Low Testosterone Symptoms in Men: Signs, Causes and How to Treat
Key Takeaways
Prevalence: Low testosterone affects approximately 40% of men aged 45 and older, though it can impact younger men as well.
Primary Signs: Common indicators include low libido, erectile dysfunction, unexplained fatigue, and loss of muscle mass.
Mental Health Impact: There is a strong link between low T and mood disorders, including irritability, anxiety, and depression.
Diagnosis: Accurate diagnosis requires blood work, typically performed in the morning when levels are highest.
Treatment Options: Solutions range from lifestyle adjustments (diet, sleep, exercise) to medical interventions like Testosterone Replacement Therapy (TRT).
You might feel like you are slowing down. Maybe your energy isn't what it used to be, or your workouts yield fewer results than they did a few years ago. Many men brush these changes off as simple aging, but they often point to a physiological decline in hormones.
Testosterone is the primary male sex hormone. It regulates sex drive, bone mass, fat distribution, muscle mass, and the production of red blood cells and sperm. When levels drop below a healthy range (a condition medically known as hypogonadism) it affects the entire body.
At Anderson Longevity Clinic, we focus on identifying the root cause of these symptoms rather than just managing them.
What Causes a Man’s Testosterone Level to Drop?
Testosterone levels naturally peak during early adulthood and begin to decline gradually around age 30. This drop is usually about 1% per year. However, certain factors can accelerate this process and lead to levels that are lower than what is considered healthy for your age group.
Aging and Physiology
The most common cause is the natural aging process. As you get older, the testes produce less testosterone. Additionally, your body produces more Sex Hormone-Binding Globulin (SHBG). This is a protein that binds to testosterone circulating in your blood. When testosterone is bound to SHBG, your body cannot use it. This effectively lowers your "free" or available testosterone.
Body Composition and Weight
There is a direct connection between waist circumference and hormone health. Fat cells metabolize testosterone into estrogen, which lowers your T levels. Research indicates that moderate obesity can increase the risk of low testosterone significantly. Studies have shown that men with obesity are far more likely to experience hypogonadism compared to those with a healthy body mass index..
Lifestyle Factors
Your daily habits play a major role in hormonal balance. High levels of stress raise cortisol, a hormone that works against testosterone. Excessive alcohol consumption and the use of certain medications (such as opioids or glucocorticoids) can also suppress your testosterone production.
Top Signs of Low Testosterone in Men
Symptoms of low testosterone are often subtle at first. They can manifest physically, sexually, and cognitively. If you notice a combination of the following signs, it may be time to check your levels.
Sexual Function Changes
Sexual health is often the first area where men notice a problem.
Low Libido: A sudden or gradual drop in interest in sex is one of the most reliable indicators of low T.
Erectile Dysfunction (ED): While testosterone is not the only factor in erections, low levels can make it difficult to achieve or maintain one.
Reduced Semen Volume: Testosterone aids in the production of semen. Low levels can lead to a noticeable decrease in volume during ejaculation.
Physical Changes
Testosterone helps build and maintain the male physique. When it drops, your body composition shifts.
Loss of Muscle Mass: You might notice your arms or chest shrinking despite maintaining your gym routine.
Increased Body Fat: Specifically, men with low T may develop more visceral fat around the abdomen. Sometimes, men may also experience gynecomastia (enlarged breast tissue).
Hair Loss: While genetics play a huge role in balding, low T can lead to a loss of body and facial hair.
Chronic Fatigue: This is distinct from simple tiredness. It is a deep sense of exhaustion that does not improve significantly with rest. You may find it hard to get motivated for exercise or daily tasks.
How Does Low Testosterone Affect Mood and Mental Health?
The impact of hormones extends to the brain. Testosterone acts as a neurosteroid and influences mood and cognitive function. When levels are insufficient, mental health often suffers.
The Link to Depression
There is a documented overlap between the symptoms of depression and hypogonadism. Research suggests that men with low testosterone are more likely to report symptoms of depression, including sadness and a lack of motivation. This can create a confusing cycle where a man is treated for depression with antidepressants, which may not address the underlying hormonal root cause.
Irritability and "The Grumpy Male" Syndrome
Low T can manifest as increased irritability, low tolerance for stress, and unexpected mood swings. This is sometimes referred to as "irritable male syndrome." Men who were previously calm may find themselves snapping at loved ones or feeling easily overwhelmed by minor annoyances.
Cognitive Decline and "Brain Fog"
Many men report a lack of mental clarity. You might experience trouble concentrating, memory lapses, or a general feeling of "fogginess." Testosterone receptors exist throughout the brain, and adequate levels are required for optimal cognitive performance.
What To Do if I Have Low Testosterone Signs?
If you identify with the symptoms above, the next step is clinical verification. You cannot diagnose low testosterone based on symptoms alone, as conditions like thyroid issues or iron deficiency can mimic low T.
1. Schedule a Blood Test
The only way to confirm hypogonadism is through serum testosterone testing. Anderson Longevity Clinic can confirm your hormone levels through bloodwork.
Timing is Key: Testosterone levels fluctuate throughout the day and peak in the early morning. Standard practice requires blood to be drawn in the mornings for the most accurate reading.
Total vs. Free Testosterone: A standard test measures "Total Testosterone." It is also important to measure "Free Testosterone" (the amount not bound to proteins) and SHBG. You might have normal total testosterone but low free testosterone. This would still cause symptoms.
2. Consult a Specialist
General practitioners may only look at the broad reference range, which varies widely (often 300 to 1,000 ng/dL). A clinic specializing in longevity and hormone health, like Anderson Longevity Clinic, looks at "optimal" levels rather than just "normal" levels. We interpret your lab results in the context of your specific symptoms and health goals.
3. Review Your Medical History
Be prepared to discuss your sleep patterns, stress levels, current medications, and diet. This helps the provider determine if your low T is "primary" (a problem with the testicles) or "secondary" (a problem with the pituitary gland or hypothalamus).
What Are the Treatments for Low Testosterone?
Treating low testosterone often involves medical intervention.
Testosterone Replacement Therapy (TRT)
For many men, lifestyle changes alone are not enough to restore levels to an optimal range. In these cases, Testosterone Replacement Therapy (TRT) can be an effective medical treatment.
TRT introduces exogenous testosterone to the body to help restore levels to a healthy range. The goal is to relieve symptoms and provide long-term health benefits, such as improved bone density and cardiovascular protection.
Common methods of administration include:
Injections: This is a common and effective method where testosterone is injected weekly or bi-weekly. It allows for precise dosage adjustments.
Topical Gels/Creams: These are applied daily to the skin. They are non-invasive but require care to avoid transferring the medication to women or children.
Pellets: Small pellets are implanted under the skin (usually in the hip area) and release testosterone consistently over 3 to 6 months.
At Anderson Longevity Clinic, we do not believe in a one-size-fits-all prescription. We monitor your blood work regularly to verify that your levels remain healthy during treatment.
