low Testosterone

Low testosterone affects approximately 2 out of every 10 men over 60. It highlights how common this condition, also known as male hypogonadism.

Low testosterone occurs when the body doesn’t produce enough of this vital hormone. Testosterone is crucial in maintaining various bodily functions, including muscle mass, bone density, and sexual health. When levels are too low, it can cause severe problems in your body.

Whether you’re personally affected by this condition or simply curious about it, we’ve covered most of the details regarding low T level’s symptoms, causes, and possible treatments.

What Is Low Testosterone (Male Hypogonadism)?

Low testosterone occurs when the testes don’t produce enough of the hormone. It can lead to symptoms like mood changes, decreased libido, and fatigue. However, low testosterone isn’t just a natural part of aging—it can affect men at any age.

Some men may experience physical changes like increased body fat and reduced muscle mass. Others may notice psychological changes such as depression or difficulty concentrating. Low libido and erectile dysfunction are also common symptoms.

What Does Testosterone Do?

The testosterone hormone is produced primarily in the testicles of men, and smaller amounts are released in women from ovaries and adrenal glands.

Testosterone plays a vital role in sexual development and reproduction. It stimulates the growth and development of male sex organs during puberty, including the penis, testes, and prostate. It also promotes sperm production and maintains libido or sex drive. In women, testosterone helps maintain healthy sexual function by increasing sensitivity to stimulation.

Testosterone also affects bone density by stimulating bone mineralization and growth. It helps prevent conditions like osteoporosis later in life. It is responsible for developing muscle mass and strength during puberty, so men typically have more muscle than women.

Testosterone is vital in mood regulation, cognitive function, memory enhancement, and sustaining energy levels. It can help improve concentration, focus, motivation, and confidence while decreasing fatigue and depression symptoms.

What Is A Low Testosterone Level?

According to the American Urological Association, healthy males have testosterone levels ranging from 300 to 1000 nanograms per deciliter (ng/dl). When the levels fall below the lower limit, it is a sign of low testosterone. Meanwhile, females have lower levels ranging from 15 to 70 ng/dl.

Testosterone levels are the highest during teenage years and subside with age then onwards. The following are the common symptoms of low testosterone-

  • Low energy: One of the most common symptoms of low testosterone is fatigue and a lack of energy. It can make you constantly feel tired and drained.
  • Decreased libido: Testosterone plays a crucial role in sexual function. Low levels can lead to reduced sex drive or difficulty achieving and maintaining erections.
  • Mood changes: Hormones have a significant impact on our emotions. Testosterone aids in stress relief and its lower levels can contribute to feelings of depression, irritability, and even anxiety.
  • Reduced muscle mass: Testosterone helps build and maintain muscle mass. Low levels make it harder to gain or maintain muscle strength.
  • Increased body fat: Along with decreased muscle mass, low testosterone is often associated with increased body fat, specifically around the abdomen.

Who Does Low Testosterone (Male Hypogonadism) Affect?

The synthesis of testosterone gradually decreases with aging. Low testosterone is usually a concern for men over the age of 60. Some men may have a genetic predisposition to lower hormone production. In contrast, others may develop the condition due to certain medical conditions or lifestyle choices.

It also affects individuals across various age groups. It’s not just something older men experience; it can also affect young men. Many people mistakenly believe that only older individuals are affected by low testosterone, but that’s simply not true.

Symptoms and Causes of Low Testosterone in Men

The symptoms of low testosterone commonly include fatigue, reduced sex drive, or even erectile dysfunction, leading to infertility. Obesity decreases muscle mass and strength, and mood changes such as irritability or depression may also concern people with testosterone levels. Some men may also experience hot flashes or difficulty concentrating.

Symptoms Of Low Testosterone In Children

Children with low testosterone may exhibit delayed puberty or incomplete development of sexual characteristics. These symptoms can be concerning for parents and caregivers, as they may indicate an underlying medical condition that needs to be addressed.

  • Delayed Onset Of Puberty: It typically occurs around 12. Boys with low testosterone may also grow slower than their peers, resulting in shorter stature. These children may show poor muscle development and reduced strength.
  • Incomplete development of sexual characteristics: They may have smaller than average testicles or lack facial and body hair growth. They may also experience a delay in deepening their voice, which indicates that puberty is not progressing as it should.

It’s important to note that these symptoms can vary from child to child and may not always be obvious. Some children with low testosterone might show no external signs at all. Therefore, if there are concerns about a child’s development and if any of these symptoms are present, it’s essential to consult with a healthcare professional for further evaluation and diagnosis.

Causes of Low Testosterone

The most common cause is aging. Our bodies naturally produce less testosterone as we grow older. That’s why this condition is most prevalent among people above 60.

The condition of low testosterone levels in an individual can be further classified into two categories: primary male hypogonadism and secondary male hypogonadism.

Causes Of Primary Male Hypogonadism

Primary male hypogonadism is when your gonads, i.e., the glands responsible for producing sex hormones, are not releasing the required amount of testosterone in your body.

Here are three key factors that can contribute to primary male hypogonadism:

  • Congenital Disorders

    Some individuals are born with genetic conditions that affect their reproductive system. Conditions like Klinefelter syndrome or undescended testicles can result in low testosterone levels from an early age.

  • Testicular Injury or Infection

    Trauma or infection in the testicles can disrupt normal functioning, leading to low testosterone production. It could occur due to accidents, sports injuries, or illnesses like mumps.

  • Medical Treatments

    Certain medical treatments, such as radiation therapy or Chemotherapy for cancer treatment, long-term use of opioids for pain management, and corticosteroids for inflammation, can damage the testicles and reduce testosterone production.

Causes Of Secondary Male Hypogonadism

Secondary male hypogonadism occurs when there is a problem with the hypothalamus or pituitary gland.

These glands are responsible for signaling the testes to produce testosterone. One common cause of secondary male hypogonadism is a pituitary gland or hypothalamus tumor. These tumors can disrupt the normal production of hormones and lead to low testosterone levels.

Another possible cause is a genetic disorder called Kallmann syndrome, which affects the development of reproductive hormones and can result in delayed or absent puberty.

Other factors contributing to secondary male hypogonadism include certain medications, such as opioids or steroids, and chronic illnesses, such as kidney disease or obesity.

Excess body fat can disrupt hormonal balance and interfere with testosterone production. Men with higher body fat percentage are more likely to have low levels of testosterone compared to those who maintain a healthy weight. Alcohol abuse and high levels of stress can also disbalance hormone production.

Diagnosis and Tests

There are several diagnostic methods available that can give insights into the extent of the problem –

  1. Blood Tests: These are commonly used to measure hormone levels, including testosterone. A blood sample is taken and analyzed in a laboratory to assess the amount of testosterone present.
  2. Physical Examination: A thorough physical examination can provide valuable insights into any physical symptoms associated with low testosterone. The doctor may examine your genitalia, check for signs of hair loss or breast enlargement, and evaluate your overall muscle mass and strength.
  3. Symptom Assessment: It’s important to discuss any symptoms you’re experiencing with your healthcare provider. They will consider physical and emotional changes that could be attributed to low testosterone.
  4. Medical History Review: The signs of low testosterone may be hidden in some ailment of your past. Your doctor may review your medical history to identify potential risk factors or underlying conditions contributing to low testosterone levels.

Management and Treatment

Lifestyle changes can be one suitable option for reclaiming the vitality and restoring hormonal balance.

You can choose a healthier lifestyle by sleeping well and maintaining a balanced diet. You must also avoid excessive alcohol consumption and quit smoking, as it can positively impact hormone levels.

Testosterone replacement therapy (TRT) is an option for those with clinically low testosterone levels who require medical help. TRT involves introducing synthetic testosterone into the body through injections, patches, or gels. It helps restore hormone levels to normal and alleviate symptoms such as fatigue, decreased libido, and muscle weakness.

It’s important to note that TRT should always be prescribed by a qualified doctor who will monitor your progress closely. Regular blood tests may be conducted to ensure that hormone levels are optimized without causing any adverse effects.

By effectively managing low testosterone through lifestyle changes or medical interventions like TRT, individuals can experience significant improvements in their quality of life. However, it’s essential to understand that every person’s response to treatment may vary.

Side Effects Of Testosterone Replacement Therapy

One common side effect of TRT is acne. Increased testosterone levels can stimulate oil production in the skin, leading to breakouts. While this may not be a significant concern for everyone, it can be bothersome for those already prone to acne.

Fluid retention or swelling in the ankles and feet might occur as testosterone may cause the body to retain sodium and water. It’s essential to monitor any changes in swelling and report them to your healthcare provider.

In some cases, TRT may also lead to an increase in red blood cell count. It may increase the risk of blood clots or stroke. Regular monitoring of blood counts is essential during TRT.

Lastly, mood changes and irritability have been reported as side effects of TRT.

While these side effects are possible with TRT, it’s important to remember that not everyone will experience them. Your healthcare provider will closely monitor you throughout treatment and adjust as needed.


To effectively safeguard against the potential drawbacks of testosterone replacement therapy, you must focus on prevention strategies that can help minimize the side effects.

Regular exercise helps in weight management and boosts testosterone production naturally. Engaging in activities like weightlifting, resistance training, and high-intensity interval training (HIIT) can positively impact testosterone levels.

Chronic stress can lead to hormonal imbalances, including low testosterone. Finding healthy coping mechanisms like meditation or yoga can help deal with stress and promote overall well-being.

Ensuring adequate sleep is crucial for hormone regulation. Seven to eight hours of sound sleep each night supports optimal hormone production.

In your daily meals, adopt a balanced diet rich in nutrients, including lean meats, fish, whole grains, fruits, and healthy vegetables.
