Understanding free testosterone vs total testosterone: A comprehensive guide

Free testosterone Lab Results explained

The most significant changes in testosterone occur during puberty when levels surge to support the development of secondary sexual characteristics, such as facial hair growth, deepening voice, and muscle development. These hormonal shifts are a natural part of the maturation process, playing a crucial role in the transition from childhood to adolescence. As we navigate through life, several factors come into play that can influence testosterone levels, shaping our overall hormonal balance. Firstly, age-related changes in testosterone production have a significant impact. It’s natural for testosterone levels to gradually decline with age, as the body’s hormone production slows down.

In both men and women, persistently high levels of % Free Testosterone can lead to symptoms like acne, hair loss, increased body hair, mood swings, and even cardiovascular issues over time. It’s important to note that the prevalence of elevated % Free Testosterone varies; for instance, PCOS affects about 6-12% of women of reproductive age, making it a relatively common cause of high % Free Testosterone in women. There are a variety of methods to test your testosterone levels, both from the comfort of home and in the clinic or lab. Saliva and blood collections are both valid and used for different aspects of clinical practice, as are the free and total testosterone biomarkers. Whichever method you end up choosing, it’s always best to discuss your results with your healthcare provider to set up next steps that are best for you. While you’re with them, a doctor may recommend blood tests to assess hormone levels, says Houman.

What goes on in the womb does not stay in the womb as prenatal hormone exposure plays a critical role in shaping childhood growth and body composition. There is a moment in every man’s life when they are at their peak – a time when vitality, strength, and energy seem boundless. It’s no coincidence that this peak often aligns with the highest levels of testosterone in the body. Testosterone, a vital hormone predominantly found in males, plays a crucial role in numerous aspects of health and well-being. However, as the years pass, testosterone levels naturally decline, leaving many men feeling farther and farther away from their physical peak. This hormone influences many aspects of a man’s physical and emotional well-being, including muscle mass, bone density, mood, and overall vitality. Understanding your free testosterone range is essential for maintaining optimal health, especially as you age.

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.

The team also took other anthropometric measurements, such as body weight, body mass index (BMI), and abdominal circumference. In men, what’s considered “normal” tends to decrease with age, while in women, levels may increase slightly after menopause. This age-related variation underscores the importance of using age-appropriate reference ranges when evaluating results. Lastly, it’s important to recognize that % Free Testosterone typically decreases with age in men, a factor that contributes to various age-related health issues.

Although primarily prescribed as a diuretic to treat hypertension, spironolactone acts as an anti-androgen. The drug also increases the concentration of SHBG in the blood, providing a binding substrate to testosterone and effectively reducing the free T concentration [18].

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].

Testosterone therapy can make you feel younger and stronger, and improve your confidence, so you can continue to do all the things you enjoy most in life. But the only way to be sure if you need a prescription for testosterone replacement is to have your symptoms evaluated and your blood tested. The FDA currently advises against treating men with low testosterone caused only by aging. Scientists need to know how androgen deprivation affects cancer-fighting T cells. With spatial transcriptomics, Dr. Reina-Campos can track T-cell activity before and after androgen deprivation. He can uncover exactly which kinds of T cells jump into action and how those T cells travel through tissues to find their targets. Formal informed consent was obtained from all individual participants included in the study.

So, the integrated exercise regimen was designed that does not require a gym setup or expensive equipment, yet delivers the benefits of a structured workout. Each exercise in the regimen was carefully selected for its ability to engage multiple muscle groups while remaining accessible and cost-effective. The regimen focuses on key aspects of functional fitness, including strength, flexibility, balance, and coordination—essential components for enhancing overall muscular strength in women.
