Testosterone and Age

The average man should have levels of at least 300 ng/dL. Anything outside of that is abnormal and lower numbers indicate testosterone deficiency. Some signs to​​ look for when it comes to low testosterone include low energy levels, depression, moodiness, low sex drive, and even difficulty with concentration and memory. Some cases of low testosterone have been linked to serious health conditions so it’s best to monitor your symptoms and consult your healthcare provider for any concerns. 

Testosterone levels can be related to other medical conditions and Lowcountry Male has multiple tools to get to the bottom of the issue. To learn more about the link between testosterone and diabetes, read our blog.

When it comes to age and specific levels of testosterone, it’s broken into four categories: children (infant-age 11), early teens (age 12-16), late teens (age 17-18), and adults (age 19 and up), however, some charts break this down even further. 


By age 16, levels should be between 100-1,200 ng/dL. This should gradually increase in the late teens to between 800 and 1,200 ng/dL. At the time of puberty, testosterone levels in teenage boys increase by 30 times in some cases. Mood and behavioral changes are associated with fluctuating levels and can result in aggression and increased risk taking behavior. Upon reaching an equilibrium, the body will be able to regulate emotions, behaviors, and attitudes accordingly.

Early Adulthood

Once you reach adulthood, your testosterone levels should fall between 240 and 950 ng/dL. Normally, men reach their peak testosterone levels at the age of 20. Following that, testosterone levels gradually decline over the course of the later years of life.

Older Adults

By the late stages of your life, you will notice a dramatic decline in testosterone levels. On the other hand, if the levels fall below the threshold of normal, you may be experiencing andropause. Andropause is the male equivalent of menopause, in which your body begins to produce low levels of testosterone. As with adolescents, you will likely experience mood and behavioral changes. 

By examining your testosterone levels by age, you will be able to identify whether they are too high or too low and develop a plan to correct the situation. In order to understand how to increase or balance your hormone levels, we should briefly discuss some of the factors that may contribute to low testosterone levels.

Factors That Lower Testosterone

In addition to age, weight, sleep, and diet, many other factors contribute to testosterone deficiency. The most significant of these factors is gland dysfunction and underlying disease. In certain areas such as diabetes and cardiovascular health, low testosterone levels can have an impact on the function of these systems. In addition, certain foods can lower testosterone levels, including sugar, bread, and pastries. When these foods are consumed in excess, the relationship between low testosterone and weight gain comes full circle since these foods can contribute to weight gain. 

Symptoms of low testosterone levels are present at various stages of life, including during fetal development, puberty, and in adulthood. When you reach puberty, low testosterone can manifest itself as stunted muscle growth, short limbs, reduced body hair, and even enlarged breasts (gynecomastia).

Symptoms to look out for in adulthood include low energy levels, hair loss, loss of bone mass, infertility, and erectile dysfunction. Fatigue and mental fogginess are key indicators of low testosterone levels in adult men, so if you’re experiencing any of the above mentioned, you should speak with a healthcare professional.

How to Balance Testosterone Levels

After you have addressed the symptoms of low testosterone levels, you can begin balancing them. You can balance your testosterone levels in a variety of ways, including weight loss, supplements, and hormone therapy. Weight gain is a common sign of hormonal imbalance, but most men can lose between 20 and 30% of their body weight when they increase and balance their levels.

When testosterone levels are abnormally low, it’s hormone therapy is recommended. Whether you administer the therapy through injections, patches, or pellets, it will increase your overall bodily performance. Lowcountry Male offers a variety of treatment options and with the care our medical spa professionals provide, you’re able to avoid any unwanted side effects.

With hormone therapy, you must administer it precisely to prevent unwanted side effects.

You should ensure the accuracy and purity of the supplements you purchase by choosing companies that are reputable.
