Testosterone Levels by Age: Whats Normal, Whats Optimal, and When to Act Testosterone Levels by Age Chart: Whats Normal and When to Be Concerned Some medications, particularly those used in hormone therapies, may lead to fluctuations in PSA levels and potentially skew test results. PSA velocity refers to the rate benefits of taking testosterone booster increase in PSA levels over time, providing insight into potential prostate issues. Monitoring PSA velocity can help detect prostate cancer at earlier stages. Normal PSA levels are generally considered to be less than 3 ng/ml, but this can vary depending on individual factors. Some men with prostate cancer may have normal PSA levels, highlighting limitations of PSA as a reliable cancer indicator. Roughly 40% of males aged 45 or older and 50% of males aged 80 or older live with hypoandrogenism, or low testosterone. Symptoms of hypoandrogenism include erectile dysfunction and low libido. In males, testosterone concentration starts at about 1.9 ng/dL at age six. In children assigned female at birth, testosterone concentration starts at about 2.4 nanograms (ng) per deciliter (dL) of blood at age six and increases to about 29.5 ng/dL by age 20.

Testosterone levels are at their peak during the late teens and slowly start to decline thereafter. High testosterone levels during these years are crucial for physical development and reproductive functions. If you have symptoms of testosterone deficiency, by all means, check your levels and consult your doctor. Treatment often involves a combination of lifestyle changes and medication. Free testosterone – that 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. Factors such as diet, lifestyle, stress levels, and sleep habits all influence testosterone levels. Chronic illness can also negatively impact During puberty, the normal range of a male’s testosterone levels could be anywhere between 300 and 1,200 ng/dL. In men, testosterone is responsible for muscle growth and the development of male sex characteristics, including body and facial hair, testes, and the penis. Regardless of whether you’re a male or female with testosterone imbalances, your doctor will work with you one-on-one to develop an individualized treatment plan. This therapy doesn’t stimulate the body to increase endogenous testosterone production. Instead, it provides exogenous testosterone to help quickly increase and maintain normal hormonal levels. TRT works best when prescribed by experienced doctors who make sure the appropriate dosage is prescribed. In this article, we’ll be discussing normal and average testosterone levels by the age of the individual. Studies find that physically active men have improved hormone levels than men who may be self-proclaimed couch potatoes. Starting in your 30s or 40s, your body’s total testosterone levels begin to change. Male testosterone levels decrease by an average of 1.6% per year, but the changes in testosterone can vary wildly with age. There is an estimated 10-40% of men who have testosterone deficiencies, and the prevalence of low testosterone significantly rises in men after 45 years old. However, laboratories may report levels down to 264 ng/dL as within the normal range. Some research also suggests that high levels of prenatal testosterone levels may be linked to autism in children. However, more research is needed to see whether prenatal testosterone affects autism later in life. 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. Take the steps towards rejuvenation with our convenient online TRT treatment.
