Testosterone is an important hormone that plays a key role in men's health and vitality. Determining what constitutes a "good" testosterone level can be complex, as optimal levels vary by age and individual factors. A few key points:
- The "normal" healthy range for total testosterone in adult males is generally considered to be 250-1100 ng/dL (nanograms per deciliter). However, optimal levels tend to be toward the higher end of that spectrum.
- Levels below 300 ng/dL are typically considered low testosterone or "low T". This can cause symptoms like low energy, reduced muscle mass, erectile dysfunction, and emotional changes.
- Testosterone levels peak in most men in their late 20s to early 30s. After age 30, levels gradually decline by about 1% per year on average.
- Factors like obesity, certain medications, chronic disease, sleep deprivation, and alcohol abuse can impact testosterone levels. Lifestyle changes can often help optimize levels.
Signs that testosterone may be too high include:
- Aggressive behavior and extreme moodiness
- Severe acne
- Enlarged prostate
- Liver dysfunction
Symptoms of low T:
- Reduced libido and erectile dysfunction
- Loss of muscle mass and strength
- Increased body fat, especially belly fat
- Fatigue, low motivation and depression
- Loss of facial, body, and pubic hair
- Reduced bone density (osteoporosis risk)
When to get tested:
- If experiencing multiple symptoms of low T
- Starting at age 35-40 to establish a baseline
- Repeat testing every 5 years until notice decline
- If symptomatic, test more frequently to monitor treatment
Ideally,
testosterone levels should be in the
higher-normal range for a patient's age group to support optimal health. The table below summarizes tentative
target ranges:
|
Age Group |
Optimal Total T Level |
:--|--:
| 20-39 years old | 650-950 ng/dL |
| 40-49 years old | 550-900 ng/dL |
| 50 years old | 450-850 ng/dL |
However, optimal testosterone levels are highly individualized. It's best to test symptoms and use lab results as a guide when determining the ideal level for you.
If levels fall consistently below 500-550 ng/dL and low T symptoms are present, testosterone replacement therapy may provide benefits for some patients under the care of a knowledgeable physician. Replacement therapy options include gels, injections, pellets and occasionally supplements or medication.
Each treatment option has pros and cons to weigh with your healthcare provider.
Frequent lab testing and follow up is vital to ensure hormones are optimized and side effects are avoided.
