What Is Testosterone?

Testosterone is the main sex hormone and a kind of anabolic steroid in men. It's responsible for the major development of males — especially during puberty.

The testes are what produce testosterone. During puberty, it contributes to the creation of sex drive and protein synthesis. It also supports the development of masculine features, such as increased penis size.

what is testosterone

Testosterone is usually associated with sex drive, but it's good for other aspects of your health too! These include:

  • Bone and muscle mass growth
  • Red blood cell production
  • Sperm production
  • Mood

How Does Testosterone Work?

Everything starts in the brain — particularly the hypothalamus. This is what decides how much testosterone will be produced.

The pituitary gland receives the orderthen passes the instructions to the testicles.

how does testosterone work

Most of the testosterone is made by the testicles, but a small amount also comes from the adrenal glands.

From there, the testosterone will be secreted into the blood to be carried around the body.

Take note: Scientists are actually still not completely sure about testosterone's mechanisms (2).

One of the things they are sure about is that the effects of testosterone reach its conversion into estradiol.

Estradiol is a kind of estrogen, and it's found in small concentrations in men.

It has similar roles as testosterone. These include:

  • Sperm production
  • Testicular function
  • Bone health
  • Lipid metabolism
  • Cholesterol level regulation

But even without being converted, testosterone is useful in almost every body system.

Reproductive System

In the reproductive system, testosterone causes the penis and testicles to grow. Additionally, a steady flow of testosterone in the testicles will ensure a good supply of sperm every day.

During puberty, testosterone will also cause changes in the body. These include the deepening of the voice, the growth of muscles and body hair, and an increase in sex drive.

Central Nervous System

Testosterone is also connected to behaviors like dominance and aggression. These, in turn, give rise to competitiveness. It boosts self-confidence, too.

how does testosterone work central nervous system

Testosterone also gives men energy and the ability to concentrate.

But remember that testosterone is only one part of what influences personality and behavior. Genetic and environmental factors also play a huge part in it.

Circulatory System

Testosterone encourages the bone marrow to make red blood cells!

It's also possible that this can improve

  • Cholesterol
  • Blood pressure
  • Clot-busting ability

But more studies are needed to confirm testosterone's effectiveness in these aspects.

What Are Normal Testosterone Levels by Age and How To Determine Reduced T-Levels?

Below is the normal range of testosterone levels for males in different stages of their lives:

  • Babies: 75 to 400 ng/dL
  • Children: 7 to 130 ng/dL
  • Early teens:
    • 12 to 13 years old - 7 to 800 ng/dL
    • 15 to 16 years old - 100 to 1,200 ng/dL
  • Late teens: 300 to 1,200 ng/dL
  • Adults: 240 to 950 ng/dL
what are normal testosterone levels by age

By the time men reach their 40s, their testosterone levels drop by 1% yearly. But some don't feel the effects of low testosterone until they hit their 50s.

You can experience several symptoms when your testosterone production decreases. Among these are:

  • Low sex drive
  • Fatigue
  • Moodiness
  • Decreased muscle and bone mass
  • Increased body fat

You can consult a doctor if you want to check if you're dealing with low testosterone levels. Doctors can diagnose testosterone levels based on several factors:

  • Physical exam
  • Multiple blood tests
  • Review of symptoms
  • Medications you take
  • Medical history

Blood tests are typically taken on different mornings. This is because that's the timeframe when testosterone levels are highest. Additionally, these levels can fluctuate every day.

As for the physical exam, the doctor will examine body parts like the testicles, penis, scrotum, and breasts. Testosterone levels tend to affect these parts the most.

If your doctor decides you do have low levels, they'll determine the next steps to take.

What Causes Men's Testosterone To Fall?

Testosterone production naturally decreases as you grow older. But aside from age, other factors that can cause testosterone to fall are:

  • Injury or infection of the testes
  • Radiation treatments (like chemotherapy)
  • Substance abuse
  • Genetic conditions like Klinefelter syndrome and Kallman syndrome
  • Medications such as opiate pain relief and corticosteroids
  • Hormone disorders or pituitary gland disease
  • Obesity or severe weight loss

What Are the Benefits of Having High Testosterone Levels?

Having high (or even just good) testosterone levels has great benefits. Below are some of them:

1. Healthier Heart and Bloodstream

Testosterone increases red blood cell count through the bone marrow.

what are benefits of having high testosterone levels healthier heart

Good levels of the hormone are linked to a decrease in cardiovascular risks. In fact, a large study found that men with healthy levels of testosterone have lower chances of experiencing heart attacks and stroke.

2. Higher Sex Drive

Higher testosterone levels are connected to better sexual performance.

But if you're dealing with erectile dysfunction, this likely isn't because of ONLY low levels of testosterone. Other factors may be contributing to it too.

So, you might have to deal with those factors alongside increasing your testosterone to treat the condition.

3. Better Mood

Low levels of testosterone make a person moody. They're also more subject to fatigue.

what are benefits of having high testosterone levels better mood

But having high levels of the hormone will improve your mood and well-being and reduce irritability and fatigue!

4. Stronger Bones

Testosterone maintains bone mineral density as you grow older.

Your bones remain strong enough to support your internal organs and muscles. This helps improve athletic performance.

Having high enough levels of testosterone even increases bone density — especially in the spinal and hip bones.

But it's still unclear if it can also decrease the risk of fracture.

5. More Muscle

Testosterone increases muscle mass. In effect, it's easier to lose weight. You also get an increase in energy!

what are benefits of having high testosterone levels more muscle

But you'll most likely experience this benefit of testosterone if you also do strength training and exercise.

6. Improved Cognitive Ability

Higher levels of testosterone can reduce the risk of Alzheimer's disease. Certain aspects of cognitive ability are also improved, such as:

  • Verbal memory
  • Processing speed
  • Spatial memory
  • Mathematical reasoning

BUT BE WARNED: Abnormally high testosterone levels present problems too. Some of these problems are:

  • Low sperm count
  • Damage to the heart
  • High cholesterol
  • Hypertension
  • Fluid retention (with swelling in the legs and feet)
  • Liver disease
  • Prostate enlargement
  • Insomnia
  • Mood swings

Too much naturally occurring testosterone is rare.

Most of the time, abnormally high levels of the hormone are caused by a man taking anabolic steroids, testosterone, or other related hormones. This is typically done by male athletes and bodybuilders who want to boost their muscle mass and athletic performance quickly.

What Are Testosterone Boosters and How Do They Work?

Testosterone boosters are substances that increase testosterone. They're also called testosterone booster pills or testosterone supplements.

There are two kinds of boosters: Testosterone replacement therapy (TRT) and testosterone boosting supplements. These work differently.

what are testosterone boosters and how do they work

For instance, TRT is a medical treatment. It replaces the testosterone your body doesn't have. These should also be recommended by a doctor first before you undergo any of them.

There are several kinds of TRT:

  • Transdermal testosterone - These are patches or gels that a person applies directly to their skin.
  • Injectable testosterone - This is a solution injected into a person's buttocks every 2 to 4 weeks.
  • Oral testosterone - These are not recommended. The only approved pill is Jatenzo, which is used to treat hypogonadism.

Meanwhile, testosterone-boosting supplements boost testosterone naturally. That's because they encourage your body to produce testosterone.

They're also over-the-counter (OTC), and you don't need a doctor's prescription to buy them.

These supplements contain natural ingredients that address different things.

For instance, L-arginine widens the blood cells. This increases the blood flow, so body parts get more blood (and testosterone).

Common Ingredients Found in Testosterone Boosting Supplements

Testosterone pills have different formulas, but below are some of the common ingredients:


Ashwagandha (also known as Indian winter cherry) is an herb used as a cure-all in Ayurvedic medicine.

It acts as an adaptogen — meaning it helps your body manage stress. By doing so, it allows testosterone to do its job.

In fact, a study shows that ashwagandha extract can increase testosterone levels by up to 15% in just 8 weeks!

Because of this, a man can experience increased muscle growth and weight loss. That leads to increased strength, athletic performance, and a lower risk of injury.

They'll also get better sperm quality.


Boron is very helpful in improving your testosterone.

It helps your body metabolize your total testosterone into free testosterone. Additionally, boron can cut your estradiol levels by half!

It also improves blood flow, which can contribute to better sexual health.

Of course, boron boosts the effectiveness of vitamin D, too — another vitamin helpful to testosterone.

D-Aspartic Acid

Good testosterone booster supplements have D-aspartic acid.

This amino acid is involved in making and releasing different hormones — including testosterone.

D-aspartic acid will tell the hypothalamus to release the gonadotropin-releasing hormone. This will prompt the pituitary gland to release luteinizing hormone and follicle-stimulating hormone.

These hormones will then boost testosterone production.

However, research indicates that this amino acid has no effect on men who weight train (3). However, it may be effective in men who are inactive or have low testosterone levels.

Fenugreek Extract

Fenugreek is a medicinal plant that has been used for centuries. It's packed with vitamins and minerals like calcium, potassium, and vitamin A.

Because of this, it's great for many things — like increasing testosterone.

Fenugreek contains furostanolic saponins, which may boost testosterone levels.

Additionally, fenugreek extract can increase libido and better athletic performance.

You also get lower body fat and better muscle strength.


Magnesium is mainly concerned with supporting muscle and nerve function. It's also good for immune function and reduces the risk of hypertension.

But magnesium can increase testosterone too. Additionally, it can also improve muscle growth and physical performance.

Nettle Leaf Extract

Nettle leaf extract from the stinging nettle plant stops testosterone from converting into dihydrotestosterone. This is a more potent kind of testosterone.

However, too much of it causes problems like sleep apnea, hypertension, and enlarged prostate.

Instead, nettle leaf will increase the levels of free testosterone.

Panax Ginseng

Panax ginseng is known by many names. These include Korean Red Ginseng and Asian Ginseng.

This plant has been used to improve the immune system. It contains ginsenoside compounds that can prevent inflammation.

They can also increase cells' antioxidant capacity. Because of this, sperm quality is improved.

Panax ginseng can reportedly treat erectile dysfunction. But studies have mixed results.

Vitamin B6

Being deficient in vitamin B6 triggers the brain to increase estrogen production. So consuming a good amount of this vitamin is helpful in increasing testosterone.

Additionally, vitamin B6 lowers prolactin, which is a hormone that interferes with testosterone.

Vitamin D3

The Vitamin D sunshine vitamin regulates more than 1,000 processes in the body!

Vitamin D3 is its active form, and it's a steroid hormone that's helpful in boosting testosterone production.

Not only that — vitamin D3 increases free testosterone in the body. This means your body has more testosterone to work with since it's not being converted to estradiol.

It's possible that the testicles have vitamin D receptors, which can help in raising testosterone levels.


Zinc is part of over 100 chemical processes in the body.

Scientists are still not completely sure how zinc and testosterone are connected. But studies show they are.

A possibility is that zinc is responsible for protein and DNA production. Alongside this, the mineral contributes to the genetic material of all cells.

Zinc also regulates the secretion of prolactin — which hinders testosterone.

What Are the Side Effects of Taking Testosterone Boosters?

NATURAL testosterone boosters won't present immediate problems. After all, they're made of natural ingredients.

But it's possible for you to have allergic reactions to some ingredients, like Fenugreek.

Having too much of some ingredients can be dangerous too. Black pepper, for instance, contains piperine. A study shows how piperine can alter the blood cells to slow clotting time (4).

As such, do your research on the ingredients of your potential testosterone booster supplement! If you're still unsure, it's best to consult your doctor.

Meanwhile, TRT can be more dangerous. This is because they can permanently alter a man's natural testosterone production. In effect, their bodies will be more reliant on the medication.

Some side effects you might experience with TRT are:

  • Hair loss
  • Acne
  • Testicular atrophy
  • Infertility
  • Male breast enlargement
  • Hypertension
  • Liver damage
  • Chronic kidney disease
  • Cardiovascular diseases

You SHOULD NOT attempt TRT unless your doctor recommends it. They'll choose the right treatment for you.

The doctor will also be able to monitor the treatment and help you manage any side effects.

How To Increase Testosterone Levels Naturally

Aside from choosing the right testosterone supplement, there are more ways to boost testosterone levels naturally:

how to increase testosterone levels naturally

Useful Foods and Vitamins for Testosterone Production

One of the most natural ways to help improve testosterone production is a good diet. Below are some foods to add to your grocery list (and what testosterone-friendly nutrients they contain):

  • Leafy green vegetables - These veggies contain many micronutrients, such as magnesium. Some examples are spinach and kale.
  • Shellfish - These include oysters and clams. They're high in zinc, selenium, and omega-3 fats. All of these manage hormone health, including testosterone.
  • Fatty fish - Salmon, sardines, and trout are rich in vitamin D and zinc. Aside from fatty fish, fish oil and omega-3 supplements will work well too.
  • Avocados - Avocados have magnesium and boron. They also contain healthy fats, which are good for hormonal health too.
  • Pomegranates - Pomegranates stay true as a symbol of fertility and sexual function. They reduce oxidative stress, which affects testosterone. These fruits also help reduce stress and help maintain physical strength.
  • Vitamin D-fortified products - Some manufacturers fortify drinks with vitamin D. These are typically plant-based milk like soy and almond. But you can also find vitamin D-fortified orange juice, cereals, and other dairy products.

Manage Stress

Long-term and chronic stress floods your body with cortisol, reducing testosterone.

This can be a difficult cycle. After all, if you're stressed, your testosterone decreases. Low levels of testosterone, in turn, will add more stress to your body.

As such, it's important to manage your stress. Carve out some time every day to unwind and indulge in your hobbies.

Get Enough Sleep

Lack of sleep throws your body into chaos. This includes affecting the hormones and chemicals in the body.

Your body recharges during sleep. So testosterone increases as you sleep and decreases the longer you're awake.

Testosterone production is highest during REM sleep — the body cycles in and out of REM sleep about every 90 minutes.

To have a good night's sleep, you should ideally get five or six full sleep cycles.

Getting enough sleep means you wake up feeling well-rested. At the same time, your testosterone improves too.

Be Active

ANY kind of exercise can help increase your testosterone!

how to increase testosterone levels naturally be active

But there are some that are more helpful than others. These include weightlifting and HIIT.

However, you shouldn't overdo it. Chronic endurance exercises (anything you do for extended hours) decrease your testosterone instead.

This is because these exercises prompt higher levels of cortisol. Another reason is that the more you exercise, the more you break down your muscles.


We'll answer some frequently asked questions about testosterone boosters:

What Are the Signs of Low Testosterone in Men Over 40?

Some symptoms include fatigue, loss of muscle strength, moodiness, and weight gain. However, some men actually don't feel the effects of low levels of testosterone until they're already in their 50s.

Why Would Men Over 40 Need to Increase Testosterone Production?

Testosterone is used in different parts of the body. It lowers cardiovascular risks and maintains bone mineral density. Testosterone can even improve cognitive function! By increasing the production of testosterone, older men can maintain and improve their health. This allows them to maintain their independence too.


Testosterone pills can help older men regain their youth's energy and health.

Most of the recommended testosterone boosters have natural ingredients. Our top 3 are:

  • TestoPrime - The overall top choice, TestoPrime capsules pack a punch. They're powerful and can give you results in a matter of weeks.
  • Testo-Max - This is for those looking to increase their libido. Testo-Max is great for improving muscle health too.
  • TestoFuel- Supports weight loss. Its ingredients also make it easier for you to build muscle.

Aside from these, you can also get into the habit of sleeping well, having a good diet, and exercising. After all, these are also natural ways to increase your testosterone!
