What Are Normal Testosterone Levels By Age
The two charts below list the general normal ranges of testosterone based on age and sex. The level is measured in nanograms per deciliter .
Its important to note that the normal ranges for testosterone levels can vary based on the type of blood test done and the laboratory where it is done. Your provider will always reference your laboratorys normal ranges when interpreting your results. Talk to them if you have questions.

Emphasize Your Low Male Hormone Symptoms
Perhaps your doctor is stubborn or doesn’t like their patients being active participants in their own healthcare. In that case, you may be better off emphasizing your symptoms of low testosterone.
Noting a loss of sex drive, the development of impotence, and/or reduced muscle mass and strength is a start. That should give any knowledgeable doctor a red flag that T levels aren’t on par.
Depression, fatigue, and loss of motivation are also commonly caused by low testosterone. Sadly, many doctors would rather prescribe an antidepressant. Bringing back to normal, a natural substance your body already makes, may be wiser.
Knowing Whats Normal: Testosterone Levels
Among men, testosterone levels can vary greatly throughout life. Generally, most men reach peak levels of testosterone during puberty and then experience yearly declines with aging. Over the course of a 24-hour period, men can experience substantial rises and falls in their testosterone levels, affected by activity level, food, and sexual activity, among other things. These factors make pinpointing normal testosterone levels a complex mattermeaning testosterone level testing should be completed, assessed, and monitored by a trained and experienced physician.

Total Testosterone Vs Free Testosterone
To fully understand what is defined as normal for your testosterone levels you need to know the difference between free T and total T.
Total testosterone is simply all the testosterone you have in your body. It is produced by the Leydig cells in your testes and pushed into the bloodstream to circulate round the body.
Your muscles and organs can then access it as required.
Unfortunately two proteins, Sex Hormone Binding Globulin and albumin are also in the bloodstream and bind to the testosterone cells.
As soon as they do this the testosterone is not available for use by other body tissues.
The part which is not bound to these proteins is available to use and is known as free testosterone. It will be approximately 3% of the testosterone you produce!
Note that the albumin binding is a looser and therefore scientists have suggested it might have some slight bioavailability for cells.
What Are The Foods That Boost Testosterone
Foods that contain natural testosterone include: Oysters Eggs Walnuts Avocados Beef Flax seed Chili peppers Tomatoes Peanuts Garlic Onions Bananas Strawberries Carrots Celery Cabbage Cauliflower Cabbage Beets Spinach Whole grains Dried prunes Black coffee Dried figs Chocolate Tea Mushrooms Water Watermelon Peanut butter Grapes Salmon Sardines Watermelon Pomegranate Water Watermelon And meat Watermelon meat Water again!.

These Are The Normal Testosterone Levels By Age
Unfortunately, we dont have good results which show testosterone levels for normal people without symptoms etc. We have to rely on a combination of averages and the studies we do have looking at when patients get symptoms.
It is worth remembering that all of this is individual. If you have a low testosterone level but no symptoms then that does not mean TRT is the right choice for you. These results have been available since 1996 yet they continue to be ignored in favour of more generalised values.
The best option would be to produce lab ranges that are based on some more comprehensive studies of the average levels of men combined with the levels at which the average man gets symptoms.
These results do show a reduction in testosterone levels with age, as well as an increase in SHBG and a further reduction in average free testosterone levels with age. It also demonstrates why SHBG and free testosterone are so important for testing. You can see the
You can see that SHBG , which attaches to testosterone and makes it unable to bind to receptors in the body, rises with age.
This is one reason why a mans free testosterone drops so much with age. And its another good reason to always have free testosterone checked when worried about low testosterone symptoms.
There are several studies which show that a mans testosterone levels decrease gradually with age around 1.6% on average per year for total testosterone and 2-3% per year for free testosterone .
Symptoms Of Low Testosterone
The symptoms of low testosterone reflect the role that the hormone plays in your body. As testosterone is essential for your fertility, energy levels, and muscle and bone strength, low-T can impact these areas of your health.
You may suffer from:
- Loss of sex drive and erectile dysfunction
- Fatigue and problems sleeping
- Loss of body and facial hair
- Depression, irritability, or memory loss
If you are experiencing some of these symptoms, you can always visit your GP and ask to have your testosterone levels checked. They will consult with you about your symptoms and may recommend a blood test. Your doctor will consider whether or not your testosterone levels meet the threshold to need treatment, based on two morning fasting blood tests plus a physical assessment and symptom check.
Its worth bearing in mind that many of the symptoms above can be the result of lifestyle issues such as poor diet, lack of exercise, or smoking. Your doctor might recommend making changes here, to see if that improves your symptoms, before suggesting treatment for low testosterone. Testosterone levels can also be affected by underlying health conditions such as diabetes, liver disease, or kidney disease.

What Causes Low Testosterone
Age is a major cause of low testosterone levels, but there are other factors that can contribute to low levels of testosterone.
These include age, obesity, heart disease, diabetes, high blood pressure, and depression. Some medications can also affect testosterone levels. For example, drugs used to treat an enlarged prostate or cancer can lower testosterone levels by interfering with hormone production or making it more difficult for hormones to get into the cells where theyre needed. If you have any of these conditions, talk with your doctor about how they might affect your health before starting treatment for low testosterone.
When Should You Have Your Testosterone Level Checked
Doctors recommend that men should get their testosterone level checked when they reach 35 and every 5 years after that.
If the patient undergoes testosterone replacement therapy, however, then their levels should be closely monitored so that it doesnt get too high. Once treatments start, it becomes a balancing act. Youd have to take some precautions to make sure that you dont go over the normal testosterone range. This is part of why an experienced medical professional should be consulted if testosterone levels are outside of a normal range.
If youre having issues or symptoms with low testosterone, call the team at Premier Mens Medical Center in Orlandonow to schedule an appointment to have a consultation with their experienced and specially trained medical staff.

Do Women Need Healthy Testosterone Levels
Testosterone plays a very important role in in the female body. Women do not need as much testosterone as men. However, it still plays a critical role in their overall health and well-being.
So why is it so important for women to have healthy testosterone levels? For starters, testosterone plays a role in the health of almost all tissues in the female body. Researchers have found functional androgen receptors, or testosterone receptors in almost all tissues including the breasts, heart, blood vessels, gastrointestinal tract, lungs, brain, spinal cord, bone marrow and reproductive tissues .
Talk about a team player! Its incredible that one single hormone can maintain the health of so many different parts of the body.
Healthy testosterone levels also help to prevent metabolic disorders in women like cardiovascular disease, type 2 diabetes, or metabolic syndrome. In fact, research has shown that normal testosterone levels protect womens hearts and have a positive impact on lean body mass, glucose metabolism and blood lipid profiles .
Clinical trials have even shown that testosterone has a protective effect on breast tissues and prevents the development of dangerous breast cancers in women .
Many older women experience depressions or a decline in sexual desire because their testosterone levels are too low. In fact, a recent meta-analysis showed that women with depression do indeed display significantly different serum levels of testosterone .
How Do Testosterone Levels Change With Age
Your testosterone levels peak in your late teens, around 1719 years old. However, your levels generally stay high for the next couple of decades. Healthy young men produce about 6mg of testosterone every day.
Around the age of 30 your testosterone levels naturally begin to decline, but its a very gradual process. For most men its a decrease of only 1% per year. By the age of 70 the testosterone production of the average man is 30% below its peak. Yet its estimated that at least 75% of older men still have testosterone levels in the normal range.
Here are the results of one endocrinology study, demonstrating how testosterone levels decline in healthy men after the age of 40 :
Testosterone levels in 40s: 252916 ng/dL
Testosterone levels in 50s: 215878 ng/dL
Testosterone levels in 60s: 196859 ng/dL
Testosterone levels in 70s: 156819 ng/dL
So, you can see that older men may have lower testosterone levels than the average for men as a whole, while still being in good health overall.

How Does Testosterone Affect My Health
Testosterone has many functions in the body. It helps build muscle mass and strength, increases bone density, promotes red blood cell production, and enhances libido .

Testosterone Levels In Men By Age
It is a fact that testosterone levels in men fall as they age, often at the point in life when a man most needs to maintain a steady supply of this vital hormone. This decline typically occurs at some time after a male turns thirty, with a continued decrease of about 1 to 2 percent each year that follows.
Although such a slight reduction in the secretion of testosterone probably does not seem like much at this point, after ten years of a 2% drop every twelve months, a man could find that his production of testosterone is down 20 percent. Now that can make a tremendous adverse impact on his overall well-being quality of life.
Free testosterone that which is not bound in the bloodstream to SHBG levels have been shown to decline faster than total testosterone. A comparison of testosterone levels for males in the chart to the right displays a decrease of about 30% of total testosterone in healthy men between 25 and 75 years of age compared to 50% for free testosterone.
Testosterone And Womens Health
Women produce much less testosterone than men do, but it still plays an important role in their body functions. For example, testosterone helps regulate menstrual cycles and reproductive function.
It also promotes healthy levels of estrogen another hormone that regulates female reproduction which can help prevent osteoporosis .
In addition, testosterone may also play a role in reducing feelings of fatigue and improving cognitive function .

What Are Healthy Testosterone Levels In Each Tanner Stage
Puberty is an especially tricky period to determine healthy testosterone levels. Hormones play a large role in regulating the development of secondary sexual characteristics which emerge during this stage.
This becomes problematic because individuals reach puberty at different ages. So during this period of transition, age may not be the best basis for determining healthy testosterone levels.
This is why some doctors refer to the Tanner Staging instead of age to determine healthy levels of testosterone in young men and women. The Tanner Staging breaks down the development of secondary sex characteristics in 5 stages.
For women, the Tanner Staging is based on the development of their breasts. Here are the healthy testosterone levels according to Tanner Staging in women:
- First Stage below 7-20 ng/dl
- Second Stage below 7-47 ng/dl
- Third Stage between 17-75 ng/dl
- Fourth Stage between 20-75 ng/dl
- Fifth Stage between 12-60 ng/dl
- First Stage below 7-20 ng/dl
- Second Stage between 8-66 ng/dl
- Third Stage between 26-800 ng/dl
- Fourth Stage between 85-1,200 ng/dl
- Fifth Stage between 300-950 ng/dl
What Are Normal Testosterone Levels In Men By Age
Testosterone is measured in nanograms per deciliter .
According to the American Urological Association, a man should have a testosterone level of at least 300 ng/dL getting any result below that number is an indication that a patient has a low testosterone level.
Its expected for peak testosterone levels to arrive in a mans teenage yearsaround 18 or 19before it starts to decline.
But the human body can start producing testosterone even during infancy as its responsible for the development of the male reproductive system.
Here are the acceptable testosterone levels for men by age group.
To confirm your testosterone levels, a doctor will have to perform a blood test.
The best time to test testosterone is in the morning between 7 and 10 AM because thats when your testosterone levels are at their highest.

Why You Need Healthy Testosterone Levels For Your Age
All men need an adequate level of testosterone, as it helps control our lipids, cholesterol, and glucose, says McDevitt.
Testosterone also helps protect your bones from osteoporosis it helps keep bones strong and prevents them from erosion. Lastly, it helps protect the brain against dementia and memory loss. If your testosterone is within a good range, youre more sharp youre thinking more clearly.
As you age, hormone levels decline. You may become pre-diabetic, or see your cholesterol levels rise, says McDevitt. We tend to blame this on poor diet and lifestyle choiceswhich can definitely be a large factor.
But if youre pretty healthy, you adhere to a plant-based diet with a little protein mixed in, and youre still seeing medical conditions like pre-diabetes creep up or your thinking isnt as sharp, doctors often look at where your testosterone levels are.
I see patients often who say theyre having a hard time with emails and texts, unable to shoot off answers to simple questions with ease. Thats when we start to check your hormone levels, McDevitt says.
After 35 years old, hormone levels start to drop.
How Do These Normal Testosterone Levels Compare
There are differences in laboratory ranges and recommended ranges across the world. These depend on the population of the country, the studies used to produce the ranges and the laboratory analyser company behind the ranges used.
In the UK, the ranges differ between 6.9 27nmol/l to 10nmol/l 41nmol/l. The BSSM recommends that testosterone replacement therapy should be offered to patients with levels below 12nmol/l total testosterone or free testosterone of 0.225nmol/l and below.
They also suggest that men with a raised LH should be considered for TRT.
Some experienced doctors believe that a trial of treatment should be provided to see whether this will improve symptoms, regardless of testosterone levels.
Whilst this may be appropriate for some patients, the risk of side effects needs to be weighed up, especially if higher doses are used . There is some evidence that certain symptoms of low testosterone e.g. low mood and energy are present up to 15nmol/l. Even in these studies, the 15nmol/l level is the average significant level and therefore will exclude some men who would probably benefit from testosterone replacement therapy as individuals. There is new evidence that shows TRT is effective in men with testosterone levels up to 14nmol/l if they have prediabetes.
There is even less evidence looking at symptomatology related to free testosterone levels, despite this arguably being a better indicator of low testosterone issues.
