Testosterone Levels Chart

Testosterone Levels Chart

Testosterone levels charts provide doctors who prescribe hormone replacement therapy with a guideline of what to look for regarding Low T. These testosterone charts do not tell the whole story of who has Low T and who does not. A person who falls in the lower range of the average testosterone levels chart may require testosterone replacement therapy due to the symptoms present whereas someone who is well below what we consider low but does not have any adverse signs of Low T will not need TRT.

If that sounds confusing, do not worry, hormone specialists are trained in how to determine who is a prime candidate for testosterone therapy. While family practitioners have barely any training in assessing hormone levels, the HRT specialist focuses only on that scope of practice.

Differentiating between growth hormone deficiency, low progesterone levels, estrogen dominance, low testosterone, and other medical conditions is what a hormone specialist does every day.

At Kingsberg Medical, we know that there is more to a diagnosis of Low T than just one blood test. Does a person have enough total testosterone in his or her body, but not enough of it freely unattached for use? Are both total and free testosterone levels low? Where do growth hormone, progesterone, and estrogen levels fall into this scenario?

These are all questions that the hormone specialist must answer when determining the proper diagnosis and treatment protocol for each person.

Testosterone Levels in Men

Perhaps one of the most confusing things for men to find out is whether or not they have Low T. Every lab has its own range of what is considered “normal.” That is why a man should always turn to a hormone specialist for a diagnosis of low testosterone. The normal testosterone levels age chart may vary significantly, and what is considered normal for one lab or medical clinic may not be for another. The HRT specialist will also look at your symptoms and their severity when determining a diagnosis and treatment protocol to prescribe.

In the testosterone levels by age chart ng/dL below, you will see the age categories broken down into ten-year cycles, with listings for a free testosterone range, what is considered average for that category, and then what is also considered as an average total testosterone level for the same age.

Age

Free Testosterone Range (ng/dL)

Average Free Testosterone (ng/dL)

Average Total Testosterone (ng/dL)

25 – 34

4.85 – 19.8

35 – 44

4.46 – 18.1

This next testosterone levels chart by age focuses solely on total testosterone levels:

AGE

AVERAGE TOTAL TESTOSTERONE ng/dL

NORMAL TOTAL TESTOSTERONE ng/dL

30 – 40

219 to 1009 

600 to 675

40 – 50

201 to 993

500 to 550

50 – 60

170 to 918

400 to 450

60 +

156 to 700

300 to 350

Although you might see that a total testosterone level of 300 – 350 ng/dL is considered normal, the goal of testosterone replacement therapy is to raise this level back to between 550 and 650 ng/dL. That is when most men report the best results. Many males will suffer symptoms of Low T at these lower levels.

Testosterone Levels in Women

When it comes to a testosterone levels chart, female values are measured differently than those of men in some ways.

Bioavailable testosterone levels are determined based on whether or not a woman is using oral estrogen for either birth control or menopausal symptoms, as follows:

20 – 50 not on oral estrogen 0.8 to 10 ng/dL

20 – 50 on oral estrogen 0.8 to 4 ng/dL

The range for women over 50 has not been established.

Total testosterone levels for all women over the age of 19 is between 8 and 60 ng/dL.

Free testosterone levels for women vary by age, although the difference is slight since they have much lower levels of testosterone in their bodies to begin with, as shown in this testosterone levels chart:
