Testosterone levels can vary in men by age and physical condition. This hormone impacts a man’s life in many ways, including how much energy they have and what kind of behavior they exhibit. Having high or low levels can cause many unpleasant issues, which is why it’s important to know what is considered to be normal testosterone levels in men.

Early Years

Testosterone is present from before birth. In fact, it helps develop the reproductive system and the brain. If it’s too high, research suggests it may lead to autism. If it’s low, it may increase your chances of developing Alzheimer’s disease in the future.

Testosterone levels in men are highest from adolescence, beginning at puberty, to the early years of adulthood. At this stage, the hormone impacts the ways a male’s physical appearance changes.

According to a report by the Mayo Clinic, testosterone levels considered to be normal in male babies up to five months range between 75-400 ng/dL. These levels continue to increase at a normal rate of 100-1200 ng/dL at 15-16 years. The average adult male up to age 30 will be somewhere between 270-1070 ng/dL. to be considered normal.

Adult Males

Testosterone levels in men begin to decline naturally after age 30. It doesn’t mean anything is wrong with the man; it’s just a natural part of the aging process. However, this decline in the hormone doesn’t mean it should impact the health of the man.

While it’s natural for men to see their testosterone levels drop, the decrease should be so insignificant that it isn’t noticeable. According to the report by the Mayo Clinic, the rate of decline is about one percent or less each year. What this means is a man shouldn’t feel any different with the changes. A healthy male should continue to have adequate testosterone levels for optimal physical and sexual health for much of his adult life.

Results of Changes

Low testosterone levels in men can impact the person’s life in many ways. Besides inhibiting sexual performance, it can lead to other health problems. Signs that low levels are having a negative impact include:

  • Increased body fat with reduced muscle tone
  • Decreased bone density
  • Emotional changes
  • Alterations in sleep patterns

Because of the wide range in what’s considered normal, a person must consult with a doctor if they are concerned about their health, rather than just relying on numbers. For most men, it isn’t about the actual level, but how much it has declined from previous readings. While anything between the 270 and 1070 range could technically be considered normal, a large drop in numbers can indicate a health problem even if it still falls under the category of normal.

Testosterone plays a key role in men’s lives, which is why it’s important to monitor the levels as men get older. Normal testosterone levels in men help ensure they are in good health and able to enjoy life to the fullest no matter their age.
