What Is Erectile Dysfunction?

Erectile dysfunction (‘ED‘), also known as impotence, is the persistent inability to achieve and maintain a penis adequately erect, for successful penetrative sexual intercourse.

Therefore, if you are not able to get hard enough for penetrative sex, or if you lose your erections during sex, and this is a frequent problem, you are struggling with erectile dysfunction.

ED is becoming more and more common by the day, and Truelibido estimates that approximately 20% of all men worldwide suffer from this condition.

The causes of erectile dysfunction are many and varied, but most of them have to do with lifestyle. In other words, the vast majority of erectile dysfunction is caused by an unhealthy lifestyle.

Let’s understand the details of erectile dysfunction.

World Map Erectile Dysfunction

Erectile Dysfunction Explained

The definition of erectile dysfunction is: The persistent inability to get and maintain erections sufficiently hard for successful penetrative sex.

Let’s break this down:

This definition means that ED is: 1) Problems getting an erection to start with, and (or) 2) problems keeping this erection for long enough to finish intercourse, and 3) that this problem is of a long-term nature.

Let’s dig a little deeper into this.

ED normally comes gradually. Meaning, when you start struggling with erectile dysfunction, the first sign is normally that you start losing your erections during sex.

ED difficult to maintain erections

In other words, you get erections just fine, but from time to time your erections fade during sex.

Then as the ED develops, you will typically find that this becomes more and more common: It gets increasingly challenging to maintain erections during sex.

And then as the ED gets more severe, the next step is often to start having trouble getting a full erection in the first place. 

This means that ED isn’t simply an ‘on / off’ event, but we can instead think of ED as a range from 0-100. 0 meaning never having any problems with erections, 50 meaning having trouble half of the time, and 100 meaning always having problems.

Let’s get to the last part of the definition of erectile dysfunction: What is meant by ‘persistent’ or ‘long-term’ difficulties.

Can’t keep erections during sex

You may have been unable to ‘get it up’ at certain times in your life. There can be a number of reasons for this, and we will explore these shortly.

But:

It’s normal to not get hard enough erections for sex, every now and then. Sometimes the body simply doesn’t work properly.

This happens to many of your bodily functions from time to time. You get sick every now and then, you are exhausted sometimes, sometimes you lose your voice, sometimes your back may hurt.

It’s normal.

Therefore it’s also normal to not function sexually 100% perfectly all the time. It is important to understand this because:

Sometimes the body simply doesn’t work properly

The definition of erectile dysfunction also entails that it is something that happens again and again, and that it lasts for several weeks, months, or even years. 

The condition erectile dysfunction = medium or long-term persistent difficulties, not the one-off events.

So if you couldn’t get it up last October, and also once about 2 years ago, you are not struggling with erectile dysfunction. 😊

By the way, erectile dysfunction is different from another common male sexual problem: Low sex-drive (libido). Although the two are very connected. You can learn more about sex drive here.

Before we move on, I wanted to touch upon one important aspect of erectile dysfunction.

Dealing with erectile dysfunction can be challenging. But there is one aspect of ED that makes it even more challenging: The fact that we men have a very difficult time opening up and talking about it.

the details of erectile dysfunction

We normally don’t talk to our friends about our ED, we often don’t talk to our partners about it, and we even shy away from telling our doctors about it.

We are so embarrassed to open up about our ED, that it can severely complicate our lives. We make life difficult for ourselves.🙄

I think it’s a combination of having big egos, lots of pride, and also that we are scared of anyone finding out that we don’t work like teenagers ‘downstairs’.

Speaking from experience, opening up can take a load off the shoulders. And your partner may even be grateful and appreciative for your openness.

Now that we can answer the question ‘what is erectile dysfunction’, let’s also try to understand the mechanics of how you get an erection.

the mechanics of how you get an erection

How Does A Man Get An Erection?

The penis is flaccid most of the time. But when you get ‘turned on’, your penis normally becomes erect.

But what is the process behind this? How do you get an erection?

Let’s start from the beginning:

Your penis is kept in a flaccid state because something called the smooth muscles inside your penis, are in a state of contraction.

To help you understand this, let’s think of a clenched fist:

When you clench your fist, several of the muscles in your hand contract in order to make this motion happen. When you let go of this clench, the muscles relax and are no longer contracting.

Clenched Fist

Similarly to the muscles of a clenched fist, the smooth muscles in your penis also contract to keep your penis flaccid.

These smooth muscles squeeze and clench around the blood vessels in your penis, which in turn forces almost all the blood to flow out of your penis.

The only blood that is allowed to enter your penis, is for maintenance purposes.

By the way, what makes this almost constant clench in your penis possible, is the mineral calcium.

Only when the smooth muscles in your penis stop this clenching and instead relax, is blood allowed to flow into your penis.

But how and when do these smooth muscles start to relax?

Smooth Muscles Relax To Provide Bloodlfow

This happens when you get ‘turned on’.

Which means that you have some form of sexual stimulation (sexual thought, kiss, touch, etc.).

When this happens, your brain starts producing the neurotransmitter dopamine.

This dopamine then sends a message to the blood vessels in your penis: Produce nitric oxide!

Through a chain-reaction of events, this nitric oxide causes the level of calcium to decline.

This allows the smooth muscles in your penis to relax. Now the tight clench is gone.

Now that these muscles relax, blood flows into your penis and and fills it up. When your penis is fully filled with blood, you have an erection.

Couple in bed turned on

This is a complex process involving many elements and steps, but there are three agents that are of crucial importance: Dopamine, nitric oxide and testosterone.

Dopamine kicks off the entire process of getting an erection, and is therefore paramount.

Nitric oxide is another essential part, because this is what causes your calcium levels to drop, which again opens the gates for blood to flow into your penis.

Testosterone, the primary male sex hormone, supports and controls anything sexual going on in your body. Therefore, you need adequate level of testosterone in order for the process to function properly.

Dopamine and nitric oxide also depend on testosterone in order to do their tasks properly.

Now that we understand both erectile dysfunction and how you get an erection, let’s take a look at how common erectile dysfunction is around the world.

Erectile Dysfunction Around The World

How Common Is Erectile Dysfunction World-Wide?

It may actually be more common than you think.

Doctors and researchers around the world have already done a number of surveys and studies on the prevalence of ED.

By aggregating these studies and surveys, we can get a pretty decent estimate of how common erectile dysfunction is around the world.

Although I need to say that there is one potential problem with this information:

A considerable amount of this information is in the form of self-reported surveys. Meaning, men filling out info about themselves without there being an actual test or control. This is problematic because the answers will often be subjective.

Erectile Dysfunction Survey

And also in some cases probably not honest. Meaning, some men are probably embarrassed to say ‘Yes I struggle with ED’, and instead say ‘No’.

Which means that the actual numbers may be higher than the reported numbers.

Nonetheless, we should be able to obtain some reasonably good estimates based on this information.

So what do the numbers say?

Based on these reports and studies, this is what the numbers say about the prevalence of erectile dysfunction world-wide:

  • Age group 20-29: 5-10%
  • Age group 30-39: 10-30%
  • Age group 40-49: 15-40%
  • Age group 50-59: 25-50%
  • Age group 60-69: 35-70%
  • Age group +70: 50-75%
Prevalence of erectile dysfunction world wide

What are the takeaways from these numbers?

First of all, many young men struggle with erectile dysfunction. And by young, we are talking about men in their 20’s and 30’s.

A second take-away is that erectile dysfunction is common all over the world. It seems to be more prevalent in certain countries, but it is nonetheless a condition that affects men world-wide.

A third take-away is that ED gets more and more common as we get older.

A fourth, and perhaps the key takeaway, is that about 20% of all men world-wide struggle with erectile dysfunction.

Let’s look at the implications of this:

What Percentage Erectile Dysfunction

There are approximately 8 billion people on planet earth. About half are men, which gives us 4 billion men.

20% of 4 billion men are 800 million men.

Based on this analysis, the Truelibido estimate is that there are about 800 million men worldwide who struggle with erectile dysfunction.

That is a very large number. As a comparison, there are fewer than 350 million people in the U.S.

Needless to say, this is an enormous health issue.

Now that we also have an estimate of how common erectile dysfunction is world-wide, let’s try to understand the most common factors that cause erectile dysfunction.

Map of the world

What Are The Causes Of Erectile Dysfunction?

In order for you to get an erection, your penis needs to be filled with blood.

And in order to maintain that erection, this blood needs to remain in your penis to keep it firm and hard.

The keys here are bloodflow and blood pressure.

If there is anything stopping the blood from flowing freely to and inside your penis, you will normally find it more difficult to get an erection.

And also, if the blood pressure inside your erect penis drops, the erection will normally taper off. This is often referred to as ‘venous leak’ (blood ‘leaking’ back out of the erect penis).

Therefore, ED will normally always be a result of impaired bloodflow or blood pressure.

More nitric oxide = more bloodflow = better erections

There are several factors that can directly or indirectly weaken this bloodflow, and therefore cause erectile dysfunction.

Let’s take a look at the most common ones.

Low Testosterone Production

If you produce less testosterone than you should, you are likely to struggle ‘getting it up’.

Why?

Because testosterone is the primary male sex hormone that underlies and supports anything sexual going on in your body.

Therefore, adequate levels of testosterone are essential for you to function sexually. The ability to get an erection, to produce sperm and to have a sex drive – all depend on testosterone.

Testosterone is essential to function sexually

Then what causes testosterone production to be less than optimal?

Inadequate testosterone production can be caused by a number of factors.

Some of the most common ones are: An unhealthy diet, too much stress, too little sleep, not enough sunshine, smoking, drinking, drugs, side effects of certain medications, polluted air, mental problems, and chemicals found in cosmetic and cleaning products.

Low Nitric Oxide Production

Nitric oxide is essential in order for you to get erections. It is one of the elements that you simply have to have enough of, in order to function sexually

Why?

Because it is nitiric oxide that opens the gates that allow blood to flow into your penis, fill it up and produce an erection.

Blood Vessels Erection

With inadequate production of nitric oxide, sufficient amounts of blood cannot enter your penis. And hence, you will normally not be able to get and sustain erections.

What can cause nitric oxide production to be less than ideal?

As with low testosterone production, there are many factors at play. A diet containing too much fat and sugar, and too few essential nutrients, can impair your nitric oxide production.

So can physical inactivity, smoking, drinking, drugs, air pollution, inadequate sleep and the side effects of certain medications.

Low Dopamine Production

If you produce less dopamine than you should, you are also likely to struggle with erectile dysfunction.

Dopamine Receptor Decline

This is because dopamine is the catalyst that sets off the entire process of getting an erection.

When you have a sexual thought, dopamine is produced in your brain. This in turn sends signals down your spinal cord, to the nerves in your penis.

These signals then instruct nitric oxide to open the floodgates, and let blood rush into your penis.

So if your dopamine production is low, your signals will be weak or may not arrive at all. And therefore, the entire process may suffer.

What causes your dopamine production to be sluggish?

Again, there are several factors. Some of the most common ones are: A poor diet, lack of exercise, overexposure to sexual stimulation, lack of sunshine, stress, not enough sleep, and mental problems.

Dopamine Erection

Aging

As you get older, your cells start to operate slower and divide less often than before.

And cells are in all your organs. They are everywhere. As the cells become slower, your organs also become slower.

This means your blood vessels get less good and transporting blood, you liver less good at filtering toxins, and your erectile structures less good at responding to sexual stimulation.

Your body’s ability to produce testosterone, nitric oxide and dopamine also declines.

As a result, you will normally find it more difficult to get and maintain erections as you get older. It’s just a fact of life.

Erectile dysfunction more common with age

However, the body is an amazing ‘thing’. And it is possible, with a very healthy lifestyle, to keep the body (and mind) operating at very high levels, even well into old age.

So although our abilities decline as we age, there’s still a lot we can do to stay young and healthy. 😊

If you want to learn more about this, you can read this guide.

Diabetes, High Blood Pressure, And Cardiovascular Diseases

Diabetes, high blood pressure, and cardiovascular diseases are conditions that are often linked with being out of shape and eating poorly.

Meaning, they are lifestyle diseases. They normally happen because we live unhealthy lives.

In fact, these conditions would probably not exist if we ate super healthy and exercised every day.

High Blood Pressure

Did you know that in parts of the world where people live super healthy, these conditions are almost totally absent? What does that tell you?

These conditions can cause all kinds of problems, including:

  • Damages to the blood vessels
  • Blood clots
  • Build-up of plaque inside arteries (atherosclerosis)
  • Blockage of arteries
  • Thickening of the blood
  • Insulin resistance
  • Increase of free radicals
  • Reduced production of nitric oxide
  • Reduced production of testosterone
  • Reduced production of dopamine
Cholesterol Atherosclerosis Erectile Dysfunction

All of the above are likely to reduce the free flowing of blood to and inside your penis.

And as we already know, anything that reduces this bloodflow can cause erectile dysfunction.

A note on diabetes:

Did you know that ED tends to develop 10-15 years earlier in diabetic men than in non-diabetic men?

Many men with diabetes also develop a muscle disease called myopathy.

This can cause your corpora cavernosa (those chambers inside your penis that fill will blood) to stop working properly. This can then make it difficult to obtain and maintain erections.

We have one more step of our journey to understanding erectile dysfunction.

Diabetes can cause erectile dysfunction

But before get there, let’s first quickly summarize where we are:

Erectile dysfunction is caused by poor bloodflow and poor blood pressure inside the penis.

This poor bloodflow is in turn normally caused by low production of testosterone, low production of nitric oxide, low production of dopamine, aging, high blood pressure, cardiovascular diseases or diabetes.

But what causes your dopamine or nitric oxide production to slow down? And what causes high blood pressure and these other problems?

Most of the time, these problems are caused by an unhealthy lifestyle. In other words, ultimately, it is normally an unhealthy lifestyle that is responsible for the disruptive bloodflow to your penis. Which again causes ED.

Let’s explore these factors:

Ruptured artery poor bloodflow

Unhealthy Lifestyle Factors That Can Cause Erectile Dysfunction

Too Frequent Orgasms

After having an orgasm, most men normally feel tired and out of energy. Many men just want to sleep.

And often after you have had an orgasm, it often takes time before you want sex again, right?

Well, having an orgasms is a big deal for your body and mind. It’s exhausting and takes a lot of effort.

Also, when you have an orgasm, you send off your very best of you (your sperm) to create new life.

Let’s not forget that your sperm is an unusually nutritious liquid, and it takes significant effort to keep creating this. Particularly if you ejaculate more often than what is normal frequency.

Having an orgasm is a very strenuous task for your body.

Fewer Orgasms But More Sex

In addition, you are probably not designed to do this (create life), very often. Maybe we human beings, are only really designed to have sex (or mate) a few times a year.

Let’s look at the animal kingdom. Most animals mate very infrequently, perhaps once a year. And very few species engage in recreational sex. Meaning, most species only ‘have sex’ when it’s time to procreate.

Therefore, if you have orgasms every day. Or every other day. Or very frequently, you will probably deplete and exhaust your reproductive system. It just can’t handle all the ‘sex-for-fun’.

The result of this?

You will normally find it more and more difficult to get and maintain erections. Or in other words, you are likely to start struggling with erectile dysfunction.

Pornography And Masturbation

Watching Pornography and masturbating can completely ruin your ability to function sexually.

The term is called porn-induced erectile dysfunction.

But why is pornography and masturbating so harmful?

It has more than one negative effect, but first and foremost, pornography and masturbation can numb your brain to dopamine.

Your dopamine receptors can be so overwhelmed with dopamine that they stop working.

Let’s explore this:

Porn Masturbation Erectile Dysfunction

Your brain was not designed for virtual sex. It was not designed for a never-ending supply of gorgeous sexual partners. Quite the opposite: You brain was probably designed for relatively infrequent sex.

When you watch porn and masturbate, your brain produces an extreme amount of dopamine.

And when there is a big excess of dopamine floating around your brain, the poor dopamine receptors in your brain have to work overtime to process all the dopamine.

And as they work overtime, they get tired. Then exhausted. Then numb. And if you continue, they can die.

At that point, it doesn’t really matter how much dopamine you produce. Because you can’t use it. It just floats around your brain with nowhere to go.

Let’s have a look today’s porn. Because porn in the old days (think magazines) wasn’t nearly as bad.

Watching Pornography Erectile Dysfunction

A key problem with pornography today is that it is so incredibly easy to access. You can watch porn anywhere, anytime. All you need is a smartphone or computer, and you can have virtual sex whenever you want.

Another key problem is that advances in technology has made the quality of the porn (video, audio) amazingly real. With every passing day, pornography becomes closer and closer to real life.

Now there is even virtual pornography with smart goggles and sensors, which blurs the lines between reality and imagination. At one point the distinction between real sex and fantasy will probably disappear.

Yet another problem with porn is that it offers never-ending novelty. You can have virtual sex with a new partner every 5 minutes (or every 30 seconds), you can be with a white woman, black, Asian, old, young, have a threesome, group sex, sex in public – there are no limits.

pornography offers never-ending novelty

As a result, this pornography can produce incredible sensations in you with almost no effort. In this world, you are in total control. You are king.

And this, your brain cannot handle.

It makes your brain numb.

If you watch porn and masturbate frequently, you will normally be accustomed to such extreme dopamine release, that being naked in bed with a real woman may not get you excited.

You may struggle ‘getting it up’. And you may struggle ‘keeping it up’.

This is how porn and masturbation can cause erectile dysfunction.

Man Woman Bed Erectile Dysfunction

A Poor Diet

If you don’t eat well, you are also significantly more likely to suffer from erectile dysfunction.

Because..

Every second of every day, your body needs appropriate amounts of vitamins, minerals, fatty acids and other essential nutrients, in order to function optimally.

If you don’t give your body these nutrients, what happens?

Your body has no chance to function optimally.

Let me share an example:

Hamburger Erectile Dysfunction

Let’s say your body is instructed to synthesize a certain hormone. And let’s say that this hormone needs vitamin B6 in order to be created. And let’s assume you don’t have enough vitamin B6. Then what happens?

Well, you won’t be able to manufacture that hormone.

As a result, the functions in your body that rely on this hormone, will now work slower. Or perhaps even stop working completely.

Speaking for myself, when I eat poorly, one of the first functions to stop working is my ability to get erections. I also often lose my sex-drive.

My sexual functions simply need ultra clean, high performance food in order to put up a star performance.

Unhealthy Food Erectile Dysfunction

This is also the case for many men. Probably yourself included.

Also, if you eat more calories than you burn, your blood will likely contain more glucose, triglycerides and bad cholesterol than it should.

This will thicken your blood, which will make it flow less smoothly through your veins, and can also increase your blood pressure. It is also likely to cause build-up of plaque on the inside walls of your arteries, which can develop into atherosclerosis.

Neither will help bloodflow to and inside your penis.

Regarding diet, one side of the coin is to consume healthy foods and drinks, so that you provide your body and mind with all they need.

The other side of the coin, is the damage you do to yourself by consuming unhealthy foods and drinks.

Erectile Dysfunction Bad Diet

Therefore, if you don’t provide your body and mind with all the essential nutrients they need, and you consume unhealthy foods and drinks on top of this, you hit yourself with a double whammy.

A note on sugar and salt:

Consuming too much sugar is also likely to contribute to erectile dysfunction.

If you consume more sugar (glucose) than your burn, this will float around your blood. It may make your blood thicker, increase blood pressure and cause atherosclerosis.

Excess sugar can also increase your levels of the free radical superoxide. Your antioxidants kill these free radicals. But if you have more free radicals than antioxidants, these free radicals can run rampage in your body.

Also, antioxidants protect nitric oxide from free radicals. With less antioxidants to protect your nitric oxide, your nitric oxide level is likely to drop.

Sugar Erectile Dysfunction

A high salt intake can increase your blood pressure. When you have too much salt in your blood, your kidneys struggle to filter out water from your blood.

As a result, your blood contains too much water. And hence pressure increases.

High blood pressure can damage your arteries, can cause atherosclerosis and can alter bloodflow.

Excess salt in your blood also decreases your arteries ability to produce nitric oxide.

All of the above can lead to erectile dysfunction.

Cigarette Smoking

We are supposed to breathe clean air. Not cigarette smoke, nor any kind of smoke.

Smoke contains thousands of chemicals

Smoke contains more than 7,000 chemicals, many of which can cause great harm to your body.

Smoking can reduce your nitric oxide levels, it can damage the normal release of dopamine in your brain, it can cause insulin resistance, it can blast stored fat into your bloodstream, it can increase your blood pressure, and more.

Any of these factors can lead to ED.

In fact, studies have shown that smokers are up to 40% more likely to struggle with ED than non-smokers.

If you smoke other ‘things’ than tobacco, or engage in drug abuse, the effects might be similar. In other words, this may also potentially cause erectile dysfunction.

Cigarettes can cause ED

Alcohol

Alcohol should not enter your body. At least not in large quantities. Because it is a toxin. It can therefore cause all kinds of damage.

Alcohol can damage the dopamine production in your brain. Hence, excessive consumption of alcohol can cause you to manufacture less dopamine than you should.

It can also hurt the arteries to your heart, called the coronary arteries. In fact, it can damage any and all arteries in your body. This can make it harder for your arteries to produce nitric oxide.

Consumption of alcohol can also cause plaque build-up inside your veins, called atherosclerosis.

It can also lead to an increased production of cortisol and a decreased production of testosterone.

All of the above can cause erectile dysfunction.

Beer Erectile Dysfunction

Lack Of Exercise

Exercise is one of the best actions you can take to combat erectile dysfunction. Because it can improve your bloodflow in several ways.

And the opposite, not exercising enough or simply being out of shape, will also often cause ED.

Exercise and diet have lots in common when it comes to ED. Meaning that lack of exercise causes many of the same issues as does a poor diet.

For instance, if you consume more calories than you burn (or if you are overweight), you will typically have more ‘bad stuff’ floating around in your blood.

And ‘bad stuff’ refers mostly to glucose, triglycerides and bad cholesterol. These substances thicken your blood, which makes it flow slower around your body, particularly in your very narrow arteries.

Pizza Erectile Dysfunction

In addition, thicker blood can increase your blood pressure. Which in turn can make your arteries stiffer, make them rupture, and make them less able to produce nitric oxide.

In addition, as you have more ‘bad stuff’ floating in your blood, this will normally start to get attached to the inner walls of your blood vessels. This will cause plaque build-up, which when severe, can lead to the condition called atherosclerosis.

When the inner walls of your blood vessels are covered with ‘gunk’, there is less space for blood. Hence your bloodflow suffers. But your arteries compensate by expanding, so that the same bloodflow is maintained.

Now your arteries are in a constant state of expansion. Needless to say, this is not good.

But then let’s say more ‘gunk’ gets stuck inside your blood vessels. Now they have to expand further. At some point, they cannot expand anymore. Then as ‘gunk’ builds up, your arteries may get clogged.

Atherosclerosis Erectile Dysfunction

If your arteries to or inside your penis are clogged, can you guess what happens?

Yeah, erectile dysfunction.

Also, as your arteries are covered with plaque, it will be much harder for them to produce nitric oxide.

But there is more:

If you weigh more than you should, and particularly if you have a large belly, your body will likely start converting your male sex hormone testosterone into the female sex hormone estrogen.

This will not only reduce your overall testosterone levels, but also shift your testosterone / estrogen balance so that testosterone is even less effective than before.

This can be damaging:

Big Bellly Erectile Dysfunction

Because you will now normally find it harder to maintain your muscle mass.

As your muscle mass declines, you will need less energy. Which means you will burn fewer calories.

And if you keep eating as you did before, these extra calories will be stored as fat.

And more fat means even less testosterone. And the vicious circle has started. 😳

Increased amounts of body fat also normally leads to an increase in cortisol levels.

Excess amounts of cortisol will normally reduce testosterone levels, and hence by being overweight, testosterone gets attacked by yet another front.

Hence, not exercising enough, directly slows down your bloodflow, it reduces your testosterone production and it reduces your nitric oxide production.

Fat Erectile Dysfunction

Stress

The modern human being stresses a lot more than he probably should. And stress can be one of your worst enemies to having a normal sex-life.

A little bit of stress won’t hurt you. However, it’s the long-lasting, constant stress that can wreck havoc with your ability to get erections.

But let’s start from the beginning:

Because stress is actually good. It has a very useful purpose.

It is a mechanism for dealing with a situation that is perceived as potentially dangerous, or requiring special attention.

Let’s say you’re walking down a dark alley at night and you are being followed by someone. Someone you think has bad intentions.

Dark Ally Stress

This situation will probably make you stress.

You now get a burst of energy, which will make you more alert, see clearer, hear better, and mobilize extra energy in your muscles – in case you need to run or fight.

What just happened was that your body produced cortisol, adrenaline, norepinephrine, dopamine, and other chemicals, and release them into your bloodstream.

This stress is extremely useful, as it may save your life or help you avoid harm.

But at the same time as your body channeled resources to those parts of your body that were critical (hearing, vision, muscles needed for a quick escape, etc.), it also shut down other parts of your body.

Some parts of your body that were not useful in the dangerous situation, such as your reproductive system, and your immune system.

Stress may save your life

Think about it: When your life is on the line, your reproductive system is not important. So you shut it off.

The same happens if you stress every day. Then your body essentially shuts down your reproductive system every day. And the result is higher likelihood of erectile dysfunction.

Hence: Stress once every now and then = OK. Stress every day = Not OK.

Two more items:

Excess levels of cortisol will also normally reduce testosterone levels, because cortisol and testosterone compete for the same space, meaning more of one normally means less of the other.

Also, elevated stress levels over a long period of time puts additional strain on your heart. And may eventually lead to heart disease, which in turn may lead to impaired bloodflow.

stress can lead to cardiovascular disease

Lack of Sleep

If you don’t sleep enough, you are also in the danger zone of erectile dysfunction.

Sleep is necessary for your body to recover after a day’s use. You need sleep to restore functions that have been used extensively throughout the day (muscles, hormones, etc.).

And you know the feeling of not getting enough sleep, right? You get tired, slow, sluggish and fatigued. All you really want is sleep.

You will normally be less interested in sex when you are tired, and you will also normally find it more difficult to get erections. Your body is simply less keen on sex.

However, the most important reason why lack of sleep can cause erectile dysfunction, has to do with testosterone production.

Lack Of Sleep Mobile Erectile Dysfunction

Because it is when you sleep that you produce testosterone.

So if you get 5 hours of sleep instead of 8 hours, you will produce significantly less testosterone.

And if you are sleep deprived over longer periods of time, your testosterone level is likely to be depressed.

Inadequate sleep also impacts your production of dopamine, and hence creates dopamine imbalances.

By the way, if sleep deprivation goes on for long enough, bodily functions will not only slow down, but they will shut down.

And taken to the extreme, sleep deprivation can cause premature death.

Tired Erectile Dysfunction

Lack Of Sunshine

You may not be aware that you need sunshine to be able to function optimally sexually. But you do.

Let me explain:

When sunshine lands on your skin, your skin is able to produce vitamin D3.

And why is vitamin D3 so important?

Vitamin D3 is an essential building block of testosterone. So if you don’t have enough vitamin D3, it will be impossible for your body to produce enough testosterone.

And with low testosterone levels, it will normally be very difficult for you to get and maintain erections.

Yes, you can get some vitamin D3 from foods, but it is practically impossible to get enough vitamin D3 from foods in the long run.

Sunshine uvb vitamin d3

Therefore you need the sun to fill up the balance.

What do you do if getting sunshine is impossible or impractical? For instance if you live in a place where the sun seldom shines, or if you work inside during sunshine hours.

In that case, you can also take a vitamin D3 supplement.

However, I always prefer to get nutrients the natural way, if possible.

But sunshine is not only important for testosterone production. Sunshine is a life-giving force that is essential for our bodies in several ways.

Your immune system needs sunshine to function optimally, sunshine increases serotonin levels and is necessary for you to be happy. Sunshine also reduces many diseases and cancers, increase fertility, and much more.

Psychological Factors

Psychological factors can cause imbalances in your brain. They can cause your dopamine levels to get out of whack, your serotonin production to falter, it can ramp up production of cortisol, etc.

It can also cause your testosterone production to fall.

Common psychological issues are: Anxiety, guilt, depression, low self-esteem, post-traumatic stress disorder, fear of sexual failure, indifference, etc.

Although each of these factors can impact you in a specific way, they also have something in common:

They will typically put you in a state where you are preoccupied with negative thoughts.

And these negative thoughts can occupy a significant amount of mental space.

Depression Can Lead To Erectile Dysfunction

With a mind filled with negative thoughts, you often will not have mental space for sex. It therefore simply may not interest you.

Or you may develop an unhealthy relationship to sexuality.  This can take on many forms, but it can cause imbalances.

And as a result of these negative processes taking place in your mind, you may find it difficult to get erections. And therefore suffer from erectile dysfunction.

This is not uncommon.

Research has indicated as many as 20% of all erectile dysfunction cases may be due to psychological factors.

Sad Man Erectile Dysfunction

Cycling

Significant time spent on the bike can also lead to erectile dysfunction.

But please note that biking is healthy. Only hours and hours on the bicycle seat will normally cause ED.

The reason why biking can cause ED, is because of the pressure this puts on your butt.

Or rather, the area between your anus and penis.

Sitting on the saddle for long periods of time may cause damage to the nerves and arteries in this area. And these nerves and arteries are essential in the erection process.

Therefore, if you weaken the functioning of these nerves and arteries, it may be more difficult to get erections. And a possible outcome is erectile dysfunction.

Nerve Or Spinal Cord Damage

The sensations of libido, arousal, sexual pleasure and orgasm, are all generated in your brain. Therefore, your brain is your most important sexual organ.

And in order for your brain to communicate with your penis, for instance to make it go from flaccid to erect, it sends information through your nerves and via your blood stream.

But what happens if the information highways get damaged?

Well, the information may not arrive. Or arrive in a distorted format.

For instance, an injury to the back causing spinal cord damage, or a damaged prostate as a result of prostate surgery, can damage this information nerve system.

This may make it more difficult, or impossible, to get erections. Hence this can also lead to ED.

Side Effects From Medications

Many common medications can cause erectile dysfunction as a side effect.

Let’s look at some of the most common ones.

Medications for depression and anxiety can cause ED. Very often these kinds of medication are SSRIs (selective serotonin reuptake inhibitors).

These SSRI drugs interfere with your natural level of the neurotransmitter serotonin. However, studies have shown that this can also change your production and uptake of both dopamine and testosterone.

And as we know, low levels of dopamine and testosterone can cause erectile dysfunction.

It has also been demonstrated that side effects from SSRI drugs can last for years.

Medication Erectile Dysfunction

Another class of medication that often causes ED as a side-effect, are high blood-pressure drugs. Particularly beta blockers and diuretics.

Beta blockers interfere with your nervous system, and sometimes also affect the signalling that instructs your penis to fill with blood.

Diuretics can reduce the bloodflow to your penis, and hence can make it difficult to get erections.

Other types of medications that also often cause ED as a side effect are: Antihistamines, non-steroidal anti-inflammatory drugs, Parkinson’s disease medications, antiarrythmics, histamine H2-receptor antagonists, muscle relaxants, prostate cancer medications, chemotherapy drugs and hair loss drugs.

Genetics

Some men are genetically more likely to suffer from erectile dysfunction than other men.

Genetics Erectile Dysfunction

It has been discovered that variations in a specific place in the genome near the SIM1 gene, have a high correlation with an increased risk of erectile dysfunction.

One research study indicated that this was associated with a 26% increased risk of erectile dysfunction.

However, very little research has been done on this to date. Hence, we should wait for more studies before we draw firm conclusions.

Venous Leak

An erection takes place when blood flows into the penis and it fills the penis completely.

Venous leak describes the situation where the blood is not being retained in the penis, but rather quickly flows back out of the penis.

Venous Leak Erectile Dysfunction

Therefore, even if there is adequate bloodflow to the penis, you are not able to maintain an erection because the blood flows out and away.

Venous leak is not a cause of ED, it’s rather one form of ED. It can be caused by low nitric oxide production. Meaning, you produce enough nitric oxide to get an erection, but not enough to maintain the erection for long.

How To Overcome Erectile Dysfunction

If you are struggling with erectile dysfunction, there are steps you can take to recover. Most ED is a result of an unhealthy lifestyle. Therefore, this can in many cases be resolved by starting to live super healthy.

If you want to learn how to overcome your ED naturally and permanently, I would encourage you to read this guide.
