Testosterone Therapy: What Men Need to Know About Low T and TRT Treatment Los Angeles Times

What Are Normal Free Testosterone Levels By Age?

This decline, often referred to as andropause or male menopause, can lead to a decrease in muscle mass, bone density, libido, and changes in mood and cognitive function. While this decline is a normal part of aging, for some individuals, it can lead to significantly lower than normal levels, necessitating medical intervention. It regulates libido (sex drive) in both men and women, plays a key role in sperm production, and influences mood and energy levels. Additionally, testosterone is crucial for maintaining muscle mass and strength, bone density, and even the distribution of fat in the body. Produced mainly in the testes, testosterone is an androgen (i.e., sex hormone) that plays a role in characteristics like muscle mass, bone density, fat distribution, facial and body hair growth, sperm production, sex drive and more. Furthermore, certain medical conditions or medications may disrupt testosterone levels. Conditions like hypogonadism or obesity-related hormonal imbalances can lead to low testosterone, while medications like corticosteroids or opioids may also affect hormone production.

The amount of testosterone in your blood is measured in nanograms per deciliter (ng/dL). It can help doctors identify the causes of various conditions such as erectile dysfunction, hair loss, and osteoporosis [3]. Unlike bound testosterone, free T is readily available to act on cells in target tissues. Albumin-bound testosterone has a weak bond and is, therefore, also classified as bioavailable testosterone. Hone’s hormone assessment paints a full picture of what’s going on with your free testosterone and total testosterone. The test also measures several biomarkers, including SHBG, estradiol, luteinizing hormone (LH), and prostate-specific antigen (PSA), and of course, both free and total T. If you are suffering from the symptoms of low testosterone, most of the time your doctor will only test for your total testosterone.

It’s essential to recognize that each individual’s testosterone journey is unique, and seeking professional advice is highly encouraged. Whether you are experiencing symptoms of low or high testosterone, a healthcare professional can provide personalized guidance, conduct necessary tests, and recommend appropriate interventions. Therefore, monitoring % Free Testosterone levels can provide valuable insights for healthcare providers, guiding both diagnosis and treatment strategies for hormone-related disorders across different age groups and genders.

Its influence stretches beyond mere physical characteristics, impacting emotional well-being, cognitive functions, and overall life quality. The growing interest around male birth control pills came with good news for men suffering from extremely high testosterone levels. The effects of a pill containing dimethandrolone undecanoate (DMAU) were investigated and found to reduce both testosterone concentration and suppress serum LH production in the study’s subjects [19].

These readings were taken at the beginning of the intervention on the 4th, 14th, and 24th days of the menstrual cycle for all participants. The second set of readings occurred during the program’s 6th to 8th week (mid-intervention), again on the 4th, 14th, and 24th days of the menstrual cycle. The final set of readings occurred during the study’s 14th to 16th week (post-intervention). In conclusion, understanding and managing testosterone levels throughout different stages of life are crucial for maintaining overall health and well-being. We have explored key points regarding normal free testosterone levels at various ages, factors affecting testosterone levels, the importance of testing, and the signs and symptoms of imbalances. Testosterone, often hailed as the quintessential male hormone, holds a vital role within the human body. It is a powerful androgen that contributes to various aspects of physical, mental, and sexual well-being.

Total T is the total amount of testosterone, measured in nanograms per deciliter (ng/dL) of blood, in your body. On the other hand, free testosterone is the type of testosterone your body uses; it’s vital to your health. That’s also why it’s best to get your T levels tested through your doctor instead of just going out and getting prescribed testosterone one on your own. A physician can help you dive into your individual circumstances and help you get the right treatment for your body.

The higher levels of testosterone in women can have serious effects on the fetus. If your doctor suggests you the Free Testosterone test, it is very significant for pregnant women to undergo the Free Testosterone test.

Some research suggests a potential link between higher exposure to endocrine-disrupting chemicals (EDCs) and lower testosterone levels, says Houman. This is likely because they can disrupt both endocrine function and healthy metabolism. A 2023 study in Environmental Research reports a link between EDCs and a decrease in serum testosterone. And other research has shown that these chemicals, as their name suggests, can negatively impact the endocrine (hormone) center, leading to disruptions in hormone balance. Meanwhile, a 2017 study in Current Obesity Reports found that endocrine-disrupting chemicals can promote the accumulation of adipose (fat) tissue and cause weight gain.

But be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don’t need a prescription and any illegal drugs you may use. The pituitary gland in your brain controls the amount of testosterone your body makes. With spatial transcriptomics, Dr. Reina-Campos can track how T cells move, like glowing constellations, through our tissues.
