Men do not always talk openly about changes in their hormone levels. Even when something feels different, it may be easier to blame age, work pressure, or a busy lifestyle.
A gradual decline in sexual desire, persistent tiredness, mood changes, or reduced muscle strength may seem like a normal part of getting older.
But what happens when these symptoms continue for months and begin affecting everyday life?
Could low testosterone be contributing to these changes? And can hormone therapy help?
Testosterone levels generally decline gradually with age. However, not every man experiences symptoms, and aging alone does not mean testosterone replacement therapy is necessary.
When a man has symptoms consistent with testosterone deficiency and repeatedly low testosterone levels, medical treatment may be considered.
Understanding andropause symptoms in men is the first step toward identifying whether hormonal changes or another health condition may be responsible.
If you are experiencing persistent fatigue, reduced libido, or changes in mood, a personalized hormone assessment can help clarify the possible causes.

What Is Andropause in Men?
Andropause is a term commonly used to describe age-related hormonal changes in men, particularly declining testosterone levels.
It is sometimes called male menopause, although this comparison can be misleading.
Unlike female menopause, which involves a major hormonal transition associated with the end of menstrual periods, testosterone levels in men generally decline gradually over time.
Not every man develops symptoms or clinically significant testosterone deficiency.
When testosterone levels are consistently below the appropriate reference range and accompanied by relevant symptoms, a doctor may diagnose testosterone deficiency or male hypogonadism.
Age is only one possible contributing factor.
Other factors associated with low testosterone may include:
- Obesity and metabolic health conditions
- Type 2 diabetes
- Certain medications
- Sleep disorders
- Pituitary or testicular conditions
- Chronic illness
The NHS guidance on male menopause explains that symptoms commonly attributed to andropause may also be caused by stress, anxiety, depression, and other health problems.
This is why a medical assessment is important before assuming that testosterone is responsible.
What Are the Common Symptoms of Andropause?
Symptoms associated with testosterone deficiency can develop gradually.
Some men notice changes in sexual health first, while others become concerned about fatigue, mood, or physical performance.
However, these symptoms are not specific to low testosterone and may have several possible causes.
1. Low Energy and Persistent Fatigue
Feeling tired occasionally is normal, particularly during stressful periods.
However, persistent fatigue that affects daily activities may warrant medical evaluation.
Men with testosterone deficiency sometimes report:
- Reduced energy throughout the day
- Lower motivation
- Reduced physical stamina
- Difficulty maintaining usual exercise performance
- A general feeling of tiredness
Low testosterone is one possible explanation, but fatigue may also result from anemia, thyroid disorders, poor sleep, depression, or other medical conditions.
Important: Testosterone therapy does not consistently improve fatigue in men whose testosterone levels are normal.
2. Mood Changes and Irritability
Some men with low testosterone experience changes in mood or motivation.
These may include:
- Increased irritability
- Persistent low mood
- Reduced motivation
- Difficulty concentrating
- Changes in overall wellbeing
However, mood symptoms can also be related to psychological stress, relationship difficulties, anxiety, depression, or sleep problems.
Although testosterone treatment may improve some mood-related symptoms in men with confirmed deficiency, it should not replace appropriate mental health assessment or treatment.
3. Low Libido and Changes in Sexual Health
Reduced sexual desire is one of the more characteristic symptoms associated with testosterone deficiency.
Some men may notice:
- Reduced interest in sexual activity
- Fewer spontaneous or morning erections
- Changes in erectile function
- Reduced sexual satisfaction
Testosterone plays an important role in sexual desire.
However, erectile dysfunction is not always caused by low testosterone.
Cardiovascular disease, diabetes, medications, psychological factors, and other conditions may contribute.
A medical evaluation can help distinguish hormonal causes from other possible explanations.
4. Reduced Muscle Mass and Strength
Testosterone contributes to maintaining muscle mass and supporting bone health.
Men with clinically significant testosterone deficiency may experience:
- Reduced muscle mass
- Lower physical strength
- Increased body fat
- Reduced exercise performance
- Lower bone density in some cases
These changes can also occur with normal aging, insufficient physical activity, inadequate nutrition, or chronic illness.
5. Reduced Bone Density
Long-standing testosterone deficiency may contribute to reduced bone mineral density.
In some men, this can increase the risk of osteoporosis and fractures.
Depending on medical history and risk factors, a doctor may recommend additional investigations to assess bone health.
At What Age Do Andropause Symptoms Start?
There is no specific age when andropause begins.
Testosterone levels tend to decline gradually as men get older, but the rate varies considerably.
Some men experience symptoms in midlife, while others maintain testosterone levels and sexual function without clinically significant problems well into older age.
Symptoms alone cannot determine whether testosterone deficiency is present.
A diagnosis requires both compatible symptoms and consistently low testosterone levels confirmed through appropriate testing.
Can Hormone Therapy Help with Andropause Symptoms?
Testosterone replacement therapy, commonly known as TRT, may help men who have confirmed testosterone deficiency.
Its purpose is to restore testosterone to an appropriate physiological range and improve symptoms associated with deficiency.
However, treatment outcomes vary.
TRT should not be viewed as a general anti-aging treatment or an energy booster for men with normal testosterone levels.
Can Testosterone Therapy Improve Low Libido?
Testosterone therapy can improve sexual desire in some men with confirmed testosterone deficiency.
Evidence suggests that sexual symptoms are among the areas most likely to improve with appropriate treatment.
However, testosterone therapy may not resolve sexual difficulties caused by stress, relationship concerns, cardiovascular disease, or other medical conditions.
Can Testosterone Therapy Improve Energy Levels?
Some men report improvements in energy and general wellbeing after treatment.
However, research findings are less consistent for fatigue and vitality than for sexual desire.
If low energy is caused by sleep apnoea, thyroid disease, anemia, or another condition, testosterone replacement may not address the underlying problem.
Can Testosterone Therapy Improve Mood?
Testosterone treatment may improve certain mood-related symptoms in men with confirmed deficiency.
However, it is not an established substitute for treatment of clinical depression or anxiety.
Persistent psychological symptoms should be assessed independently.
Can Testosterone Therapy Improve Muscle Strength?
In men with testosterone deficiency, treatment can improve lean body mass and may contribute to improvements in certain measures of physical function.
The extent of improvement varies, and regular exercise and appropriate nutrition remain important.
What Does the Medical Evidence Say?
The Endocrine Society’s clinical practice guideline recommends testosterone therapy for appropriately selected men with symptoms of testosterone deficiency and consistently low testosterone levels.
Research published in the New England Journal of Medicine also found improvements in sexual function among some older men with low testosterone, while benefits for vitality were less consistent.
The key is identifying whether testosterone deficiency is genuinely contributing to the symptoms.
How Do You Know If You Need Testosterone Replacement Therapy?
A proper diagnosis involves more than checking a single testosterone result.
Your doctor should consider your symptoms, medical history, medications, and other possible causes.
Step 1: Review Your Symptoms and Medical History
Your consultation may include questions about:
- Sexual desire and erectile function
- Energy levels and fatigue
- Sleep quality
- Mood and mental wellbeing
- Current medications
- Chronic medical conditions
- Weight and metabolic health
- Fertility plans
This information helps determine whether testosterone testing is appropriate.
Step 2: Check Testosterone Levels
Testosterone is generally measured through a morning blood test.
Because testosterone levels fluctuate, a low result usually needs confirmation with a second morning measurement.
Testing conditions may need to be adjusted for men with unusual sleep schedules.
Step 3: Investigate Possible Causes
Depending on the findings, a doctor may recommend additional investigations.
These can include luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, or other relevant tests.
In certain situations, free testosterone assessment may also be appropriate.
These investigations help distinguish between different causes of testosterone deficiency.
Step 4: Discuss Treatment Options
If testosterone deficiency is confirmed, your doctor can explain whether TRT is appropriate.
Treatment options may include testosterone gels or injections, depending on clinical suitability and availability.
Not every man with a low testosterone result requires immediate hormone therapy.
Lifestyle changes, treatment of underlying conditions, or further investigation may be recommended first.
Is Testosterone Replacement Therapy Safe?
Testosterone replacement therapy can be beneficial for appropriately selected men, but it also carries risks and requires monitoring.
Before starting treatment, a clinician should assess relevant medical conditions and discuss the potential benefits and risks.
Possible considerations include:
- Increased red blood cell count: Testosterone therapy can increase hematocrit, potentially requiring dose adjustment or treatment interruption.
- Acne and oily skin: Some men may experience skin-related side effects.
- Sleep apnoea: Testosterone therapy may be inappropriate in men with untreated severe obstructive sleep apnoea.
- Prostate health: Prostate-related assessment and monitoring may be appropriate depending on age, medical history, and risk factors.
- Cardiovascular health: A clinician should assess cardiovascular risk and discuss current evidence, including possible treatment-related risks, before prescribing TRT.
- Fertility: Testosterone therapy can suppress sperm production and may reduce fertility.
Does Testosterone Therapy Affect Fertility?
Yes. This is an especially important consideration for men who are planning to have children.
External testosterone can suppress the hormonal signals involved in sperm production.
As a result, TRT may significantly reduce sperm count and sometimes cause azoospermia, meaning no sperm are present in the semen.
Men who wish to preserve fertility should discuss this before starting treatment.
Alternative approaches may be considered by an appropriately qualified specialist.
How Long Does Testosterone Therapy Take to Work?
The timeline varies depending on the symptom being treated and individual response.
Some men notice changes in sexual desire within the first several weeks or months.
Changes in body composition and other physical outcomes may take longer.
Improvements are not guaranteed, and fatigue or mood symptoms may persist if another condition is responsible.
Regular follow-up is necessary to determine whether treatment is effective and whether continued therapy is appropriate.
Why Is Monitoring Important During Testosterone Therapy?
TRT requires ongoing medical supervision.
Follow-up appointments help assess:
- Changes in symptoms
- Testosterone levels
- Hematocrit and other relevant blood results
- Potential side effects
- Prostate-related considerations where appropriate
- Overall treatment response
A doctor may adjust the dose, formulation, or treatment plan depending on the findings.
The goal of testosterone replacement therapy is not to achieve the highest possible testosterone level. It is to treat confirmed deficiency while maintaining an appropriate balance between benefits and risks.
Can Andropause Symptoms Be Managed Without Testosterone Therapy?
Not every man experiencing fatigue, low libido, or mood changes needs testosterone treatment.
When symptoms are related to lifestyle or other health conditions, addressing those factors may help.
Potential approaches include:
- Maintaining regular physical activity
- Incorporating resistance training
- Improving sleep quality
- Managing excess body weight
- Eating a balanced diet
- Reducing excessive alcohol consumption
- Addressing stress and mental health concerns
- Managing diabetes and other chronic conditions
For some men, improvements in weight and metabolic health may also improve testosterone levels.
However, lifestyle measures may not correct testosterone deficiency caused by certain pituitary or testicular conditions.
A medical assessment can help identify the most appropriate approach.

Frequently Asked Questions About Andropause and Testosterone Therapy
There is no fixed age. Testosterone levels generally decline gradually as men get older, but not every man develops symptoms or clinically significant deficiency.
Possible symptoms include reduced sexual desire, fewer spontaneous erections, fatigue, mood changes, and reduced muscle mass. These symptoms can also have non-hormonal causes.
Men with testosterone deficiency may experience fatigue, but low energy alone does not confirm a hormonal problem. Sleep disorders, anemia, thyroid conditions, and other health issues should also be considered.
Low testosterone may contribute to changes in mood and motivation in some men. However, depression, anxiety, stress, and sleep problems can cause similar symptoms.
Testosterone therapy may improve sexual desire in men with confirmed testosterone deficiency. The response depends on individual circumstances and whether other factors are contributing to sexual symptoms.
Regular exercise, adequate sleep, weight management, and a balanced diet may help improve overall health and address some causes of reduced testosterone. They may not correct deficiency caused by an underlying medical condition.
Diagnosis generally requires relevant symptoms and consistently low testosterone levels, usually confirmed through two separate morning blood tests. Additional investigations may be needed.
Some improvements in sexual desire may appear within weeks or months, while changes in body composition can take longer. Results vary, and regular monitoring is necessary.
TRT may be appropriate for men with confirmed testosterone deficiency, but it can cause side effects and may be unsuitable for certain individuals. Medical assessment and ongoing monitoring are essential.
Yes. Testosterone therapy can suppress sperm production and reduce fertility. Men planning to have children should discuss alternative treatment strategies with a specialist before starting TRT.
No. Fatigue alone is not sufficient to diagnose testosterone deficiency. Appropriate medical evaluation and laboratory confirmation are important before considering treatment.
Not exactly. The term male menopause is commonly used, but men do not experience the same abrupt hormonal transition associated with female menopause. Testosterone generally declines gradually, and many men never develop clinically significant deficiency.
Take the First Step Towards Better Hormone Health
Feeling unlike yourself can be frustrating, especially when changes in energy, mood, or libido begin affecting work, relationships, or everyday activities.
However, these symptoms do not automatically mean you have low testosterone.
A proper medical assessment can help determine whether testosterone deficiency, another health condition, or a combination of factors may be contributing.
For men with confirmed deficiency, testosterone replacement therapy may improve certain symptoms when prescribed and monitored appropriately.
Understanding the cause of your symptoms is more important than starting treatment without a clear diagnosis.
