Testosterone Levels by Age: A Comprehensive Guide

Every article is rigorously reviewed by medical experts to ensure accuracy. If you’ve been experiencing low testosterone symptoms, then it may be time to explore TRT. Testosterone injections are often the most popular form of TRT, and they’re pretty easy to do on your own (11). Research has shown this method of TRT is not just effective, but also ensures you administer the same dose every single time (3). "500 can be a good T level for people with a sedentary lifestyle because they don’t require tons of T," says McDevitt. "But if you’re very athletic, you’ll need more than 500 ng/dL," she says.

Healthcare professionals recognize the wide variability of laboratory ranges. The Centers for Disease Control and Prevention (CDC) also has a CDC Hormone Standardization Program to increase the accuracy of laboratory tests. We need to ensure policies and conversations what are normal testosterone levels for males based on facts, not fear. This process involves their family and is designed to provide time, support and space for shared, informed decision-making. John Harvey, M.D., M.P.H., is an Internal Medicine physician and professor of public health. His work focuses on improving healthcare quality and cost efficiency through policy-driven research.

It is important to recognize that testosterone levels fluctuate throughout the day, often peaking in the morning and declining in the evening. A single low reading may not necessarily indicate a long-term deficiency. If symptoms are present, multiple tests over different days are recommended to obtain an accurate assessment. Just like it can be too low, your testosterone can also be too high, and that’s equally problematic (8). When your testosterone levels are getting into the 1,000 up to the 1,500 ng/dL range—and staying up there—that’s too high, says McDevitt. I gave you the hormones to become an adult and to reproduce’ and they start to slow down," says McDevitt. At its peak, during your adolescent years, a normal range for your testosterone is anywhere between 300 and 1,200 ng/dL (4).

Regular PSA testing is essential for monitoring prostate health, especially as men age. Elevated PSA levels can indicate a range of issues, from benign prostatic hyperplasia (an enlarged prostate) to infections or cancer. PSA is a protein produced by the prostate gland, and its levels in the blood can provide valuable insights into the health of this walnut-sized gland. Elevated PSA levels can signal potential issues, including prostate cancer, but they can also be influenced by other factors. Obesity, lack of sleep, stress, and poor nutrition can all tank testosterone levels.

Treatment options range from lifestyle adjustments to medical interventions such as TRT. Men experiencing symptoms should consult with a healthcare professional to determine the most appropriate course of action based on individual needs and health status. While these figures serve as general references, testosterone levels can vary widely among individuals. It is important to consider symptoms, overall health, and lifestyle factors when assessing whether testosterone levels are within a healthy range. It’s essential to a man’s day-to-day health, including sex drive, sperm production, muscle growth, bone growth, hair growth, voice deepening, red blood cell production, cognition, and glucose control. Finally, testosterone is critical for maintaining energy levels and overall vitality.

However, these results are limited because the data are derived from military service members and individuals with pathological conditions such as prostate cancer. Therefore, these retrospective results might lack some degree of generalizability beyond former service members and patients with prostate cancer.

Leading a sedentary lifestyle may exacerbate testosterone declines in men as they age, according to a 2024 review published in Frontiers in Aging. But on the flip side, "regular physical activity, including strength training, has been linked to supporting healthy testosterone levels," according to Bailey. Meanwhile, some studies have found associations between low testosterone levels and symptoms like reduced cognitive function, brain fog, decreased motivation, and mood changes, according to Bailey.

Age-independent testosterone levels dropping chart studies suggest that free testosterone is a better indicator of hormonal health than total testosterone alone. Men experiencing symptoms of low testosterone should request both total and free testosterone tests for a comprehensive evaluation. Testosterone is a vital hormone responsible for numerous physiological functions in the male body. It plays a critical role in muscle mass development, bone density maintenance, red blood cell production, fat distribution, and sexual function. Beyond its physical impact, testosterone also significantly influences mood, cognitive function, and overall well-being.

That said, repeating tests may not provide much clarity if your symptoms clearly indicate a hormonal imbalance. During testosterone levels tests, a sample of blood is drawn from a vein in your arm using a tiny needle. The blood is collected in a test tube or vial that is then taken to the lab and evaluated. Finding that your testosterone levels are very low, though, doesn’t automatically mean that you need treatment. As this data takes the middle third as normal, these normal ranges may be too narrow.
