What Are Normal Testosterone Levels by Age?

Testosterone Levels

Maintaining normal testosterone levels is crucial to good health for men and women.

There are no set parameters for normal testosterone levels by age – every lab has its own reference chart. This may seem confusing, but blood test results are not the only predicting factor for Low T. Even if testosterone levels are very low, if no symptoms are affecting one’s life, then no treatment is necessary. In most cases, the body will adjust to changing hormone levels. A person may also find that symptoms of Low T occur even when testosterone levels fall within normal limitations. In this case, testosterone replacement therapy can be beneficial.

It is also necessary to determine if low testosterone levels are due to aging or other factors, which the blood tests will show. We will send you to a local lab to have a sample of blood collected for analysis.

Our doctors at Greenberg Health run blood tests to find out where your numbers fall in the testosterone levels chart below:

Age Normal Total Testosterone Average Total Testosterone Normal Free Testosterone
Men 30 – 39 219 – 1009 ng/dL 600 – 675 ng/dL 4.65 – 19.0 pg/mL
Men 40 – 49 201 – 993 ng/dL 500 – 550 ng/dL 4.26 – 17.1 pg/mL
Men 50 – 59 170 – 918 ng/dL 400 – 450 ng/dL 3.87 – 15.6 pg/mL
Men 60 + 156 – 700 ng/dL 300 – 350 ng/dL 3.47 – 13.9 pg/mL

In the normal total testosterone levels above, we have taken the lowest end of the scale from among the many labs and medical centers that provide their ranges and extended that to the high end of the numbers from these charts.

What you see in the average total testosterone column is what to expect at those ages, although those numbers are far from ideal, as you will see in the next section.

Women’s total testosterone levels can go as low as 8 ng/dL and as high as 95 ng/dL to be considered normal. Since some of the charts show the low end to be 15 or 30 ng/dL, you can see the discrepancy, and know why doctors also look at symptoms when determining Low T.

For free testosterone levels in women under 50 years of age, the level is over 1.5 pg/mL, and for those over 50, it is 1.0 pg/mL.

Testosterone Levels and Aging – What to Expect

Judging from the chart above, a 45-year-old man would be marked deficient if his total testosterone level went below 201 ng/dL. If you compare it to the average at that age, it is well below the 500 to 550 ng/dL. It is not surprising then that someone with testosterone levels so low would be suffering from a variety of symptoms of low testosterone levels.

But what about the man who has normal testosterone levels of 350 ng/dL at the same age. The chart says he should be fine, right?

Wrong, if you take a look at the chart below, you will see that the ideal total testosterone level for a man of 45 is between 606 and 668 ng/dL. That is certainly quite a difference. It should not be a shock that the man with readings of 350 ng/dL is already feeling the effects of Low T even though he is nowhere near “old.”

Age Ideal Total Testosterone Average Free Testosterone
Men 30 – 39 617 – 668 ng/dL 11.8 – 12.84 pg/mL
Men 40 – 49 606 – 668 ng/dL 11.1 – 12.42 pg/mL
Men 50 – 59 562 – 606 ng/dL 10.5 – 11.38 pg/mL
Men 60 + 524 – 562 ng/dL 9.4 – 10.71 pg/mL

That is why doctors look to raise average testosterone levels up to 550 ng/dL when using testosterone replacement therapy. That is the magic number that seems to bring the best results.

How to Raise Testosterone Levels

Of course, if you are hovering just below the ideal range for your age, and only just starting to notice some of the symptoms of Low T, you may want to try some dietary and lifestyle changes to increase your testosterone levels naturally. You can use vitamins and herbs to help improve testosterone production.
