Low Testosterone Signs


Testosterone is a hormone made mostly by men’s testicles. Women have it too, but men have more. Testosterone affects a man’s physical and mental health. It can even change fertility, sex drive, muscle size, body fat, and feelings.

Low-T means testosterone levels are low. It can lead to problems like no sex drive, being tired, feeling bad, losing muscle and gaining fat. Low-T is often caused by aging. Not all men have the same signs of Low-T, and some men have different signs at different times.

It is important to notice changes that don’t seem normal. If there are several signs or one sign lasts longer than 3 months, it is time to get tested for Low-T.

Symptoms of Low Testosterone

Low testosterone levels can create a variety of physical, mental, and emotional symptoms. These can include:

  • Reduced libido.
  • Issues with erections.
  • Low energy.
  • Loss of muscle mass.
  • Unexpected weight gain.
  • Depression.
  • Irritability.
  • Trouble focusing.

In this article, we’ll delve deeper into the symptoms of low testosterone.

Low Libido

Low libido is a lack of interest in sex. It can be caused by low testosterone levels in men. This can lead to issues like trouble with erections, difficulty achieving orgasm, and decreased pleasure during sex.

Physical changes may also be present. If they are, see a doctor. Meanwhile, mental effects such as depression, guilt, or shame can also occur. Psychological counseling can help with these mental impacts.

Erectile Dysfunction

Erectile dysfunction is a widespread symptom of low testosterone. It causes difficulty in achieving and keeping an erection and can decrease sexual desire. Reasons for this can be hormonal changes, age, mental health issues, or medical conditions like diabetes or hypertension.

Low testosterone can disrupt hormone production, essential for arousal. It can also decrease sperm count and raise the risk of prostate cancer. Treatment options depend on the cause and may include:

  • Hormone replacement
  • Lifestyle changes such as diet, exercise, and stress management.


Tiredness is a common symptom of low testosterone. This can impact energy levels, making it hard to stay alert and to get enough sleep. People may feel weak and tired, even after resting. Other signs of fatigue include trouble concentrating, low motivation, and memory issues.

If you believe low testosterone is causing your fatigue, it is important to see a doctor.

Low Energy

Low energy is linked to low testosterone in men. Studies show that those with low testosterone feel weaker, sluggish, and fatigued. Even a little physical effort could make them exhausted. They may also have problems sleeping, which worsens the fatigue. Low testosterone can also cause confusion and difficulty focusing.

If you have any of these symptoms, talk to your doctor about testing for low testosterone.

Muscle Loss

Low testosterone levels can cause a decrease in muscle mass and strength. This can be especially visible if the drop happens quick due to an endocrine system problem.

Signs of muscle loss from low testosterone include:

  • Smaller muscle mass compared to past body fat percentages.
  • Lack of power and strength in the gym.
  • Difficulty continuing physical performance at previous levels.

To reverse muscle loss associated with low testosterone, more than just hormone replacement is needed. Regular exercise, improved nutrition and supplementation are key for best results.

Weight Gain

Weight gain? It could be a sign of low testosterone in men. Testosterone helps the body use proteins, fats, and carbohydrates to make energy. When testosterone levels are low, the body may not have enough energy to burn fat, so it stores it. Research suggests men with lower testosterone often have more weight than those with regular levels.

Other signs of low testosterone can also lead to weight gain, like a slow metabolism, or limited muscle growth. Treating low testosterone can boost metabolism and muscle mass; which may help with weight loss.

Mood Swings

Low testosterone can cause huge mood changes – from feeling sad and tired to anger and irritability. Men with low testosterone may become snappy, depressed and demotivated, affecting their daily life and enthusiasm.

Lack of concentration and difficulty staying focused can also be caused by hormone imbalance. Symptoms of anxiety and depression may occur, needing extra treatment like counseling or medication for better wellbeing.

Causes of Low Testosterone

Men may suffer from low testosterone, with a range of symptoms. Knowing why testosterone is low can aid males in understanding their difficulties and making a plan. This writing looks at the various causes of low testosterone, from everyday habits to medical issues:

  • Everyday habits such as smoking, drinking alcohol, and lack of exercise.
  • Medical conditions such as obesity, type 2 diabetes, and HIV/AIDS.
  • Medications such as steroids, opiates, and certain antidepressants.
  • Age-related issues such as aging, a decrease in pituitary gland function, and a decrease in testicular function.


Aging is a main factor in low testosterone in men. After 30, levels of testosterone drop by 1% annually. Signs of low testosterone may appear in males as early as the late twenties or early thirties.

Injury or infection to the testicles, major stress on the body, some surgeries, and chronic illnesses like HIV/AIDS, diabetes, and some kidney diseases can also cause low testosterone. Medications, like opiate painkillers or steroids, may also lead to a drop in testosterone.


Obesity and being overweight can lead to lower testosterone levels in men. Fat cells directly suppress the testes, decrease SHBG production and reduce testosterone delivery to target tissues. Obesity is linked to metabolic syndrome and type 2 diabetes, which also leads to lower testosterone. Additionally, being overweight may cause testosterone to convert to estradiol (an estrogen) – this decreases testosterone availability.

Men who are obese or overweight should try to lose weight with a healthy diet and exercise. This will help improve overall health and potentially raise their testosterone levels.


Chronic stress can be a major cause of low testosterone. It could be due to:

  • Psychological tension lasting long
  • Demanding physical work or sickness
  • Poor diet or no physical activity
  • Low serum vitamin D or magnesium levels

Stress brings exhaustion and burnout, which can reduce testosterone in the body. To maintain healthy testosterone levels, we must find ways to manage stress and low moods. This could be done by making lifestyle changes, such as regular exercise or activities that bring enjoyment and relaxation. Techniques, like yoga and meditation, can help to reduce cortisol (the hormone made by the body under stress) and ensure proper testosterone balance.


Certain drugs can bring down testosterone levels. Anabolic steroids have the same structure as testosterone, and can stop natural testosterone production over time. Corticosteroids can disrupt hormones related to fertility and libido if taken for a long period. Chronic opioid use has been linked to low testosterone, due to decreased LH and FSH levels caused by decreased brain regulation. Lastly, drugs containing estrogen, such as those used for birth control or HRT, can lower testosterone in men, particularly if taken in higher doses than prescribed.


Injuries, like fractures and crushed bones, can bruise or swell the testicles. This can cause a drop in testosterone production. Nerve damage (spinal cord injuries), radiation exposure and high blood sugar levels (from sugary food or diabetes) can also lead to low testosterone.

Other medical conditions like

  • liver/kidney diseases
  • Klinefelter’s syndrome
  • pituitary gland issues
  • cancer treatments that affect hormones

can also cause low testosterone.


Certain diseases, conditions and lifestyle choices can lead to low testosterone. These include chronic kidney/liver disease, type 2 diabetes, and certain tumors. Obesity, unhealthy habits, and genes can also play a role in reducing testosterone production. The hypothalamus or pituitary glands may be affected by genetic abnormalities, especially with young men. Lastly, aging can contribute to diminishing levels, with poor diet and lack of exercise making it worse.

Diagnosis and Treatment

Testosterone levels can be low, resulting in a variety of symptoms. To diagnose, a blood test is needed. Treatment for low testosterone differs from person to person. Let us take a look at diagnosis and treatment for low testosterone:

Blood Test

To assess testosterone levels, a blood or saliva sample is needed. A morning blood sample is ideal, as this is when testosterone levels are highest. It’s important to consider other abnormalities present, and normal values for men and women may differ.

Also, doctors may suggest additional tests, such as

  • FSH/LH
  • Prolactin
  • IGF-1
  • Estrogen
  • Free testosterone
  • SHBG

might also be taken into account. Your doctor will explain how often tests should be done to check the success of treatment.

Hormone Replacement Therapy

Hormone Replacement Therapy (HRT) can be a helpful treatment for those suffering from low testosterone. It works to restore the natural balance of hormones in the body, particularly testosterone. This can improve symptoms such as fatigue, depression, and difficulty with sexual performance.

It may involve synthetic forms of testosterone to increase overall levels, or other hormones like estrogen or progesterone.

When thinking about HRT, talk to your doctor about medical history and potential risks such as stroke or heart disease. Sometimes lifestyle changes like exercise and healthy eating are recommended instead of HRT. In other cases, lifestyle changes can be combined with medication or HRT for better results. If your doctor suggests hormone therapy, be sure to follow instructions carefully.

Lifestyle Changes

To help Low Testosterone (Low-T) levels, certain lifestyle changes are key! Eating a balanced and nutritious diet is vital for optimal hormone production. Adjustments can also naturally boost testosterone:

  • Stress reduction
  • Exercising
  • Maintaining a healthy weight
  • Limiting alcohol
  • Sleeping well

Relaxation techniques like deep breathing and yoga can help maintain hormones. Massage and acupuncture can reduce stress and increase relaxation too. Herbal supplements like Saw Palmetto, Tribulus Terrestris, Ginseng or Horny Goat Weed could potentially improve low testosterone. However, always speak to your doctor first – they may not be suitable or interfere with existing meds.


Low testosterone levels can cause many symptoms. If you have signs such as decreased libido, erectile dysfunction, infertility, depression, or muscle loss, you should go to the doctor. Your doctor will check your hormones and make a treatment plan for you.

To improve your testosterone levels, you can make lifestyle changes. However, sometimes medical treatment with testosterone replacement therapy is the best solution. Doing this can give you more energy and better quality of life.
