Overview of Average Testosterone Decline in Men by Age

The Average Testosterone Decline in Men by Age Chart is evidence of the importance of understanding your testosterone levels. What is testosterone? Testosterone is a hormone produced by the testicles in men and plays a key role in many of the physical and behavioral traits that are characteristic of males. Normal testosterone levels in men range from about 300 to 1,000 nanograms per deciliter (ng/dL). Testosterone levels can be affected by a variety of factors, including age, diet, exercise, and medical conditions.

Testosterone levels typically peak during adolescence and early adulthood and then gradually decline with age. Some men may experience a more rapid decline in testosterone levels as they age, which can result in a condition known as hypogonadism. Symptoms of hypogonadism can include low sex drive, fatigue, mood changes, and decreased muscle mass and bone density.

There are several tests that can be used to measure testosterone levels, including blood tests, saliva tests, and skin patches. If a man has low testosterone levels, a healthcare provider may recommend testosterone replacement therapy to help restore normal levels.

If you would like one of our medical professionals to give you an overview of your testosterone levels, you can order the DirectLabs Blood Panel from our affiliate US-based blood testing partner. They will create a medical order for a blood test with Quest Diagnostic Labs. Click on the DirectLabs Blood Testing link here and order the Anti-Aging Panel for your gender.

It is important to note that testosterone levels can vary from person to person and can be affected by many factors. It is important to talk to a healthcare provider about any concerns about testosterone levels or symptoms that may be related to testosterone.

The Role of Testosterone in the Body

Testosterone is a male sex hormone produced primarily by the testicles in men. It plays a crucial role in the development of male characteristics, including muscle mass, body hair, and a deep voice. Testosterone also plays a role in the maintenance of bone density, sperm production, sex drive, and male confidence.

In addition to its role in male development and reproductive function, testosterone also has important effects on other body systems. For example, it plays a role in the regulation of metabolism, bone density, and cognitive function. Some researchers have associated low testosterone with obesity and type 2 diabetes.

While testosterone is primarily associated with men, it is also produced in smaller amounts by the ovaries in women. In both men and women, testosterone levels typically peak in the late teenage years and early 20s, and then gradually decline with age.See our Average Testosterone by Age Chart Below.

It’s important to maintain normal testosterone levels for overall health and well-being. Low testosterone, or hypogonadism, can cause a range of symptoms, including low sex drive, fatigue, and decreased muscle mass. On the other hand, high testosterone levels, or hypergonadism, can cause symptoms such as acne, aggression, and fertility problems.

Recommended Dose of Testosterone Injections - It Varies by Individual

The recommended dose of injectable testosterone for men depends on a variety of factors, including the patient’s age, overall health, and the specific form of testosterone used. In general, the goal of testosterone replacement therapy is to restore testosterone levels to the normal range for a man’s age.

Injectable testosterone is usually administered in the form of an oil-based solution that is injected into a muscle. The recommended starting dose for injectable testosterone is typically in the range of 50 to 400 mg every two to four weeks, depending on the specific product being used and the individual patient’s needs.

It’s important to note that testosterone replacement therapy should be individualized and carefully monitored by a healthcare provider. The appropriate dose may vary depending on the patient’s specific needs and should be determined by periodic blood tests to measure testosterone levels. It’s also important to follow your healthcare provider’s instructions and have regular follow-up visits to ensure that the therapy is effective and safe.

Average Testosterone Decline Levels by Age Chart

As we age our hormones gradually decline. In some individuals, the rate of decline may come sooner than in others, and this may impact their well-being. Most individuals on testosterone replacement therapy usually begin seeking medical attention in their late thirties or early forties. The chart below offers a representation of hormone decline in men, while a table lists the per-decade decline in actual numerical values.

Average Testosterone Decline in Men Chart Levels Age 20 thru Age 90

It is important to note that testosterone levels can vary widely from person to person and can be affected by many factors. The following are approximate average testosterone levels for men at various ages:

  • Age 20: 300-1,000 ng/dL
  • Age 30: 300-1,000 ng/dL
  • Age 40: 240-950 ng/dL
  • Age 50: 200-900 ng/dL
  • Age 60: 170-840 ng/dL
  • Age 70: 140-800 ng/dL
  • Age 80: 120-750 ng/dL
  • Age 90: 100-700 ng/dL

It is important to note that these are approximate averages and that testosterone levels can vary significantly from one individual to another. It is also important to note that these values may not apply to all individuals and that it is important to discuss any concerns about testosterone levels with a healthcare provider.

It should be noted that due to environmental circumstances such as smoking, alcohol, and poor diet, many 40-year-olds have testosterone levels in the 200-300 levels. Possibly less than their grandfathers and certainly less than their great-grandfathers. Within a couple of generations, the modern lifestyle has done significant damage to the well-being of both men and women. 

What should I do if I believe I have Low testosterone?

If you believe you have low testosterone, it is important to speak with a healthcare provider. Low testosterone, or hypogonadism, can cause a range of symptoms, including low sex drive, fatigue, mood changes, and decreased muscle mass and bone density. Someone from our medical team can discuss options for you to get evaluated

In general, a healthcare provider will order comprehensive blood testing and then schedule an in-person examination to discuss the results of your tests.

At our clinics, if your testosterone levels are low, we will most likely recommend testosterone replacement therapy. This can be in the form of a cream, injection, or pellet implant. Testosterone replacement therapy can help restore normal testosterone levels and alleviate symptoms of hypogonadism. Over weeks and months, you will likely feel more energy and will gradually see your body composition improve. 

As with any hormone treatment program, it is important to follow your medical provider’s recommendations for testosterone replacement therapy and to discuss any concerns or questions you may have about the treatment. It is also important to follow up with your labs and medical consults regularly to monitor your testosterone levels and ensure that the treatment is working effectively.

What are the Symptoms of Low Testosterone in Men?

Symptoms of low testosterone in men may include:

  • Low sex drive
  • Erectile dysfunction
  • Decreased muscle mass and strength
  • Fatigue
  • Mood changes, such as irritability or depression
  • Decreased bone density, which can increase the risk of osteoporosis
  • Difficulty with concentration and memory
  • Decreased body hair and changes in body shape
  • Hot flashes or night sweats

Females Require Testosterone and Experience Decline with Age

Females also have some level of testosterone circulating in the body. And depending on health, they can be impacted as well by low testosterone.  In females, testosterone is produced in small amounts by the ovaries The normal range for testosterone levels in women is typically much lower than that for men, with levels typically ranging from about 15 to 70 nanograms per deciliter (ng/dL). Testosterone levels in women tend to be highest in the 20s and 30s and gradually decline with age. The following are approximate average testosterone levels for women of various ages:

  • Age 20: 15-70 ng/dL
  • Age 30: 15-70 ng/dL
  • Age 40: 10-60 ng/dL
  • Age 50: 10-60 ng/dL
  • Age 60: 10-50 ng/dL
  • Age 70: 10-50 ng/dL
  • Age 80: 10-50 ng/dL
  • Age 90: 10-50 ng/dL

It is important to note that these are approximate averages and that testosterone levels can vary significantly from one individual to another. It is also important to note that these values may not apply to all individuals and that it is important to discuss any concerns about testosterone levels with a healthcare provider.

In most cases, women should only seek testosterone replacement if they are feeling as if they are low in testosterone or other hormones. This can be tested with a simple, but comprehensive blood test. 

Average Decline in Testosterone Levels in Younger Males

The average decline in testosterone in younger males is declining more rapidly than in prior generations. 

According to a study presented at the 2020 American Urological Association Virtual Experience, testosterone levels declined in adolescent and young adult men (AYA) between 1999 and 2016. It’s believed that the overall decline in male testosterone levels may be due to various factors, including overweight & obesity, an aging population with older males exhibiting lower testosterone levels, an increase in comorbidities such as diabetes, and age-related decline.
Testosterone deficiency is prevalent among adult males, with a prevalence of 10% – 40%, and 20% among men aged 15-39 years. They analyzed serum testosterone level changes over time in 4,045 males using three different assays during the study periods. Total testosterone was found to be lower among men in the later (2011-2016) versus earlier (1999-2000) cycles.

Elevated BMI was associated with reduced total testosterone levels, even among men with normal BMI, and potential causes for the decline in testosterone levels could be increased obesity/BMI, assay variations, diet/phytoestrogens, declined exercise and physical activity, fat percentage, marijuana use, and environmental toxins.

This decline in testosterone levels in men is worrisome. Lower values of testosterone have been associated with increased comorbidities, an increased risk for all-cause mortality, and a lower libido, leading to an increased risk for erectile dysfunction. Additionally, many men in this age group may feel stigmatized and less likely to seek care for these issues. Testosterone levels in younger men are used as the benchmark normal levels for testosterone, which may lead to the undertreatment of testosterone deficiency, with severe consequences.

What are the Symptoms ot Low Testosterone in Women?

Symptoms of low testosterone in women may include:

  • Low sex drive
  • Difficulty with sexual arousal
  • Decreased muscle mass and strength
  • Fatigue
  • Mood changes, such as irritability or depression
  • Hot flashes or night sweats
  • Decreased bone density, which can increase the risk of osteoporosis
  • Difficulty with concentration and memory
  • Vaginal dryness

Free Testosterone Decline by Age in Men

One of the most important indicators reviewed by anti-aging and age management doctors when evaluating men for testosterone replacement therapy. Although normal testosterone levels may seem okay, they may not tell the whole story. Free testosterone is your available testosterone which actually does the heavy lifting for you. We will speak more about free testosterone in a moment. First, let’s look at the free testosterone levels in men as they decline with age. 

 

The average free testosterone levels in men can vary based on several factors such as age, genetics, health status, and lifestyle. However, here are the typical ranges of free testosterone levels by age in men:

  • Age 20-29: 5.7-28.0 ng/dL
  • Age 30-39: 5.5-19.0 ng/dL
  • Age 40-49: 4.5-16.0 ng/dL
  • Age 50-59: 4.2-15.0 ng/dL

It’s worth noting that these ranges are just estimates and may vary slightly depending on the laboratory performing the test. Additionally, individual results may vary depending on a person’s health status, genetics, and other factors. If you’re concerned about your testosterone levels, it’s important to speak with a healthcare professional who can evaluate your specific situation.

It’s worth noting again that testosterone is a hormone that is produced primarily in the testicles in men. It is responsible for the development of male sex organs, secondary sex characteristics, and sex drive. Testosterone circulates in the bloodstream in two forms: bound and free.

Bound testosterone is attached to proteins in the blood, primarily sex hormone-binding globulin (SHBG) and albumin. Bound testosterone is unable to enter cells and is considered inactive.

Free testosterone, on the other hand, is testosterone that is not bound to proteins in the blood and is considered bioavailable. It can enter cells and bind to androgen receptors, where it exerts its biological effects. Free testosterone represents only a small fraction of total testosterone levels in the blood.

So it is important to measure both free and total testosterone.
