Low testosterone and fatigue.
Are you feeling tired and low most of the time? Do you find it takes too much effort to do the things you used to enjoy? Your fatigue may be caused by low testosterone.
Why does low testosterone cause fatigue?
Low testosterone can also affect your ability to concentrate and bring feelings of apathy and lack of motivation.
Your fatigue levels may become chronic if your Testosterone levels fall low enough. You may experience feelings of extreme tiredness and be unable to do the things you used to do effortlessly.
When testosterone levels drop in men, their health can be affected in many ways, including:
- Fatigue
- Depression
- Low sex drive
- Loss of muscle mass
- Increased weight gain
Testosterone therapy can be very effective in improving your energy levels, lifting your mood, restoring your sense of well-being and improving your concentration.
The importance of testosterone and energy levels
Testosterone is a vital hormone in the male body, responsible for shaping many of the physical characteristics typically associated with masculinity. It belongs to a group of hormones known as androgens and is widely regarded as the most important male sex hormone due to its broad range of functions.
In men, testosterone is primarily produced in the testicles by specialised cells called Leydig cells, with a smaller amount also made by the adrenal glands. The body carefully regulates testosterone production through a system that starts in the brain. The hypothalamus signals the pituitary gland to release luteinising hormone (LH), which then travels through the bloodstream to the testes, prompting them to produce testosterone. This process operates as a feedback loop known as the hypothalamic-pituitary-gonadal axis, keeping hormone levels in balance.
Testosterone plays a key role in male health and development. During puberty, it drives the growth of male reproductive organs, deepens the voice, and promotes facial and body hair growth. It helps maintain muscle mass and bone strength throughout adulthood. Testosterone also influences sex drive and erectile function, supports emotional wellbeing, and affects energy levels and mental focus. It plays a role in fat distribution and how the body processes glucose and insulin. Most importantly, testosterone is essential for sperm production and male fertility.

More low testosterone symptoms.
Reduced sex drive.
Have you noticed a significant drop in your interest in sex? A reduced sex drive is one of the most common symptoms of low testosterone. You might feel less desire for intimacy or find it difficult to become aroused. This can be frustrating and may put strain on your relationship or self-esteem. Testosterone is the key hormone that fuels sexual desire in men — when levels are low, your body may simply not respond the way it used to.
Erectile dysfunction.
Struggling with weak or infrequent erections, or finding it harder to maintain them? Low testosterone can interfere with the natural processes that allow for strong and consistent erections. While other factors like stress, anxiety, or health conditions can contribute, testosterone is crucial for healthy sexual function. If you’re experiencing these changes alongside a loss of libido, low T may be the underlying cause — and help is available.
Loss of muscle and strength.
Are you finding it harder to maintain or build muscle, even with regular exercise? Testosterone is essential for muscle growth, strength, and physical endurance. When levels are low, your body’s ability to develop lean muscle diminishes, and you may also notice an increase in body fat — especially around the midsection. This physical change can lead to frustration and reduced motivation, creating a cycle that’s difficult to break.
Mood changes, iritability and depression.
Have you been feeling more irritable, anxious or down than usual? Testosterone doesn’t just affect the body — it also plays a role in emotional wellbeing. Low levels can contribute to mood swings, a sense of apathy, and in some cases, depression. If you’ve noticed a decline in your mental outlook or feel emotionally “flat,” low testosterone may be part of the picture. These mood changes can also affect relationships, work, and your overall quality of life.
Stubborn weight gain.
Is the weight around your belly becoming harder to shift, despite regular exercise or a healthy diet? Testosterone helps regulate how your body stores fat and builds muscle. When levels drop, metabolism slows down, making it easier to gain fat and harder to lose it — especially around the abdomen. Low T can also contribute to insulin resistance, which may make fat storage even more difficult to control.
