Understanding the Free Testosterone Range

Free testosterone Lab Results explained

From there, they might provide guidance on healthy lifestyle changes, such as the tips above. Or, they might suggest a treatment tailored to your specific needs, which could include health testing, hormone therapy, or dietary adjustments. The study found that typical testosterone levels during this stage of life range from approximately 300 to 900 ng/dL.

As it turns out, the symptoms of Low-T aren’t only caused by the total amount of testosterone in your blood. When it comes to low testosterone, the level of your free testosterone may be just as important as your total bio-available testosterone. This is because it is the free testosterone that is readily available in the bloodstream. Imbalanced blood testosterone concentration can lead to various uncomfortable symptoms in both men and women. Your doctor uses it to diagnose conditions caused by too much or too little testosterone.

Research conducted by Snyder et al. (2016), published in the New England Journal of Medicine, provides insights into expected testosterone levels in individuals aged 50 and beyond. Treatment for low free testosterone levels may include hormone replacement therapy (HRT). This involves the use of synthetic testosterone to supplement the body’s natural levels.

In women, though present in smaller quantities, it what is marked by the decrease of the male hormone testosterone? essential for bone strength, ovarian function, and libido. However, testosterone’s influence transcends physical attributes; it also impacts mood, energy levels, and cognitive function. As men age, testosterone levels start to decline at a rate of about 1% per year after the age of 30. This decline can result in various symptoms, including decreased muscle mass and strength, increased body fat, reduced libido, mood changes, and decreased bone density. However, it’s important to note that not all men will experience these symptoms, and some may have testosterone levels within the normal range despite their age. On the other hand, high testosterone levels can also present with noticeable symptoms.

As early adulthood sets in, testosterone levels may continue to fluctuate within this range, but some individuals may experience a slight decline as they progress through their twenties. These variations highlight the dynamic nature of testosterone levels during this crucial phase of life. Testosterone, often hailed as the quintessential male hormone, holds a vital role within the human body.

This age-related variation underscores the importance of using age-appropriate reference ranges when evaluating results. When investigating causes of hyperandrogenism in women, such as PCOS, total testosterone, SHBG, and free androgen index are most useful. Other hormones like luteinising hormone (LH), follicle-stimulating hormone (FSH) and prolactin are sometimes also measured to rule out other causes of irregular periods. SHBG naturally increases with age, but you may be able to reduce this effect somewhat by making sure your diet contains plenty of protein [9]. If your levels are abnormally high, it’s worth exploring whether medications or an underlying health condition may be playing a part in this.

A balanced diet and regular exercise can help maintain healthy testosterone levels and mitigate the risk of imbalance. If your test for total testosterone comes back normal, it could be that a disproportionate amount of your testosterone is « locked up » as bound testosterone. Testing your testosterone levels with your healthcare provider’s guidance can also help you understand how your lifestyle choices may affect this important hormone. Labcorp OnDemand’s Comprehensive Testosterone Test measures total testosterone, free testosterone, albumin and SHBG, providing a complete picture.

Regular exercise, particularly strength training and high-intensity interval training (HIIT) can help boost testosterone production. A balanced diet rich in nutrients, including healthy fats, zinc, vitamin D, and supplements can also play a role in maintaining optimal hormone levels. 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.

So it’s often calculated instead, using total testosterone, SHBG, and albumin levels. The effects of testosterone are more clearly seen in men, but the hormone has important roles in women too. Abnormal levels, low or high, can give rise to symptoms and may be due to an underlying condition. TRT is a treatment suitable for people who have abnormally low testosterone. In this treatment, testosterone injections, pellets, gels, patches, etc., are given to the patients to increase their testosterone levels. So far, this treatment has helped many people with their low testosterone. If you have low testosterone levels, then your doctor will first find the true reason behind this problem.

A study published by Wu et al. (2020) in the Journal of Clinical Endocrinology & Metabolism provides insights into average testosterone levels during the 30s and 40s. When considering normal free testosterone levels during infancy and childhood, it’s essential to understand the baseline levels and the subsequent changes that occur during the growth and development process. A study published in the Journal of Clinical Endocrinology & Metabolism by Johnson et al. (2018) examined testosterone levels in newborns and infants. The study found that typical testosterone levels in newborns are relatively low, ranging from 0.1 to 0.8 ng/dL. Furthermore, high free testosterone levels in men can also have negative effects on the prostate gland.
