Landmark Study Defines Normal Ranges for Testosterone Levels

People with past prostate or breast cancer or those with untreated sleep apnea should avoid TRT. It may also exacerbate conditions such as polycythemia, where there is an excess of red blood cells. For adult men, a normal testosterone level is often considered to be between 300 and 1,000 ng/dL.

The level of testosterone increases in the blood for a number of days after the injection, and many women reach levels high enough to cause side effects. A current study of testosterone patches suggests that this may be an effective treatment option within a few years. There are limited data on absorption kinetics and consistency of absorption of testosterone. Because levels of testosterone have to be monitored carefully and none of these products are standardized, they are not widely recommended for use. Although not officially approved for use by women in the United States, various pharmacies can compound testosterone in a cream or 1% gel form, as these have been approved for men. The search yielded 15,217 references, 546 (enrolling approximately 350,000 men) of which were used to support guideline statements. Minimal data were found regarding outcomes of frailty, risk of venous thromboembolism, hyperestrogenemia, sleep apnea, prostate biopsy, recurrence of treated prostate cancer, and incidence of breast cancer.

To determine what’s a good T level for your age, you also need to look at the clinical picture. The Food and Drug Administration (FDA) advises against getting TRT for low levels caused by aging alone. The best way to check for low testosterone is to visit a doctor for a physical exam and a blood test. Testosterone levels reach their peak around age 18 before declining throughout the remainder of adulthood. Excess testosterone in male children can lead to precocious (early) puberty, which is when puberty begins before the age of nine.

It plays a particularly important role in men, where it promotes muscle mass development, affects sex drive, and regulates sperm production. This hormone also influences behaviors like competitiveness and aggression. Excessive steroid use can raise testosterone levels in the blood and decrease the function of the testes, causing a person’s body to stop producing testosterone. High testosterone levels are unusual in adult males, while children with high testosterone levels may have a growth spurt or start puberty early. High testosterone in all sexes can cause infertility, obesity, and in some cases, metabolic disorders. In men, testosterone levels normally start to decline after the age of 30. Average testosterone levels for men between the ages of 40 and 49 are 252 to 916 ng/dL.

Identifying symptoms of low testosterone in men over 40 through a serum testosterone test can help differentiate between normal aging and a medical condition that requires intervention. The treatment for low-T is known as Testosterone Replacement Therapy (TRT). TRT involves delivering extra testosterone to your body so that your levels of the hormone can recover, causing your symptoms to ease.

Low levels of testosterone in males and females can lead to a range of serious health problems. Having your testosterone levels checked regularly can empower you to seek treatment for hormone replacement therapy if needed and make healthy lifestyle changes that naturally increase or balance your testosterone levels. But that doesn’t mean you should simply sit back and wait for science to tell you what to do. Keep your mind young and supple with mental activity, physical exercise, good nutrition, and regular medical care. And you can also get many of the purported benefits of testosterone for your body without any of its risks.

These findings require further follow-up as they demonstrate that transference may hypothetically occur in the absence of skin-to-skin contact. While there are three injectable drugs, two of them are short-acting and one is long-acting. Finally, testosterone pellets are also available in branded form, with no generic agents currently available.

Guidelines cannot include evaluation of all data on emerging technologies or management, including those that are FDA-approved, which may immediately come to represent accepted clinical practices. For this reason, the AUA does not regard technologies or management which are too new to be addressed by this guideline as necessarily experimental or investigational. Given the increasing incidence of both testosterone deficiency and prostate cancer with advancing age, it is common for the two conditions to co-exist in older men.

Still, many don’t understand the science or difference between free and total testosterone. Every guy can benefit from learning more about testosterone and how it affects the body. If you’re having symptoms of low testosterone—like low libido, fatigue, depression, erectile dysfunction, or difficulty concentrating—talk to your doctor about getting your testosterone levels checked. If your levels come back low and you have symptoms of low testosterone, you may be a candidate for testosterone therapy. An estimated 1 in 50 men have low-T and experience symptoms such as lessened energy, decreased libido (sex drive), erectile dysfunction, lack of concentration, or trouble sleeping.
