop in average male testosterone since 1987.
I was born in 1993. That means in my lifetime, average testosterone in men has roughly been cut in half.
Similar trends have been documented in Sweden, Denmark, Japan, and across the developed world.
What's Causing It
A few things are driving this.
Lifestyle. More sedentary behavior, worse diets, less physical labor, more time indoors, and rising obesity rates all push testosterone down.
Environment. Endocrine-disrupting chemicals in plastics, pesticides, and industrial waste products are now everywhere. They've been directly linked to reduced testosterone production. The world is a contaminated cesspool when it comes to these chemicals, and I think we're past the point of repair on a societal level.
Health factors. Chronic stress, poor sleep, and rising rates of metabolic disease like diabetes are all crushing hormonal health.
You're not going to picket city hall and stop them from putting fluoride in the water or stop the use of plastic. The only thing you can control is what you do for yourself and your household.
IQ Is Also Falling
Research points to a global decline in IQ scores, often called the Flynn effect reversal.
A study by Bratsberg and Rogeberg found that IQ scores among Norwegian men born between 1962 and 1991 have decreased. More recent data from the UK, Denmark, and Germany shows the same downward trend.
A 2020 study published in Intelligence suggests that average IQ scores in several Western countries have dropped about three to five points since the early 2000s.
That sounds small. It isn't. Even a few-point shift in average IQ has massive effects on how a population thinks, behaves, and interacts.
Why IQ Is Dropping
A few of the usual suspects.
Education. A shift toward standardized testing and rote learning doesn't build critical thinking.
Technology. Constant screen time, smartphones, and social media affect attention spans and memory. Kids now have access to screens from the time they're out of the womb.
I was at a conference about seven years ago where the CEO of Intuit was speaking. Someone asked him what they were studying for the future of their company. His answer stuck with me. He said they were studying the brain development of kids under 12, because their brains are developing structurally different than human brains have in the past. A software CEO was studying child neurodevelopment because he knew the human brain itself is changing.
Environmental toxins. Heavy metals, air pollution, and other neurotoxins impair cognitive development the same way they impair hormonal health.
How Testosterone and Cognition Are Connected
Testosterone has direct effects on the brain.
It safeguards brain cells from damage, promotes neurogenesis, and supports memory, focus, and problem-solving. It influences mood, motivation, and stress resilience. It reduces anxiety and depression while increasing energy and drive.
If you're constantly stressed and stuck in fight-or-flight, you can't think critically. You can't solve hard problems. You can't build a business. Testosterone is what helps you stay out of that state.
What the Research Actually Shows
Here's a sample of what the literature says about testosterone and cognitive function.
A 2004 study found testosterone supplementation enhanced verbal and working memory in older men. A 2007 study linked higher testosterone to better attention and concentration. Studies in 2011 showed men on testosterone therapy had better learning capacity. A 2002 study correlated optimal testosterone with higher general cognitive scores.
For brain health specifically, a 2003 study showed testosterone helps prevent neuronal death. A 2010 study found it reduces oxidative stress in the brain. A 2013 study linked testosterone treatment to increased neurogenesis in the hippocampus, the brain's memory center. A 2008 MRI study showed men with higher testosterone had greater brain volume in cognitive regions.
For mood, a 2014 study found testosterone reduces anxiety. A 2013 study showed it significantly reduces depressive symptoms. A 2016 study linked higher testosterone to greater stress resilience.
For specific skills, higher testosterone improves verbal fluency, spatial reasoning, executive function, mathematical problem-solving, and even creative cognitive performance.
For long-term cognitive health, a 2017 study found men with higher testosterone had slower rates of cognitive decline. A 2018 study showed maintaining healthy levels can lower Alzheimer's risk.
The list goes on. Better body, better brain.
The Society-Level Problem
Now scale this up.
If average testosterone has been cut in half over a few decades, what does that do to collective motivation, drive, energy, and resilience? What does it do to productivity? To innovation? To healthcare costs?
There's a feedback loop here. Lower testosterone causes lower cognitive function, which makes it harder for people to even recognize and solve the problem of low testosterone. It's hard to see what you don't see.
There's also the genetic angle. If women have lower in-utero testosterone, the male children they carry receive less testosterone during development. Dr. Shanna Swan wrote a book called Countdown about this. If current trends continue, we may have a real problem propagating the species.
My Take
I had very low testosterone at one point in my life. I got it addressed through therapeutic testosterone, and my life has been dramatically better since. My brain fog cleared. Learning got easier. Memory improved. I felt smarter, and I was already someone who got good grades and considered himself pretty intellectual.
This isn't a video to condemn anyone or call the world stupid. It's a video to point out that hormones shape how we experience reality, and the data on both testosterone and IQ is pointing in the same direction.
You can't control the fluoride in the water or the plastic in the food supply. What you can control is your own bloodwork, your own habits, and your own hormone levels. Get tested. Find out where you stand. Then decide what you want to do with that information.
The book, Testosterone: The God Molecule, goes much deeper into all of this. Stay tuned.

Hey everybody. This is Hunter Williams. I hope you were doing amazing wherever you are at in the world. And today's video is going to be about the decline in testosterone and IQ. Now this may be triggering to some people, but basically this is a video that is based on some of the material that's actually going be released in my upcoming book, which is called testosterone, the God molecule. Basically it kind of looks as, uh, It looks at our mental, emotional, and spiritual health through the lens of our hormones, particularly testosterone.
And one thing that I have noticed over the last few years is there is a massive decline in testosterone in the population, not just among older men, but among men of all ages and really women too. Then also too, there seems to be, this could be me, when I went through evidence in preparing this video, it seems that there's a decline of IQ in terms of how intelligent people are. And really intelligence as it relates to being able to think critically to be able To read to people to write and all those things. So even just a few point decline in IQ can have massive shifts and outcomes in the population as a whole.
And what I've noticed is that as testosterone has declined, IQ has as well now, These could be completely independent of each other. But my thesis for this video is basically these are very interconnected and not just for men, but for man and women as well. So today's video. Is going to be about how the decline in testosterone levels is manifesting in the IQ of the population. And then what that means for society as a whole. So I know it's a little bit different than what I normally talk about, but in the spirit of my upcoming book release, which I'm going to be talking more
about soon, um, I wanted to explain my way of seeing the world. And the way I came about this is obviously I had very low testosterone at one point in my life, and I got that address through using, uh, therapeutic testosterone. My life has been so much better since then. What I noticed is that once I was on therapeutic, testosterone, my levels were optimized. I felt a lot better. seemed to be a lot smarter and I'd always got really, really good grades in school and considered myself pretty intellectual.
But I noticed that once I got on testosterone, it was easier because I had less brain fog to basically learn things, to process information and to store things in my memory. So I noticed that my IQ seemed to go up as my testosterone levels were optimized. And unfortunately, we're kind of in this point in the population where testosterone is declining. I think that's beginning to manifest in collective IQ of the human species. So this is not a condemning video. This is not a judgmental video. And I want this to be information that you can take and use it as you see fit.
Again, I'm not saying this, to say the world is stupid or anything like that, but I wanted to show you how important our hormone levels are as it relates to our intelligence. Because if you look at our Intelligence, that's kind of like where the World moves. So if we're moving in this direction, where The world Is getting collectively dumber, for lack of a better word, it could be dangerous in terms of what collective Reality is brought about through our hormone levels. And I think at the end of the day, our hormonal levels are directly tied to whatever reality, the world or reality is created in the word because ultimately,
uh, The collective reality based on the decisions that everyone makes and the sum of those together. So Again, this is not a judgmental video. It's just the nature of what it is. And again, these may be completely independent of each other, but this my own interpretation of the world. Most importantly, before I pull up the slides, I noticed that I interpreted reality different. When my testosterone was optimized, ultimately this is what my book is about. We experience a different world when our hormones are optimized versus not optimized.
And the most important part of this, is that we optimize our hormone so that, we see the world much more from an objective sense of reality. Uh, versus a subjective, which would mean that we don't have optimized hormone levels. So ultimately that's what it's all about. And, uh, this is, you know, obviously got some health stuff in it, but it has some of my philosophy slash writing stuff and it as well. Hey, maybe this video won't get a lot of views. That's totally okay. But it was just something for me that I wanted to do and, is out there and hopefully makes you more interested in reading the book that is coming out.
So without further ado, I'm going to share my screen and today we are going talk about testosterone and the decline in IQ. All right, this video is testosterone IQ, the great decline. So let's get into it and let us kind of understand where I am coming from. Let's look at the first decline of testosterone levels. Obviously I don't think we need a lot of evidence to support this, but let just look what we have to show this. Studies have shown a significant reduction in average testosterone level in men over the past several decades. So basically this was research published in the journal, the Journal of Clinical Endocrinology and Metabolism found that testosterone levels in men dropped
about 1% per year from 1987 to 2004. So let's be clear. What's that? 17 years. Sort of looking at about one percent. That's 17% decline. For instance, if the average was a thousand, we would be looking now at an average of 830 total testosterone. So that may seem insignificant. However, when we look at the last two decades, we knew the year now is 2024. We're looking at since 2004. It's hard to get a gauge,
but estimates indicate a further decline of around 20 to 30%. So just for round number standpoint, let's say another 20%, which would be, you know, a fifth of that, which we're probably looking, somewhere, Let's just say a quarter for our numbers to another 200 point decline, which is now 600. So we're really looking at since 1987, most likely, and it's hard to get an accurate gauge on this, but in my opinion, we'll probably looking it somewhere close to like a 40 to 50% decline in the testosterone in men just since 1997. And I was born in 1993. So we're looking
at like, you know, really in my lifetime, more or less a having of the total testosterone. So there's also been similar trends observed in various countries, including Sweden, Denmark, and Japan. Global data indicates that men today have significantly lower testosterone levels compared to those in the early 20th century. And again, before that, did we even really know what testosterone was? No, I don't. I think you went back to 1750. You said the word testosterone, maybe people didn't know that was, but that would just be my guess compared Now, let's look at what caused this.
So, you know, is it engineered or is just an unintended consequence? I don't know. That's outside of the scope of this video, but let us look lifestyle changes. Obviously, there is increased sedentary behavior, poor diets, lack of physical exercise, and rising obesity rates. These all contribute to lower testosterone levels. The modern lifestyle today often involves less physical labor and more time spent indoors, which obviously, that alone is going to contribute a lower, lower testicular levels now. Let's look at the environmental factors. I think there's much more on this front that is probably causing the low testosterone.
So exposure to endocrine disrupting chemicals found in plastics, pesticides, and other industrial waste products have been linked to reduce testosterone production. These chemicals are now ubiquitous in the environment and they affect populations worldwide. Obviously, the world is a contaminated cesspool now as it relates to the endocrine disruptor chemicals. In my opinion, we are beyond the point of repair. No amount of protesting, government lobbying, anything like that is going to really change the state of affairs. So what can we do, at least from my lifetime and practical purposes for me and my household and family and friends and the people I care about?
We have to change ourselves because I don't think you're going down to town hall or city council, wherever it is, and picket them to make any changes. You're not going stop them from putting fluoride in the water. Your not gonna stop the ubiquitous use of plastic. It's just really not happen. We also have health factors. So there's increased stress levels in the population, much more poor sleep hygiene and rising rates of metabolic disorders such as diabetes and metabolic syndrome also are going to influence and decrease testosterone levels.
So chronic stress and sleep deprivation are particularly impactful. There it is. Obviously that kind of goes without saying, but everything in model world is set up to have lower testosterone. Again, if you are not anal retentive or using testosterone therapy, it's nearly impossible. to fight against all these things that we are dealing with. Now let's switch gears and let us talk about the decline in IQ levels. So research indicates a global decline and IQ scores often referred to as the Flynn effect reversal.
So a study by Bratzberg and Roggeberg found that IQ scores among Norwegian men born between 1962 and 1991 have decreased. So more recent data from other countries including the UK, Denmark and Germany also suggest a downward trend in IQs scores over the past few decades. Also a 2020 study published in intelligence, the journal intelligence suggests that average IQ scores in several Western countries have dropped by about three to five points since the early 2000s. So again, this is one of those things it's like harder to get a gauge on, but even just a three-to-five point decline in IQ has massive effects on the population.
I know that sounds like a little, just like, you know, it sounds a like little that testosterone's going down, but when you compound this over time, look at a literal halving of the testosterone in the first world. You know? What is happening if the average IQ goes from 100 to 95 or even 90? Like, what does that mean for the way people behave and the people collectively interact with each other? So what's causing this? I would say testosterone, obviously, but we let's look at some of the other factors.
So obviously we have the changes in education systems, including teaching methods and curriculum may not be effectively fostering cognitive development. There's also been a shift towards standardized testing and rote learning, which may and really does not cultivate critical thinking skills. Also, we have the impact of technology. Now, technology is amazing. It allows me to make a video like this so that you can become more aware and teach yourself. So in one way, you have more access to be able to teach herself anything.
But if you look at the nature of what gets clicks and views online, You quickly see that technology does not typically bring out the best and brightest in humanity. So over-reliance on technology and digital devices may be affecting attention spans and cognitive development. The pervasive use of smartphones and social media has been linked to reduce focus and memory attention. Obviously too, people now from the time they're out of the womb have access to screens and devices.
We really have to look at how that's affecting the brain. I was at a conference back probably seven or eight years ago now and the CEO of Intuit, the technology company and software company was there. And someone asked him what they were looking at for the future in order to keep their company competitive. I always will remember this because it was such a random and weird answer that stuck out to me. You know, with a software company, you think we're like, oh, we'd be studying artificial intelligence or something like that.
Cause this was, I think 2017, 2018. And he said, We're studying the human brain development of young people under the age of 12 because they have access to devices. Their brain is developing different structurally than the. Human brain has in the past. basically saying that human brains now develop differently than they did in the past because of access to screens. And so why would the leader of a QuickBooks hacks software company be interested in studying the human brain?
Because he knew 20, 30 years from now, the brain will likely look completely different from a physical structure standpoint than it has looked for much of all of history. and you take that one step further, what does that look like in how people behave and how they interact with each other because their brains are actually different. So very key to understand that. We also have environmental factors. Increased exposure to environmental pollutants and toxins can negatively impact brain development and cognitive function.
Heavy metals, air pollution, and other contaminants are known neurotoxins that can impair cognitive abilities. Obviously, as with testosterone, there's something going on with the environment that's causing a decline in IQ. Now, let's look at how these are connected. So, from a biological standpoint, testosterone has several effects on the brain. Testosterone safeguards brain cells from damage and promotes neurogenesis. It also enhances memory, focus, problem solving skills, and overall cognitive function.
Testosteron is very, very critical, again, for men and women in those regards. Now, what does it do from our mood? Testosterone influences mood, motivation, and very key here, stress resilience. So testosterone reduces anxiety and depression while increasing motivation and energy levels. I think everyone on this planet right now, if they had less anxiety, depression and more motivation in injury levels, the world would be a better place hands down. What's going on? People have very low testosterone levels.
Hence they have anxiety and depression. Hints. They have no innovation and no energy levels again. I'm going to write the, the book that I have written is in the editing process right now. And it's gonna talk about this in depth, but, um, there's also stress resilience. So this is really huge, especially for men, women too. But, uh, testosterone helps manage our stress. This is crucial for optimal cognitive performance. If you are constantly stressed out and in a sympathetic nervous system, responses basically means your fight or flight. response in your nervous system, you're not going to be able to think critically.
You're, not gonna be, able, to solve more complex math equations, You are not, going, be to build businesses, because you are constantly stressed out. So again, testosterone has a very, very critical impact on all of these different areas of our personalities and our expression of who we are. So let's look at what this does from a society level standpoint. So we obviously have the individual impact of reduced muscle, lower testosterone equals reduced muscles mass, increased body fat,
higher risk of cardiovascular and chronic disease, a lower bone density, which could result in osteoporosis, frailty and decreased physical performance. That's obvious, right? Well, when we scale that up, to an economic and political and social and cultural level, what does that look like? Well, when you take all those things away, and you people's health away that's gonna impact their productivity. It's going to decrease productivity, so think of the cumulative loss productivity in dollar amount that we're experiencing right now because people aren't
motivated and they're stressed out and don't have any assertiveness or discipline to be able to work hard or have resilience to stress. We also have an impact on innovation. So again, it goes back to this nervous system response state. If we are stressed out all the time, how much do you think you're going to be inventing? You know, like if you take back, let's go back the primal example, if your running from a tiger, you are not going invent new tools. And testosterone helps us handle the stress so that we can get to a state where we actually can innovate things.
Obviously, increased healthcare cost healthcare is exploding right now and the economy if there's one area that's growing it's healthcare. And it is because people are so sick and inflamed and what could solve a lot of that, obviously testosterone. Obviously it relates to problem solving challenges. Uh, if you take testosterone away from people, it makes it harder to solve problems. So this is kind of like a catch 22 because we have this problem of lower testosterone, which creates a decline in cognitive function,
Which it, makes, harder for people to be able to, solve the problem, of low testosterone. I talk again about this in my book. It's hard to see what you don't see. And I know that sounds like a very trite and stupid statement, but it's true. If we can at least know what we don t know, it helps us to learn what We also have an impact on economic competitiveness.
So obviously this plays a part in like, what is going on in the world and what areas of the word become more competitive or even more friendly to people that run businesses. You know, that's something I'm looking at in my own life. And also we have the idea of genes. If men and women have lower testosterone, then they have children and then, they They're continually passing down a lower testosterone rate. And so this is a different topic for different video. But if you have women that don't have enough in utero testosterone to confer to the male that they're carrying, if they are birthing a male,
then If that gets extrapolated far enough, eventually there will be no more males left. And it's not beyond the scope of comprehension. I've actually got a book on my bookshelf back here by Dr. Shauna Swan called Countdown, where she talks about this of like, if current rates continue, we might not have a species anymore because there's going to be enough in utero testosterone to confer to continue propagating the male side of our species, which obviously we need both sides of the species. So, um, Again, I'm sounding the alarm here. So is there evidence to support this or am I just wild speculation?
So what I did in this part is I basically just went through and talked about how crucial testosterone is as it relates to certain areas. Let's look at it in terms of cognitive enhancement. A study in 2004 found that testosterone supplementation has been shown to enhance verbal and working memory in older men. Older men receiving testosterone showed significant improvements in memory tasks compared to placebo. No surprise there. 2007 study found that higher testosterone levels are associated with better attention and concentration.
So men with higher baseline testosterone perform better on tasks requiring sustained attention. Again, no surprise. They're enhancing problem solving skills. Testosterone boosts the ability to think critically and solve complex problems. Participants with high testosterone level showed superior problem-solving skills in challenging scenarios. Interesting. Let's look at learning ability. So men in undergoing testosterone therapy since 2011, they exhibited enhanced learning capacity in various cognitive tests.
They were actually able to learn better. If you take a man with testosterone, he's actually be able learn to better, which again, extrapolate that to the whole population at large. It also elevates overall cognitive function. So a 2002 study found that there was a correlation between optimal testosterone levels and higher scores on general cognitive assessments. Now, let's look at neuroprotection. Just basically brain health. A 2003 study research indicates that testosterone can help prevent neuronal death and promote cell survival in the brain.
2010 study found that testosterone mitigates oxidative stress, thereby protecting cognitive functions. 2009 study, found the testosterone's anti inflammatory properties were shown to benefit brain health and cognitive performance. 2013 study testosterone treatment was linked to increased neurogenesis in the hippocampus, a key brain area for memory. So testosterone therapy was shown to increase the amount of new cells in a hippo campus, which helps us remember things better.
It also maintains brain volume. So a 2008 study found that MRI scans showed that men with higher testosterone levels had greater brain volumes in critical cognitive regions. Again, this goes back to the idea of the structure of brain. The structure the brain is literally different when you have optimized testosterone level. It's just crazy. I mean, it's point after point. Now let's look at it again from mood motivation because obviously that has very far reaching social implications the world. So 2003 study found that men with balanced testosterone levels reported better mood and cognitive function.
2014 study testosterone was found to reduce anxiety contributing to improved cognitive performance. Obviously I mean like I talked about if you're anxious you are not going to be able to perform something that's demanding cognitively. 2011 study found that higher testosterone levels were associated with increased motivation and cognitive task engagement. Now, I want to make this clear because it's like people like, oh, well, testosterone is a panacea. No, it is not. First of all, but like again, what does it go back to?
Let's say the testosterone level is in 1987, the average is 1000, now it 600. Like what is the motivation of people today versus back then? If it correlates with testosterone, then it would be like 40 to 50% of back then. Um, again, depression. So 2013 study found that testosterone therapy significantly reduced depressive symptoms and enhanced cognitive function. I've got a video about that on my channel called testosterone saved me from depression, you can check it out. It has all of my life experience of like how testosterone was the best thing for my depression but we have all these other things that are treatments that
don't really do anything. Um, 2016 higher testosterone levels were linked to greater resilience to stress and better cognitive outcomes. So again, you take the same person and put them in this two, two equal people. Say you have a clone of yourself. You put him in two equals situations, but you give one higher, testosterone and one lower testosterone. The one with higher testosterone will respond much differently and arguably be able to use that experience for something beneficial to whereas the other person with lower testosterone may crumble under the pressure.
So it's crazy how we respond to stress based on our testosterone levels. Now let's look at just overall energy and alertness. So a 2014 study found that testosterone treatment improved energy levels and cognitive alert and men with low testosterone. It improves sleep quality. Again, sleep is so imperative and it's so impaired because of everything going on in the world. 2011 study that men receiving testosterone reported improved sleep, which correlated with better cognitive function. 2012 study found that testosterone's role in maintaining physical health indirectly benefits cognitive abilities.
So again, when we have a healthy body, we'll have the healthy mind. 2013 found testosterone improves metabolic health, which is obviously associated with enhanced cognitive performance. And the 2015 study found that testosterone therapy reduced fatigue and improved cognitive function in men with hypogonitism. So you took man with low testosterone, aka hypognitizm, and then we give them testosterone. It reduces their fatigue, which improves their mind's abilities to think. Now let's look at specific cognitive skills.
So a 2008 study found that higher testosterone levels were linked to improved performance in verbal fluency tests, which basically just your ability to communicate with spoken word. It also improves spatial abilities. And this is why men are oftentimes better with directions than women are, because they have higher testosterone levels. Men with higher Testosteron levels perform better on spatial tasks, meaning they were able to map their environment better than people with lower testosterone. It boosts executive function. So a 2012 study found that testosterone was found to improve executive functions such as planning and decision making.
Again, I think a lot of times people's stress and anxiety comes from the fact that they can't actually make decisions. They're stuck in limbo. If you have testosterone, it's a much easier to make decision. Um, it also improves mathematical ability. So 2009 study found that testosterone levels correlated with improved mathematical problem solving skills. No surprise there. And, uh, here's the cool thing because everyone's like, Oh, well, if it improves your math, you know, that's good. But what about creativity 2014 study? Found that research found a positive link between testosterone. Levels and creative cognitive performance.
I can attest to that firsthand. I make a lot of YouTube videos and I write and releasing a book soon and hopefully many more books. And I've, you know, co-authored some books in the past already. You know? So it's like, it, very connected with the ability to create. Um, let's look at hormonal balance. So obviously like our hormones dictate much of our life and 2007 study found that testosterone helps regulate estrogen, obviously because it. metabolizes into estrogen, which obviously estrogen is crucial for brain health.
2015 study found that higher testosterone levels were associated with better cortisol regulation and reduced stress. So again, if we have high cortisol, that means we're really stressed out. If we had optimized testosterone in the body, not too much testosterone, but optimized levels, it's going to help us better regulate cortisol and thereby regulate stress, 2011 study found that testosterone's influence on thyroid function positively impacts cognitive abilities. It also optimizes insulin sensitivity.
So testosterone improves insulin, sensitivity, which is linked to better cognitive performance. And a 2009 study, found the testosterone role in regulating growth hormone positively affects cognitive function. I could probably do this whole other video about. taking testosterone and replacing it with the word growth hormone and have a very similar outcome of this video. But obviously the better growth when we have in the body, the that we feel. And let's look at long-term cognitive health. So a 2017 study found that men with higher testosterone levels had a slower rate of cognitive decline as they age.
Um, 2018 study found that maintaining healthy testosterone levels can lower the risk of developing Alzheimer's obviously has something to do with our IQ. And then finally the Holy grail of longevity. So 2016 study, found the testosterone therapy has been associated with increased lifespan and better. cognitive health in older adults. So again, we look at all that, what does it mean? A better body equals a better mind equals better decision making equals, a collective reality for all of us. In summation, I just have, What are you going to do?
Now you have the ability to take this information and you can listen to it and it could sound cool. And then you could go back to your life or you do something about it. You can get your blood work done. So you get tested, you find out what your testosterone levels are and see if any of the seeming problems you're having in your can be traced back. That's it for the slides and that is the ultimate survey and connection of testosterone IQ. Hopefully that made sense to you. I know obviously I was presenting Once I have an argument here, I think the decline in testosterone is very complex.
I Think the declining IQ is Very complex, but you can see that there is a hefty correlation. And I I can't control the fact that children have screens now from the time they're born. that there's fluoride in the water. I can't control the fact that when I drink tap water, I'm getting exposed to birth control. But what I control is how healthy I treat myself or how I live my life, what my testosterone levels are, and then what do with my. So again, Uh, that's up for all of us decide only you and only I can decide for myself.
You can design for yourself. So hopefully that was helpful to you guys. Um, like I said, I'm going to be coming up with a book soon. It's called testosterone, the God molecule, man's hormonal connection to divinity. And it explores all these topics in great depth and especially as it relates to spirituality.
