Testosterone Levels by Age: Whats Normal, Whats Optimal, and When to Act

Testosterone Levels by Age Chart: Whats Normal and When to Be Concerned

A normal testosterone level for adult men is around 8.7–29 nmol/L (250–836 ng/dL). These values don’t take your symptoms, baseline levels, or age-related decline into account. If your testosterone levels are less than 12 nmol/L and you have symptoms, you may benefit from testosterone replacement therapy (TRT).

Normal testosterone levels support sexual development, libido, healthy muscles and bones, and mood. Guidelines vary, as do factors like age or medication use, but a normal level for an adult male typically ranges between 450 and 600 nanograms (ng) per deciliter (dL). Levels at 300 ng/dL or less are considered low and above 1,000 ng/dL is high. Testosterone levels naturally vary across different ages, reflecting significant changes in a man’s life. Understanding your testosterone levels is key to managing your health as you age, as these levels can impact everything from muscle mass and libido to mood and energy levels. Males are more likely to experience symptoms from low testosterone levels, while females are more likely to have negative effects from high testosterone levels.

Though you may feel great in the short term, in truth, you’re doing more harm than good. On the other hand, free testosterone is floating around your body, ready to be recruited by your cells.

A blood test to determine your testosterone levels can help explain how you feel. Over the course of an individual’s life, their natural testosterone levels can fluctuate. Numerous different factors can influence endogenous testosterone production, including diet, lifestyle, sleep habits, stress levels, medications, and supplements. Low testosterone levels can lead to serious health problems in both women and men. At TRT Australia, we understand the importance of maintaining optimal testosterone levels for overall health and well-being. Our testosterone levels by age chart is a crucial tool for any Australian man seeking to understand his hormonal health.

Radiation therapy can be delivered externally or through radioactive seeds implanted in the prostate. “There is only little data on boys regarding PCOS-related metabolic and CVD risk, as PCOS is a female condition by definition.” The widespread decline in T levels also has implications for society as a whole, says Houman. Low testosterone is also known as “male hypogonadism” – because of the reduced production of testosterone from the testicles. Testosterone levels follow a predictable pattern over the course of life, but the rate of change can vary from person to person. But did you know that how you workout, can also boost your testosterone?

Understanding this pattern can help anticipate changes in the body and address them proactively. Aging is a common cause of lower testosterone, but there are a number of potential causes of atypical levels. Chemotherapy treatment for cancer, chronic steroid use, genetic conditions, and eating disorders are just a few of the possible causes. Upon receiving the results of your blood test, your T levels may be close or under the bottom of the range.

Free testosterone (the active form) also matters, as does the patient’s overall health picture. In the same study, researchers also found that healthy, non-obese men tended to have a testosterone normal range that was higher than men who were overweight. Other studies found a similar correlation between weight and testosterone levels. The following tables outline female and male average testosterone levels by age in chart format.

Treatment often involves a combination of lifestyle changes and medication. Free testosterone – peptides that boost testosterone which is not bound in the bloodstream to SHBG (sex hormone-binding globulin) – levels have been shown to decline faster than total testosterone. While you’re with them, a doctor may recommend blood tests to assess hormone levels, says Houman. From there, they might provide guidance on healthy lifestyle changes, such as the tips above. Or, they might suggest a treatment tailored to your specific needs, which could include health testing, hormone therapy, or dietary adjustments. 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.

For those experiencing symptoms of low testosterone, professional evaluation and appropriate interventions can help restore balance and enhance overall health. Whether through lifestyle changes, nutritional support, or medical treatments, proactive hormone health management empowers men to lead energetic and fulfilling lives well into their later years. Men in their 40s experiencing symptoms of low testosterone should consider lifestyle modifications such as regular strength training, a nutrient-rich diet, adequate sleep, and stress management. If symptoms persist, medical consultation is recommended to assess whether testosterone therapy or other interventions are necessary. Consult a healthcare provider to discuss potential benefits and risks before starting any treatment. Testosterone levels naturally vary with age due to biological processes, including hormonal changes and gradual decline in testosterone production as you grow older.

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. Low testosterone levels in women are identified as 25 ng/dL or less in those under 50 years old, and 20 ng/dL or less in those aged 50 and older. Below is a testosterone level chart by age, along with information about how testosterone therapy in Aventura can help you stay healthy as you continue to age. Thyroid hormones, including Male Excel’s desiccated thyroid, should not be used alone or in combination with other drugs to treat obesity or weight loss. In patients with normal thyroid levels, doses of Male Excel’s desiccated thyroid used daily for hormone replacement are not helpful for weight loss.
