A T test involves testing your body’s free and total testosterone involves a blood test, wherein its testosterone concentration is determined using equilibrium dialysis. The test is usually done in the morning when T levels are highest in both men and women. Testogen is a natural dietary supplement that may help you boost bioavailable testosterone.

“We do sometimes initiate treatment on men with a low calculated free T if the total T is borderline,” Dr. Welliver says. If you are a man and this test reveals your free testosterone is lower than normal, your healthcare provider may prescribe testosterone therapy. To further investigate this link, researchers analyzed data from 897 mother–child pairs, including 458 boys. They measured maternal testosterone at 28 weeks of pregnancy using mass spectrometry and later assessed body composition in the children at age seven using Dual X-ray Absorptiometry (DXA). This advanced imaging technique provided detailed measurements of fat mass and lean body mass.

Treating low testosterone levels in men requires a personalized approach, often beginning with Testosterone Replacement Therapy (TRT) to alleviate symptoms like fatigue, mood disturbances, and low libido. TRT, available in forms like injections, gels, and patches, must be monitored for side effects, including cardiovascular and prostate health concerns. Complementing this, lifestyle changes are pivotal; regular exercise, particularly resistance and high-intensity workouts, a balanced diet, weight management, adequate sleep, and stress reduction can naturally enhance testosterone levels. Addressing underlying health issues such as obesity and diabetes is also crucial, as these can contribute to low testosterone.

Therefore, understanding the dynamics of testosterone in females, particularly in response to physical activity, is essential for designing effective, sex-specific exercise interventions. It’s important to note that while these strategies can be effective, they may also carry risks. For instance, testosterone replacement therapy can potentially increase the risk of blood clots, sleep apnea, and prostate issues in men.

Depending on your health goals and concerns, your healthcare provider may recommend testing total testosterone, free testosterone or both. Testosterone testing (you can measure just total T or both total and free T) helps deliver results and sometimes is even used to diagnose health conditions such as erectile dysfunction or infertility. Because free testosterone helps you maintain muscle mass, when your numbers are higher you won’t gain as much fat, (2) he adds.

After the initial assessment, the participants were randomly divided into 2 groups using a random table generator. The control group was advised to walk for 30 min three times a week on alternate days for 16 weeks along with a standard dietary plan. In this protocol, different types of exercises, resistance, endurance, and balance, were integrated with proper warm-ups, cool-downs, and rest intervals, which required minimal setup (with only handheld dumbbells), as shown in Table 1.

A free testosterone test for men is a critical diagnostic tool in evaluating and managing a variety of health conditions, primarily those related to hormonal balance and reproductive health. Testosterone, a vital male hormone, plays a significant role in several physiological processes including muscle mass and strength, bone density, fat distribution, and sexual function. Treating testosterone imbalances requires a comprehensive approach, combining medical interventions with lifestyle modifications. The choice of treatment depends on the underlying cause of the imbalance, the severity of symptoms, and individual patient factors. A collaborative effort between the patient and healthcare provider is essential in achieving the best spot to inject testosterone outcomes, ensuring that treatment not only addresses hormonal imbalances but also enhances overall quality of life.

As T levels decline, so do sperm counts and semen quality, which can lead to issues in fertility, he says. For those who want to grow their family, this can lead to high levels of emotional stress on the individual and family levels. “On a societal scale, this could exacerbate population challenges, particularly in countries already experiencing aging populations and workforce shortages,” he says. The most prominent is a 2007 study published in the Journal of Clinical Endocrinology & Metabolism, which found that men in the 2000s had “substantially” lower testosterone levels compared to men of the same age in the 1980s and 1990s. The decline was observed across all age groups, but researchers said it raised particular concerns regarding younger populations. The normal range for free testosterone can vary based on factors such as age, health status, and laboratory testing methods.

As we proceed to explore the symptoms and effects of testosterone imbalance, the interconnected nature of this hormone with various aspects of health becomes even more evident. Understanding the balance of these two forms of testosterone is vital in diagnosing and treating various health conditions. Typically, total testosterone is measured through blood tests as a first step in evaluating testosterone status. However, if total testosterone levels are borderline or do not correlate with symptoms, measuring free testosterone or bioavailable testosterone (free plus loosely bound to albumin) can provide additional insights. Low testosterone levels (hypogonadism) can have significant health implications. In men, it can lead to infertility, decreased bone density, and diminished muscle mass. Women with low testosterone might experience reduced libido, fatigue, and muscle weakness.

Testosterone therapy did appear to have some positive effects on short-distance mobility, which may require further study to confirm. More than 200,000 American women every year experience hip fractures, and up to three-quarters of them never fully regain their ability to resume normal activities like walking, even after undergoing weeks of exercise rehabilitation. “The standard of care for prostate cancer is androgen deprivation—or ‘chemical castration’—in which you reduce testosterone levels almost to zero,” says Dr. Reina-Campos. “But the role of testosterone and its sensor, which is an androgen receptor on immune cells, is not really well known.” Despite lower concentrations than in men, testosterone plays a crucial role in women’s musculoskeletal health, cognitive function, and cardiovascular well-being54. Women naturally secrete higher total amounts of androgens compared to estrogens, with testosterone being a key androgen and dihydrotestosterone (DHT) forming through peripheral metabolism51.
