Testosterone is a vital hormone that significantly influences various bodily functions in both men and women. It regulates sex drive, fat distribution, muscle size and strength, bone density, and red blood cell production. Testosterone also contributes to physical development during puberty and maintains essential bodily functions throughout life. As we age, it's natural for testosterone levels to decrease in both men and women, which can impact overall health and vitality.
Low levels of testosterone can result in decreased energy, reduced strength, and mood disturbances, whereas excessively high levels might cause increased aggressiveness and sleep problems. In this article, we will discuss what constitutes normal testosterone levels and provide insights on managing both high and low levels. Understanding these aspects is key to addressing imbalances that could affect your health and quality of life.

What Is Testosterone?
Testosterone is classified as an androgen, a type of hormone that plays a key role in the development and maintenance of male sexual characteristics, although it is important for both genders. In males, the primary site of testosterone production is the Leydig cells in the testes. Females also produce testosterone but in significantly lower amounts, mainly in the ovaries and the adrenal glands, particularly in the zona reticularis. This hormone's production influences various bodily functions and contributes to the physiological differences between genders.
In addition to its role in sexual and reproductive development, testosterone is involved in a number of body functions including the regulation of libido, bone mass, fat distribution, muscle size, and the production of red blood cells and sperm. For both males and females, adequate levels of testosterone are essential for overall health. The balance of testosterone production is regulated by the hypothalamic-pituitary-gonadal axis, which adjusts hormone levels in response to the body's needs (18).
Testosterone Functions
In males, testosterone is instrumental during puberty, triggering the development of the testes and prostate and promoting secondary sexual characteristics such as increased muscle and bone mass and the growth of body hair. The hormone is not only essential for the development of male external genitalia in the fetus but also for the features that emerge during adolescence. Its role extends into adulthood, maintaining muscle strength and mass, red blood cell production, and influencing male fertility and libido (18).
Though present at much lower levels in females, testosterone also supports various bodily functions. It contributes to bone strength and the development of lean muscle mass, playing a role in female libido and mood regulation. Moreover, testosterone is thought to have a protective effect against osteoporosis and bone deterioration in women. Despite its lower concentrations, the precise regulation of testosterone levels is imperative for balancing bodily functions and ensuring overall health in females, just as in males (18).
Normal Testosterone Levels By Age and Sex
Testosterone levels peak during puberty and decrease over time for both men and women.
Aging: Natural processes lead to a gradual decrease in testosterone over time.
Body composition: Higher body mass index (BMI) and body fat percentages are linked to lower testosterone.
Physical activity: Resistance and high-intensity training generally boost testosterone production.
Substance use: Smoking and excessive alcohol consumption can reduce testosterone levels.
Sleep patterns: Quality and duration of sleep can significantly influence hormone levels.
Symptoms of Imbalanced Testosterone Levels
Symptoms related to testosterone imbalances differ based on the corresponding levels:
Low Testosterone Symptoms
Reduced interest in sexual activity
Unusual tiredness
Loss of muscle mass and strength
Difficulty in achieving or maintaining an erection
Mood changes like depression
High Testosterone Symptoms
Mood swings and increased aggression
Acne and oily skin
Sleep disturbances
Increased muscle mass
Diagnosing Testosterone Imbalances
The process of diagnosing testosterone imbalances involves a careful evaluation of symptoms, medical history, and blood tests. To accurately measure testosterone levels, blood tests for both total and free testosterone are necessary. The best time for testing is typically in the morning, between 8 AM and 10 AM, when testosterone levels are at their peak. If initial tests show abnormal levels, further testing may include repeating the testosterone test along with assessments of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) to differentiate between primary and secondary causes of testosterone imbalance (18).
Managing and Treating Testosterone Imbalances
Managing and treating testosterone imbalances is benefitted by an integrative approach, personalized using medical interventions and supportive lifestyle changes.
Treatment Options for Low Testosterone
For low testosterone, the primary treatment is Testosterone Replacement Therapy (TRT), which is administered through various methods such as injections, patches, gels, or subcutaneous pellets. This therapy aims to restore testosterone levels to their normal range, helping to alleviate symptoms like fatigue, low libido, and muscle loss.
Alongside TRT, significant emphasis is placed on lifestyle modifications to enhance testosterone production naturally. These changes include improving diet, increasing physical activity focusing on resistance and endurance exercises, managing stress, ensuring sufficient sleep, and maintaining a healthy weight.
Treatment Options for High Testosterone
In cases of high testosterone, treatment often involves medications designed to inhibit testosterone production, particularly if the condition is caused by underlying health issues such as tumors or adrenal disorders. Options may include:
Androgen receptor blockers or other hormonal pathway modulators
Adjustments in diet and exercise to help regulate hormone levels
Regular cardiovascular and strength training to support the overall balance of hormone levels
Addressing complications associated with high testosterone
The Impact of Testosterone on Overall Health
Prolonged imbalances in testosterone levels can significantly impact cardiovascular health.
Low testosterone is associated with an increased risk of cardiovascular diseases, such as atherosclerosis and heart attacks, due to its role in vascular function and blood flow regulation.
High levels of testosterone, conversely, can contribute to aggressive behaviors and risky decisions, indirectly elevating the risk of hypertension and cardiovascular incidents.
Additionally, both high and low testosterone levels can affect lipid profiles, influencing the development of cardiovascular conditions by altering cholesterol and other critical blood lipids.
In terms of bone health, testosterone imbalances are closely linked to the risk and progression of osteoporosis.
Adequate levels of testosterone are crucial for maintaining bone density; low levels can lead to weakened bones and an increased risk of fractures, particularly in older adults where natural hormone levels decline.
Conversely, excessively high testosterone levels, often due to steroid use, can disrupt the balance of bone remodeling, leading to potential bone degradation over time. Therefore, managing testosterone levels is vital for preventing osteoporosis and maintaining overall bone integrity.

Key Takeaways
Understanding your testosterone levels is essential for good health, as this hormone plays a key role in many bodily functions and varies by gender and with age.
Maintaining balanced testosterone is critical because imbalanced levels can lead to several health issues.
Low testosterone might cause fatigue, muscle weakness, and mood changes, while high levels can increase aggression and cause sleep disturbances.
If you experience symptoms like these, lifestyle adjustments and medical treatments such as Testosterone Replacement Therapy can help stabilize your hormone levels.
If you suspect a testosterone imbalance, talk to your healthcare provider for a proper evaluation.
