Testosterone levels by age chart: Female

Normal Testosterone Levels by Age

If a woman is experiencing symptoms of too much testosterone, it’s best to seek treatment to find the underlying cause. Medical, natural, or a combination of both types of treatment may help regulate testosterone levels. Many women with high testosterone levels will have irregular menses or no period at all. However, research reveals that some pre-menopausal women with high testosterone levels may be asymptomatic, meaning they never experience symptoms. It’s important to note that for people assigned female at birth (AFAB), there’s no exact number for determining high testosterone levels, also known as hyperandrogenism. Testosterone levels begin to decline when you reach your mid-thirties, and drop further as you age. Changes in mood, energy levels, or cognition might signal low testosterone levels.

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.

If you have questions about testosterone testing, talk with your health care provider, who can discuss whether this testing is appropriate in your situation. The result is that many men are being denied treatment despite having low levels of testosterone. For example, many men with low testosterone are treated with anti-depression medication (SSRIs) instead of treating the real cause of their mental health issues. These medications may even reduce testosterone production further, exacerbating the condition. Other men have been told they are “too muscley” to have low testosterone, stemming from a misunderstanding of what testosterone does.

According to research, total testosterone falls by around 1.6% on average per year, while free testosterone drops by 2 to 3% per year (Mohr et al. 2005; Zirkin and Tenover 2012). Testosterone is essential for building and maintaining muscle mass and strength. Men with low testosterone may experience a decrease in muscle mass, strength, and endurance. Low testosterone can lead to a decrease in sexual desire and function. Testosterone that is attached, or bound, to proteins is not available to androgen receptors. Androgen receptors are a kind of hormone that plays a hugely important role in many aspects of bodily function. The reproductive, cardiovascular, neural, immune, and musculoskeletal systems all rely on androgen receptors and, thus, on free testosterone.

These pellets steadily release testosterone over three to six months, minimizing the need for frequent applications or injections. There are no significant restrictions following the test, and you can resume your normal activities immediately. If you experience minor bruising or soreness at the puncture site, applying a cold compress can help alleviate discomfort. Our goal is to help men achieve optimal hormonal balance, considering their unique age-related testosterone changes.

However, Ramasamy said that since there’s a possibility of overlap between participants in both studies, the percentages can’t be added. By Julie MarksMarks is a Florida-based health writer with a bachelor’s degree in broadcast journalism and creative writing. This immunoassay is intended for the in vitro quantitative determination of testosterone in human serum and plasma. This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.

Typically, HRT supplements estrogen and progesterone (female hormones), but certain therapies can also deliver testosterone. “Since testosterone plays a key role in a woman’s sexual response by increasing blood flow to the genitals as well as nerve sensitivity, this decline negatively impacts libido, responsiveness, and orgasm,” Dr. Dorr says. Too much testosterone can also cause hypertension, or high blood pressure (8). The average male who reaches 70 years old will have testosterone production that’s 30 percent below his peak (5). But you don’t have to experience the negative symptoms that come with hormone declines. Healthcare professionals recognize the wide variability of laboratory ranges. The Centers for Disease Control and Prevention (CDC) also has a CDC Hormone Standardization Program to increase the accuracy of laboratory tests.

For adult men, normal testosterone levels generally range from 300 to 1,000 ng/dL, though these values may vary slightly depending on the laboratory and the individual’s age. A serum testosterone level measures the amount of testosterone circulating in your bloodstream. Testosterone, which is primarily produced in the testes and, to a lesser extent, in the adrenal glands, is classified as an androgen, or male sex hormone. It is responsible for defining key male characteristics, such as a deeper voice, facial hair, and muscle development. Beyond these traits, testosterone also supports critical aspects of overall health, including bone strength, red blood cell production, and mental well-being. As with any medical reference range, it’s important to remember that individual variations exist, and what’s considered “normal” for one person might not be the same for another. We sought to minimize the influence of these systematic differences by harmonizing all measurements to a higher order standard prior to the estimation of reference ranges.
