Normal Testosterone Levels by Age

Testosterone Levels by Age Chart: What is Normal?

Having the test done late in the day may show that your testosterone level is lower than it really is. This is because testosterone levels tend to be highest at that time. But you may need to have this test more than once, and at different times of the day, to confirm low testosterone levels. This is because your testosterone level can change from morning to evening and from day to day. Testosterone Replacement Therapy (TRT) can profoundly impact men’s physical and mental health. Key areas of interest include expected transformations before and after therapy, understanding contraindications, the importance of monitoring free testosterone levels, and achieving ideal testosterone levels during treatment.

By addressing hormonal imbalances, we empower men to live life to the fullest and regain the energy and enthusiasm that may have diminished over time.

Note that it has completely different ‘average’ testosterone levels from what happens if you refrigerate testosterone cypionate we see in other studies. The red and blue areas combine to produce the range of ‘normal’ testosterone levels. It’s important to note that TRT is not a cure for low testosterone. Rather, it is a long-term treatment that requires ongoing monitoring and adjustment by a healthcare provider. TRT may also have side effects, such as acne, breast enlargement, sleep apnea, and an increased risk of blood clots and prostate cancer.

As a result of falling testosterone levels, you’d expect more men to be diagnosed with low testosterone. But in fact, the rates of men being treated for this condition have increased but are not in line with the drop we see in overall levels. We have a complete guide on how to increase free testosterone levels that is worth checking out. Eating a nutritious diet, losing weight, reducing stress, getting good sleep, and practicing strength training are some of the ways to counteract the signs of low testosterone and fight against the nasty symptoms described above. Testosterone helps regulate body fat distribution, and low testosterone levels can lead to an increase in body fat, particularly in the abdominal area. Men with low testosterone levels may feel fatigued, lack motivation, and experience decreased energy levels.

The most reliable method for measuring testosterone levels is through laboratory blood testing, which assesses both free testosterone (biologically active) and total testosterone in the bloodstream. These comprehensive tests require a healthcare professional’s interpretation, as normal ranges vary by age. Healthcare professionals must also evaluate results alongside symptoms and medical history. According to the Endocrine Society, men over 50 years of age who have total testosterone levels of 200 ng/dL or lower are hypogonad; they require an evaluation of pituitary function before beginning testosterone therapy. Men with testosterone levels between 200 and 400 ng/dL are borderline and should have additional testing before considering therapy, and men with levels above 400 ng/dL don’t need further tests or therapy.

They involve injecting testosterone directly into the muscle, typically every one to two weeks. This method allows for a controlled release of hormones and provides a stable level of testosterone in the bloodstream. It is possible for a woman to have low testosterone in which TRT Therapy may be used in much smaller doses compared to men. Men experiencing low testosterone may benefit significantly from TRT. This therapy helps in improving energy levels, increasing muscle mass, and enhancing sexual performance. Common forms of administration are injections, gels, patches, and pellets. If your results indicate low testosterone, your provider will discuss possible causes, such as aging, hypogonadism, or underlying medical conditions.

When you’re entering your mid-thirties, you’ll start to see it declining by at least one percent per year. High levels of testosterone in female infants may lead to enlargement of their clitoris that can look almost like a penis. It can also lead to precocious (early) puberty, which is when puberty begins before the age of eight. Healthcare providers use synthetic testosterone to treat and manage various medical conditions. Causes include testicular failure due to genetic errors, mumps, severe trauma, alcoholism, and cancer chemotherapy and radiation. In other cases, the problem originates in the pituitary gland of the brain; causes include tumors (almost all benign), head trauma, brain surgery, various medications, some hereditary disorders, severe malnutrition, and chronic illnesses.

High or low T levels in women may indicate an underlying medical condition, such as hirsutism, PCOS, tumors, or CAH. To prepare for a testosterone test, a healthcare provider may recommend fasting for several hours before getting the blood sample.

In each wave, the researchers took blood samples and conducted extensive interviews, Travison said. Participants were asked about demographic and lifestyle characteristics, self-assessed general health, smoking and alcohol habits, BMI, waist-hip ratio, physical activity and other factors. This information comes from a long-term prospective study that evaluated changes in serum testosterone on a population-wide basis. Between the ages of 17 and 18, males have between 300 to 1,200 ng/dL of testosterone, while females have between 20 to 75 ng/dL of testosterone. In some instances, insurance may fully or partially cover the costs of in-person or at-home testosterone testing. An individual can speak with their insurance provider to determine if testosterone testing is covered in their health plan.
