Testosterone Test: Free & SHBG, High vs Low vs. Normal Levels

What Is A Normal Testosterone Level For Your Age?

However, there’s no official consensus on healthy testosterone over the counter supplement levels. According to the American Urological Association (AUA), healthy male testosterone levels range between 450 and 600 ng/dL, and low testosterone is below 300 ng/dL. The two charts below list the general normal ranges of testosterone based on age and sex. Testosterone is a hormone that your gonads (testicles or ovaries) mainly produce. If testosterone levels are too high or too low, it can cause certain symptoms.

First, fasting morning serum samples obtained from 100 men from each of the four cohorts, in which testosterone levels had previously been assayed locally, were transported to the central laboratory at the CDC. These 100 men with previous assay results from the local laboratory were chosen at random to approximate the distribution of age and other factors within each of the four cohorts. These normalizing equations were applied to all testosterone levels measured in each of the four cohorts to generate harmonized values. These harmonized measurements were in turn used to derive standardized, age-specific reference ranges in each of the four cohorts and overall. ConclusionAndrogen deficiency is a true medical condition in both pre- and post-menopausal women. The most important recommendation is to listen to the patient and consider androgen deficiency when the symptoms are present, even if they seem non-specific. Treatment with androgens has to be monitored carefully because of the possible harmful effects of excessive levels of testosterone.

Hormonal conditions can be tricky to find and complicated to treat. The experts in endocrinology at Cleveland Clinic are here to provide the best care. Testosterone triggers the development of the male internal and external reproductive organs during fetal development. In this article we’ll cover the symptoms of high testosterone, what causes it, how you can test for it and what you can do about it.

Potential risks and side effectsThere is very little clinical research on treating pre-menopausal women. From the small amount of research available, it seems that the androgen levels achieved by treatment, as well as side effects, are the same as those in post-menopausal women. However, some sensitive women may have these effects with a level in the normal range. If testosterone rises above physiological levels, an abnormal lipid profile may occur. There are no side effects to DHEA itself because there are no receptors in the body for DHEA; all side effects are from the conversion product of DHEA, which is testosterone. Women with a history of breast cancer, severe liver disease, or severe deep vein phlebitis should not take androgens, as a certain amount of testosterone will be converted to estrogen.

Thanks to advancements in blood testing technology, assessing testosterone levels has become more accurate and accessible. This article will provide an overview of serum testosterone testing, its role in diagnosing conditions such as low testosterone (also referred to as hypogonadism), and its importance in managing men’s health. Testosterone deficiency has a prevalence of 10%-40% among adult males, and 20% among AYA men aged years, he added. Therefore, Lokeshwar and colleagues hypothesized that serum total testosterone levels will decline in AYA men. This document was written by the Evaluation and Management of Testosterone Deficiency Guideline Panel of the American Urological Association Education and Research, Inc., which was created in 2016.

The Panel recommends that clinicians use the same laboratory with the same method/instrumentation for serial total testosterone measurement. Where possible, clinicians should use LCMS to measure total testosterone levels to maximize accuracy and limit CV between tests in men undergoing testing, particularly in men with very low total testosterone levels. The Panel recognizes that not all laboratories use LCMS technology, and immunoassays may be the only measurement tool available to clinicians. Some authorities have advocated that free testosterone should be the primary measure used to define testosterone deficiency.

Depending on your insurance plan, you may be responsible for some out-of-pocket costs like copays or a deductible. If you have questions about the cost of testing, you can speak with your doctor and insurance plan for more information. Several at-home collection test kits for checking testosterone levels are available without a prescription. These test kits may be sold at your local pharmacy and are available online. If you are noticing several of the symptoms of testosterone deficiency, it’s worth getting your testosterone blood results tested.

As a woman enters menopause, her estrogen level drops, affecting her estrogen-testosterone balance. If you think you are experiencing symptoms of low testosterone or high testosterone, it is always a good idea to check in with a healthcare provider. You can do so easily and conveniently in a virtual women’s health visit or a virtual men’s health visit from Everlywell. For both an adolescent and adult male, 400 ng/dl testosterone is within a healthy range. However, this amount of testosterone is high for a male child or females.

Low testosterone levels can lead to various health problems that significantly impact quality of life, including erectile dysfunction, depression, and increased body fat. Regular monitoring of testosterone levels, especially as men age, helps identify these potential issues early and allows for appropriate lifestyle changes or medical interventions. Men who have low testosterone levels can greatly benefit from testosterone replacement therapy. This therapy increases the body’s testosterone levels so men can benefit from increased sex drive and sperm count, improved erectile dysfunction, and a reduction in other unpleasant symptoms such as fatigue, insomnia, and depression.

Bootstrapping was used to quantify uncertainty in the estimates of these associations. Additionally, Bland–Altman analyses were used to assess the degree to which differences between local and central measurements tracked with the level of testosterone concentrations. Each of the normalizing transformations was then applied to local testosterone measurements obtained from the corresponding cohort. Harmonization procedure reduced intercohort variation between testosterone measurements in men of similar ages. In healthy nonobese men, 19 to 39 years, harmonized 2.5th, 5th, 50th, 95th, and 97.5th percentile values were 264, 303, 531, 852, and 916 ng/dL, respectively. Age-specific harmonized testosterone concentrations in nonobese men were similar across cohorts and greater than in all men.
