Testosterone levels naturally decline as men age, but what constitutes "low" or "healthy" testosterone can depend on a man's age. Here is an overview of healthy testosterone ranges by age group:
In young men (ages 15-39 years old):
- Normal total testosterone levels typically range from 300 to 1,000 ng/dL with an average around 679 ng/dL.
- Some sources suggest that normal, healthy levels are even higher in younger men, such as age 25.
- Free testosterone levels typically measure between 50-250 pg/mL.
Symptoms of low testosterone in younger men can include:
- Decreased muscle mass and strength
- Difficulty with sexual function - low libido, erectile dysfunction
- Increased body fat/difficulty losing weight
- Fatigue, low energy and endurance
- Loss of body/facial hair
- Decreased bone density/risk of osteoporosis
In middle-aged men (ages 40-59 years old):
- Testosterone levels begin to slowly drop after age 30, with more significant declines often seen after 50.
- Normal total testosterone ranges from 300-950 ng/dL, with an average around 631 ng/dL.
- Free testosterone typically measures 35-155 pg/mL.
Symptoms of low testosterone may intensify in middle age and men may experience:
- Difficulty achieving/maintaining erections
- Loss of muscle and strength
- Increase in body fat, especially abdominal fat
- Decreased energy and endurance
- Loss of body hair
- Decreases in bone density
- Irritability, difficulty concentrating/focusing, depression
In older men (60 years old):
- Testosterone continues to gradually decline with age, so ranges are lower.
- Normal total testosterone is between 200-700 ng/dL, with averages around
522 ng/dL.
- Free testosterone typically ranges from 30-135 pg/dL.
Symptoms of low testosterone are prominent during aging and older men may experience:
- Substantial loss of muscle and strength
- Significant gain in body fat, abdominal obesity
- Low energy, fatigue, inability to focus/concentrate
- Decreased libido and sexual function
- Osteoporosis, height loss due to thinning bones
- Loss of body hair, reduced shaving
- Sleep disturbances, increased irritability
Diagnosing Low Testosterone
If experiencing multiple symptoms of low testosterone,
it is recommended to have your testosterone levels tested. This involves a simple blood test that measures total and free testosterone levels.
- Testing should be done in the morning when testosterone levels are highest.
- Health conditions, medications, and lifestyle factors can affect testosterone, so candidly discussing your health history is important.
- Repeat testing may be needed to confirm low testosterone, as levels can fluctuate.
