We source research from peer-reviewed medical journals, top selling testosterone boosters government agencies, leading academic institutions, and respected advocacy groups. We also go beyond the research, interviewing top experts in their fields to bring you the most informed insights. Every article is rigorously reviewed by medical experts to ensure accuracy.

It is important to be aware of these symptoms in order to seek appropriate medical attention and treatment if necessary. On the other hand, levels of free testosterone that are above the normal range may indicate an excess of the hormone. This condition, known as hyperandrogenism, can lead to symptoms such as increased aggression, acne, excessive body hair growth, and an enlarged prostate. Hyperandrogenism can be caused by various factors, such as tumors in the testes or adrenal glands, certain medications, or genetic disorders.

Because testosterone levels vary from day to day and hour to hour, if a low or high level is found, the test is usually repeated. It’s hard to give an exact definition of “normal” testosterone levels without knowing someone’s lifestyle (if you’re inactive, you likely don’t need as much T as if you run marathons, for example). For an organ like the heart, free testosterone helps muscles pump more efficiently. Some research (1) suggests that men with congestive heart failure who also have low free testosterone have poorer health prognoses. If your free testosterone levels are below normal, you might have a lower risk of clogged arteries or a heart attack, he adds. High free estradiol can interfere with male reproductive health, energy levels, and emotional well-being. It can also increase the risk of prostate issues and cardiovascular complications when severely imbalanced or prolonged.

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. Both men and women with low % Free Testosterone may experience difficulties with bone density, leading to a higher risk of osteoporosis. Additionally, low % Free Testosterone is sometimes linked to metabolic issues, such as insulin resistance or metabolic syndrome, which can increase the risk of cardiovascular diseases. Therefore, detecting and addressing low % Free Testosterone levels is essential for maintaining overall health and well-being.The prevalence of low % Free Testosterone varies with age and gender. In men, it’s estimated that about 20% of those over 60, 30% over 70, and 50% over 80 years old have low testosterone levels. In women, the prevalence is less well-documented, but it’s known to increase after menopause.

These hormonal shifts are a natural part of the maturation process, playing a crucial role in the transition from childhood to adolescence. 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. It is crucial to interpret free testosterone levels in the context of a woman’s overall health and symptoms. For example, a woman with low energy, low libido, and reduced muscle mass may benefit from having a free testosterone level closer to the upper end of the reference range.

It is responsible for maintaining muscle mass, bone density, energy levels, and sex drive in men. Understanding the normal range of free testosterone levels in men is crucial for assessing and diagnosing hormone imbalances or deficiencies. Because free testosterone plays a critical role in these physiological processes, measuring its percentage can provide a more accurate picture of an individual’s hormonal balance than total testosterone levels alone.

This includes follow-up blood tests to assess hormone levels and evaluate the effectiveness of the treatment, as well as monitoring for potential side effects. Patient education about the signs of hormone imbalance and the importance of adhering to treatment regimens is also key. Similarly, conditions that alter SHBG levels can affect the amount of free testosterone without necessarily changing the total testosterone. For instance, aging, certain medications, and health conditions like liver disease can increase SHBG levels, while obesity and insulin resistance might decrease them. In most cases, men need to have both low levels of testosterone in their blood and several symptoms of low testosterone to go on therapy. But if you do not have any key symptoms, especially fatigue and sexual dysfunction, which are the most common, it is not recommended you go on the therapy given the uncertainty about long-term safety.

It is calculated by adding free testosterone to albumin-bound testosterone. There are two important testosterone tests that are used to measure free testosterone concentration. It measures the amount of total testosterone as well as the amount of free testosterone.
