Understanding Testosterone

Before looking into “what are signs of low testosterone in males?”, it’s first important to understand what testosterone is.

Testosterone is a hormone that plays a central role in the male body. Produced primarily by the testicles, testosterone governs the development of male characteristics during puberty such as:
  • A deeper voice
  • Growth of body and facial hair
  • Muscle strength

Testosterone in Adulthood

Continuing its role into adulthood, testosterone helps maintain key bodily functions. For instance, it:
  • Supports the production of red blood cells
  • Maintains bone density
  • Regulates mood
  • Fuels sex drive in males
  • Plays an indispensable role in sperm production
To put it simply, testosterone keeps the male body ticking, supporting many of the functions that define manhood.

Normal Testosterone Levels

Testosterone levels in males vary, but they are often within a range of 270 to 1070 ng/dL (nanograms per deciliter). Most males have testosterone levels between 300 and 800 ng/dL.

These levels are at their highest during adolescence and early adulthood, then gradually decline at a rate of about 1% per year after age 30.

Causes of Low Testosterone

What are signs of low testosterone in males? The decline of testosterone levels in males can stem from several factors.


Age is a leading factor, as the natural decrease starts around the age of 30. This is a part of the normal aging process and not necessarily a cause for concern.
But, there are instances when testosterone levels can drop significantly, leading to a condition known as hypogonadism. This can occur due to issues with the testicles or the pituitary gland, which controls the production of testosterone.1

Certain Diseases

Certain diseases can also cause testosterone levels to plummet. These can include:
  • Type 2 diabetes
  • Obesity
  • Liver or kidney disease

Other Physical Causes

Other causes include:
  • Hormonal disorders
  • Infection
  • Injury to the testicles
  • Chemotherapy or radiation treatment for cancer

Lifestyle Factors

Lifestyle factors also play a role. Chronic stress, poor nutrition, lack of sleep, and alcohol abuse can all contribute to lower testosterone levels.

What Are Signs of Low Testosterone in Males?: Differentiating from Other Conditions

What are signs of low testosterone in males? Certain medical conditions can mimic the signs of low testosterone in males, making it difficult to immediately identify if testosterone levels are the root cause of symptoms.2

Some conditions with similar signs include:3
  • Depression
  • Diabetes
  • High blood pressure
  • Thyroid problems


For instance, depression can lead to:
  • Changes in mood
  • Reduced energy
  • Decreased interest in activities
These symptoms might get mistaken for signs of low testosterone.

Other Conditions

Diabetes can also cause fatigue, weight changes, and lower libido. Similarly, thyroid issues and high blood pressure can lead to fatigue and changes in mood.

Differentiating Signs and Symptoms

If you’re asking “what are signs of low testosterone in males?”, it’s essential to differentiate them from symptoms of other health conditions. While there’s some overlap, certain symptoms are more specific to low testosterone.

What Are Signs of Low Testosterone In Males That Are Common?

Some common signs of low testosterone include:
  • Reduced sex drive
  • Difficulty with erection
  • Low semen volume
  • Hair loss
  • Fatigue
  • Loss of muscle mass
  • Increased body fat
  • Decreased bone mass
While other conditions can cause similar symptoms, a combination of these signs might indicate low testosterone.

Examples of Low Testosterone

For instance, both depression and low testosterone might lead to fatigue or low mood. But, when these signs are accompanied by a reduced sex drive or issues with erection, the likelihood of low testosterone becomes higher.

Aging-Related Changes vs. Low Testosterone

As men age, there are certain expected changes that occur. Energy levels might decrease, weight could increase, and the intensity of sex drive might lessen. It’s important to note that these changes can be a normal part of aging and are not necessarily indicative of low testosterone.

But, if these changes are drastic, combined with other symptoms like a significant loss of muscle mass, body hair, or bone density, or if they cause distress or affect quality of life, it could be signs of low testosterone in males.

Diagnostic Process

Identifying “what are signs of low testosterone in males?” often starts with a thorough look into your medical history. During this step, your doctor will ask about your symptoms, including when they began, their severity, and their impact on your daily life.
They might ask about any previous or existing health issues, including those that could affect testosterone levels such as liver disease, kidney disease, or hormonal disorders.
Additionally, lifestyle factors are also important. Questions about stress, exercise, diet, and alcohol consumption can help your doctor gather a comprehensive understanding of factors that might contribute to your symptoms.

Physical Examination

The next step involves a physical examination. Your doctor will check for physical signs of low testosterone. This might include examining:
  • The body 
  • Facial hair
  • Breast size
  • Size and consistency of the testes
  • The presence of any fat distribution typical of low testosterone
While these physical signs might not definitively prove low testosterone, they do provide additional information that can guide further testing.

Blood Tests

What are signs of low testosterone in males? One of the most reliable ways to identify low testosterone levels is through blood tests. A blood sample gets taken, often in the morning when testosterone levels are at their highest, and it is then tested for total testosterone.
Sometimes, more than one blood sample is needed to get accurate measurements due to the natural fluctuations of testosterone levels throughout the day.
If the testosterone level is lower than normal, the doctor might order additional blood tests to rule out any potential underlying conditions that could be causing low testosterone. These include thyroid disorders or pituitary gland problems.

Physical Manifestations Indicating Low Testosterone

One of the many roles testosterone plays in the body is helping to build and maintain muscle mass. What are signs of low testosterone in males? If you have low testosterone, you might notice a reduction in muscle mass and strength.

This can manifest as difficulty in performing tasks that take physical strength, or a noticeable decrease in the size of your muscles. This could be a sign that your body is not producing enough testosterone.

Fat Distribution

Testosterone also plays a role in where the body stores fat. Men with low testosterone might notice an increase in body fat, especially in the chest area, leading to larger chest size.
Additionally, low testosterone could lead to a reduced ability to burn fat effectively. This might make it more difficult for you to lose weight despite regular exercise and a healthy diet.4

Bone Density

Bones also have a relationship with testosterone. It helps in keeping bones strong and dense. What are signs of low testosterone in males? If you have low testosterone, your bones might become more fragile and prone to fractures.
This decrease in bone density is often subtle and may not be noticeable until a sudden strain, bump, or fall causes a fracture.

Hair Loss and Body Hair

Testosterone is a key player in the natural hair production process.5
If you’re experiencing low testosterone levels, you might see less hair growth on your face and body.
Some men may even experience a decrease in the amount of hair on their heads, an effect similar to male pattern baldness.

Common Signs and Symptoms of Low Testosterone

While physical changes are one of the most common indications of low testosterone, there are other symptoms that can also indicate a decrease in hormone levels.


If you’re feeling unusually tired or facing difficulty getting out of bed even after adequate sleep, it could be an indicator of low testosterone.
This hormone plays a vital role in energy levels, and a decrease might lead to consistent feelings of tiredness and exhaustion.

Reduced Sexual Desire

Low testosterone can result in a drop in sexual desire or libido. You might find yourself less interested in sexual activities, which could affect relationships and mental well-being.

Mood Swings

If you’re experiencing unexplained mood swings, irritability, or increased stress, it might be due to low testosterone levels. Testosterone plays a role in maintaining mood and mental well-being.

Cognitive Difficulties

What are signs of low testosterone in males? Cognitive decline is often an overlooked symptom.
Some people might encounter difficulties with memory or concentration. Testosterone aids in cognitive functions, and a decrease in its level can lead to these problems.

Difficulty Achieving Erections

Testosterone stimulates sexual function and helps achieve an erection by triggering certain mechanisms in the body. Lower levels of this hormone might lead to difficulties in achieving or maintaining an erection.

Reduction in Testicle Size

A less common symptom, but one that can occur with low testosterone, is a reduction in the size of the testicles. This happens due to the integral role testosterone plays in testicular function.

How to Treat Low Testosterone

After learning about what are signs of low testosterone in males, it’s natural to wonder about possible solutions.
Treating low testosterone focuses on restoring the balance of this important hormone in the body, thereby reducing the signs and symptoms.
Below are some ways to manage low testosterone levels.

Testosterone Replacement Therapy

The most direct method of treating low testosterone is to replenish the hormone in your body through testosterone replacement therapy (TRT). This can be done via injections, skin patches or gels, or pellets implanted under the skin.
TRT can help in restoring muscle strength, improving mood and energy, and increasing sexual desire. But, you should avoid TRT if have prostate cancer, high red blood cell count, and heart or liver disease.6

Consult with your doctor or our team at Immortal Male to find out if TRT is the right option for you.

Healthy Lifestyle

Regular physical activity, especially resistance and high-intensity interval training, can boost testosterone production. 

Additionally, a balanced diet rich in lean proteins, healthy fats, fruits, vegetables, and whole grains can support health and hormone production.

Weight Management

As excess weight can affect testosterone levels, maintaining a healthy weight can be beneficial. This doesn’t mean severe calorie restriction but adopting a balanced approach to diet and exercise to achieve and maintain a healthy weight.

Adequate Sleep

Quality sleep is essential for hormone production, including testosterone. Establishing a consistent sleep routine can be beneficial for overall hormone balance.

Limit Alcohol and Avoid Illicit Substances

Alcohol consumption and the use of illicit substances can have a negative impact on testosterone levels. Limiting alcohol intake and avoiding drugs such as marijuana or anabolic steroids can help in keeping testosterone levels within healthy limits.

Stress Management

Chronic stress can negatively impact hormone balance, including testosterone. Techniques such as meditation, deep breathing exercises, yoga, and other stress-reducing activities can help manage stress levels.
