Low Testosterone in Men: Symptoms and Treatment
Testosterone is an important hormone that supports male reproductive health, muscle development, bone strength, energy levels and sexual function. When the body produces less testosterone than required, a condition known as testosterone deficiency or hypogonadism may develop.
Low testosterone can affect men at different ages. Some may notice reduced sexual desire, tiredness or difficulty maintaining muscle mass, while others may experience mood changes, fertility concerns or erectile difficulties. However, these symptoms can also occur due to other health conditions, so proper medical evaluation is important.
What Is Low Testosterone in Men?
Testosterone is a hormone mainly produced by the testicles. It plays an important role in male sexual development, sperm production, muscle growth, bone density and red blood cell production.
Low testosterone occurs when the body consistently produces less testosterone than expected for an individual's age and health. It may develop because of problems affecting the testicles, pituitary gland or hypothalamus in the brain.
The condition can be temporary or long-term, depending on its underlying cause. It is also important to understand that having one low testosterone reading does not automatically mean a person has testosterone deficiency. A doctor considers symptoms, medical history and repeated blood test results before making a diagnosis.
Normal Testosterone Levels in Men
Testosterone levels vary throughout the day and may differ based on age, health, sleep, medication and laboratory testing methods.
For adult men, many laboratories use a reference range of approximately 300–1,000 ng/dL for total testosterone. However, the normal testosterone level in men can vary between laboratories, and the result should always be interpreted by a qualified doctor.
The American Urological Association uses a total testosterone level below 300 ng/dL as a reasonable cut-off to support a diagnosis of testosterone deficiency. However, the diagnosis also requires relevant symptoms or signs and consistently low readings on separate tests.
Testosterone levels are generally higher in the morning. Therefore, doctors usually recommend testing in the early morning and repeating the test on another day if the first result is low.
Low Testosterone Symptoms and Causes
Understanding the causes, recognising the symptoms and seeking timely medical advice can help men manage testosterone deficiency effectively.
Diagnosis and Management of Low Testosterone
A proper diagnosis involves reviewing symptoms, medical history, and blood test results to determine the best approach for individual patient care.
Common Symptoms of Low Testosterone
The symptoms of low testosterone may develop gradually, making them easy to overlook. Some men experience sexual health concerns, while others notice changes in their physical strength, mood or general well-being.
Common low testosterone symptoms include:
- Reduced sexual desire or libido
- Difficulty achieving or maintaining an erection
- Persistent tiredness and low energy
- Reduced muscle mass and physical strength
- Increased body fat, particularly around the abdomen
- Decreased facial or body hair growth
- Mood changes, irritability or low motivation
- Difficulty concentrating
- Reduced bone density
- Fertility problems or reduced sperm production
Not every man experiences all these symptoms. Since several other conditions can cause similar changes, medical assessment and appropriate testing are necessary.
Causes of Low Testosterone in Men
Several medical conditions and lifestyle factors can affect testosterone production.
Some common causes include:
- Ageing: Testosterone levels may gradually decline with age, although significant symptoms should not automatically be considered a normal part of ageing.
- Obesity: Excess body fat is associated with lower testosterone levels and hormonal changes.
- Type 2 diabetes: Metabolic conditions may be linked to testosterone deficiency.
- Testicular problems: Injuries, infections, certain medical treatments or damage to the testicles can affect hormone production.
- Pituitary gland disorders: Problems with the pituitary gland or hypothalamus can interfere with the signals that regulate testosterone production.
- Chronic illnesses: Certain long-term health conditions can affect hormone balance.
- Medications: Some medicines, including long-term opioid use and certain steroid treatments, may affect testosterone levels.
- Sleep-related problems: Poor sleep and sleep disorders may contribute to hormonal changes.
Low Testosterone in Young Men: Why It Happens
Low testosterone is not limited to older men. Young men can also experience testosterone deficiency due to medical conditions, lifestyle factors or hormonal disorders.
Possible causes include testicular injuries, genetic conditions, obesity, pituitary gland disorders, chronic illnesses and certain medications. Excessive use of anabolic steroids can also interfere with the body's natural hormone production.
Young men may notice reduced sexual desire, fatigue, difficulty building muscle, mood changes or fertility concerns. These symptoms should not be ignored or treated with over-the-counter testosterone boosters. A urologist or endocrinologist can evaluate the symptoms, identify possible causes and recommend appropriate care. Early assessment is particularly important when fertility is a concern.
How Low Testosterone Is Diagnosed
A proper diagnosis involves reviewing symptoms, medical history and blood test results. A doctor may recommend the following investigations:
- 1. Testosterone Test: A blood test measures total testosterone levels, generally performed in the early morning under fasting conditions. If low, a repeat test on a separate morning is recommended.
- 2. Additional Hormone Tests: Luteinising hormone (LH) and follicle-stimulating hormone (FSH) tests help identify if the problem originates in the testicles or the brain.
- 3. Other Blood Investigations: Assessing thyroid function, prolactin, blood sugar, blood count or other indicators based on patient symptoms.
- 4. Medical History and Physical Examination: Reviewing medication use, previous illnesses, sleep patterns, sexual health and fertility concerns.
Foods and Lifestyle Habits That Support Healthy Testosterone Levels
A balanced diet and healthy lifestyle can support overall hormonal and reproductive health. However, no specific food can reliably cure testosterone deficiency.
Nutritious foods that form part of a healthy diet include eggs, fatty fish (salmon and sardines), nuts and seeds, leafy vegetables, whole grains, and fresh fruits.
Along with healthy eating, lifestyle habits include regular exercise (including strength training), maintaining a healthy body weight, getting sufficient sleep, managing stress, avoiding smoking/limiting alcohol, and avoiding anabolic steroids.
Treatment Options for Low Testosterone
The right low testosterone treatment depends on the cause, severity of symptoms, test results, age and fertility plans.
Treatment approaches include managing underlying medical conditions, lifestyle modifications, medication review, and hormonal treatment (such as testosterone replacement therapy). Self-medication should be avoided as it can lead to unwanted side effects.
Testosterone Replacement Therapy and Injections: Benefits and Risks
Testosterone replacement therapy (TRT) may be recommended for men with confirmed deficiency, utilizing gels, injections, or other formulations. Injections help restore hormone levels, improving sexual desire, energy, or muscle mass.
However, risks and side effects include reduced sperm production/fertility, increased red blood cell count, acne, fluid retention, breast tenderness, and sleep-related breathing changes. Men planning children should discuss fertility-preserving options first.
Complications of Leaving Low Testosterone Untreated
When genuine testosterone deficiency remains untreated, potential complications include reduced muscle mass and physical strength, decreased bone density (osteoporosis risk), persistent sexual health problems, reduced fertility, mood changes, increased body fat, and unexplained anaemia. Timely diagnosis can help reduce these impacts.

Frequently Asked Questions About Low Testosterone
Early signs may include reduced sexual desire, tiredness, low energy, mood changes and difficulty maintaining muscle mass. Some men may also experience erectile difficulties. A blood test and medical evaluation are needed to confirm the cause.
Many laboratories use a reference range of approximately 300–1,000 ng/dL for adult men. However, the range varies by laboratory and testing method. Doctors interpret the result along with symptoms and other clinical findings.
Yes. Low testosterone in young men can occur due to obesity, testicular injuries, genetic conditions, pituitary disorders, chronic illnesses or certain medications. Persistent symptoms should be evaluated by a qualified doctor.
Doctors usually assess symptoms and medical history and recommend an early-morning testosterone blood test. If the result is low, a repeat test on a separate day is generally needed. Additional hormone tests may help identify the underlying cause.
Maintaining a healthy weight, exercising regularly, getting sufficient sleep, eating a balanced diet and managing stress can support overall hormonal health. However, these habits may not correct testosterone deficiency caused by an underlying medical condition.
Eggs, fatty fish, nuts, seeds, leafy vegetables and whole grains provide nutrients that support general health. No single food is proven to cure low testosterone, so a balanced diet is more useful than relying on specific foods.
Testosterone injections may be appropriate for men with confirmed testosterone deficiency when prescribed and monitored by a doctor. Possible side effects include increased red blood cell count, acne and reduced sperm production. Regular follow-up is important.
Yes. Low testosterone may be associated with reproductive problems, and testosterone replacement therapy can further reduce sperm production. Men planning to have children should discuss fertility goals with their specialist before starting treatment.
It depends on the underlying cause. If low levels are linked to a reversible condition, addressing that condition may improve testosterone levels. Other causes may require long-term management and regular medical monitoring.
A qualified urologist or endocrinologist can evaluate symptoms, arrange relevant tests and recommend suitable treatment. If you are experiencing persistent symptoms, consult a specialist at a recognised healthcare centre such as Nephron Kidney Centre for medical guidance.
