What are Normal Testosterone Levels in Men?

In healthy non-obese men, aged 20-40, normal testosterone levels range from 315 to 1000 ng/dL, with an average level of 627 ng/dL.

Why Optimizing Your Testosterone is Important

Knowing the average testosterone level for your age can be useful. Once identified, it can help increase your odds of successful treatment.

Getting to optimal test levels can then help drive energy, strength, and motivation. But if low testosterone symptoms aren't managed they can alternatively lead to a frustrating experience.

The following total and free T range indicates the downwards trend as men age.

Normal testosterone levels Per Decade

  • 720 ng/dL for a man in his 30's
  • 667 ng/dL for a man in his 40's
  • 606 ng/dL for a man in his 50's
  • 562 ng/dL for a man in his 60's
  • 523 ng/dL for a man in his 70's

Average Testosterone Levels in an Unhealthy Population

Depending on the lab your doctor uses, male testosterone ranges between 250 ng/dl (8.7 nmol/L) and 850 ng/dL (29.5 nmol/L).

As you may imagine, these ranges are not set to optimal levels. They are from a cross-section of men aged 20 to 80. Many of whom may be sick or diseased, from a lifetime of unhealthy habits.

Upon receiving your blood work results, your T levels may be close or under the bottom of the range. If your doctor refuses treatment, a gentle reminder of what "optimal health" entails may be in order.

After pointing out, you have the T levels of a sick 80 year old; hopefully, your doctor will come around.

Emphasize your Low Testosterone 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 specific to 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.

Doctor being Stubborn? Up the Ante to Ensure Treatment

If all else fails (as sad as it may seem), play the desperation/victim card. Maybe tell him you're on the cusp of getting fired, due to poor work performance.

Alternatively, you could share that your wife/girlfriend has threatened to leave. Saying they're dissatisfied over your sex drive/impotence problems or recent lack of ambition.

Most doctors with a soul will come around, once you explain the seriousness of your case. And if they don't, shop around. Sooner or later you'll find a doctor who's sympathetic, as tough as that search may be.
