Low testosterone doesn’t always manifest in obvious ways as people might expect. For some men, it starts with feeling unusually tired and not able to do hard physical work. For many other men, common symptoms include changes in mood, weight gain, or a drop in sex drive. Since many of these signs overlap with everyday stress or ageing, it’s easy to miss what’s really going on.
Testosterone plays a role in everything from bone health to memory. So when levels fall too low, the effects can be seen across many aspects of life. Low testosterone is sometimes linked to a medical issue, and sometimes it’s part of ageing. In this blog, we’ll explain what low testosterone is, what causes it, what to look out for, and how it can be treated.
Synopsis
What Is Low Testosterone?
Testosterone is a hormone that is produced in the testicles. It is commonly associated with puberty and sexual function. But it also plays an important role in things like muscle strength, bone health, mood, and overall energy. As men get older, it’s normal for testosterone levels to drop, but in some cases, the dip is more than it should be, and that’s a cause for concern.
Low testosterone in men is also termed male hypogonadism. It means the body isn’t producing enough of the hormone. Doctors usually consider it low when blood testosterone levels fall in the range of 250-300 nanograms per decilitre (ng/dL) or lower. If someone has low levels but no real symptoms, treatment may not be necessary. On the other hand, if the man has borderline low levels and feels constantly tired or has other issues, he might still need a proper check-up.
Common Low Testosterone Symptoms
Lower levels of testosterone can show some or all of the signs discussed below, depending on the drop. It’s important to understand that it often affects multiple parts of life, and the signs can build up slowly over time. Here are some common symptoms of low testosterone:
1. Low energy levels
Many men feel tired even after a full night’s sleep. Physical work starts to feel more exhausting, and there’s a constant sense of fatigue that doesn’t go away easily.
2. Drop in sex drive
A noticeable reduction in interest in sex is one of the more common symptoms. Some men may also find that sexual activity doesn’t feel as satisfying as before.
3. Erection issues
Testosterone doesn’t directly cause erections, but it supports the process. Men with low levels may notice weaker or less frequent erections, especially during early mornings.
4. Mood changes
Lower testosterone can make men feel irritable, low, or mentally dull. Some also report feeling less motivated or confident without understanding why.
5. Muscle loss or weakness
Despite regular activity, muscles may feel softer or shrink over time. Strength training results may slow down, even with effort.
6. Weight gain, especially around the belly
Excessive fat around the abdomen is common in individuals with lower testosterone levels. Some men notice that their body shape changes even if their diet hasn’t. Gynaecomastia is also seen in some men where there’s an excess development of breast tissue.
7. Poor sleep quality
Some men struggle to fall asleep or stay asleep. In other conditions, like sleep apnoea, it may also worsen.
8. Reduced memory or concentration
For some men, it may become harder to focus and remember small details. Staying mentally sharp during work or conversations can also become difficult.
Low Testosterone Causes
There isn’t just one reason why testosterone levels fall. In many men, it’s a mix of age, health conditions, and lifestyle habits. Here are some common causes of low testosterone:
1. Ageing
Testosterone levels naturally start to decline after the age of 30. For some men, the drop is slow and steady. But for some men, it’s more noticeable.
2. Injury to the testicles
Damage due to accidents, infections like mumps, or surgery in that area can affect hormone production.
3. Problems with the pituitary gland
This small gland in the brain regulates the amount of testosterone produced by the testicles. Tumours, head injuries, or certain diseases can disturb this balance.
4. Obesity
Excess body fat, particularly around the abdomen, is associated with lower testosterone levels. Fat tissue can convert testosterone into another hormone. This can lead to further imbalance in the hormones.
5. Chronic illnesses
Conditions like diabetes, kidney disease, liver disease, and HIV can all interfere with testosterone production.
6. Alcohol and smoking
Heavy drinking or regular smoking over time can reduce hormone levels and affect testicular function.
7. Sleep disorders
Issues like sleep apnoea are linked to lower hormone levels. Poor sleep also affects the body's ability to regulate testosterone naturally.
Treatment For Low Testosterone
Treatment depends on how low the T levels are, what’s causing it, and how much it’s affecting daily life.
1. Lifestyle changes
Losing excess weight, eating a balanced diet, sleeping well, and exercising regularly can help boost natural testosterone production. These changes also improve energy, mood, and overall health. Not everyone needs hormone therapy; in many cases, small changes make a big difference.
2. Testosterone Replacement Therapy (TRT)
If levels remain low and symptoms are strong, doctors may suggest TRT. It can be given as:
-
Skin gels or patches
-
Injections (weekly or monthly)
-
Tablets placed inside the mouth (buccal tablets)
-
Implants under the skin
3. Regular monitoring
TRT isn’t a quick fix. Blood tests are done regularly to keep hormone levels in check and to watch for side effects like increased red blood cells or prostate issues.
4. Addressing underlying causes
If lower levels of testosterone are due to another condition like diabetes or pituitary problems, managing the root issue can help bring hormone levels back up naturally.
Conclusion
Reduced levels of testosterone can quietly affect how you feel, think, and function. It’s not always easy to spot, especially when symptoms are dismissed as stress or ageing. But if tiredness, low sex drive, or changes in mood and strength have become a pattern, it’s important to get it checked. A proper diagnosis can help you understand what’s going on and what steps to take next.
