Maintaining normal testosterone levels is essential for overall male health. This hormone plays a central role not only in sexual function, but also in regulating mood, energy, motivation, and cognitive performance. Testosterone influences key neurotransmitters in the brain, including dopamine and serotonin, which are critical for emotional regulation and drive (Maggio et al., 2016).
Men with low testosterone may experience:
- Fatigue
- Reduced motivation
- Irritability, anxiety or low mood
- Decreased libido
- Diminished physical performance
Low testosterone can also affect anger and emotional control, as well as risk-taking and competitive behaviour. Supporting healthy testosterone levels through lifestyle factors — such as regular weight-bearing exercise, adequate sleep, stress management, and balanced nutrition — can play a vital role in maintaining overall mental well-being and vitality.
Testosterone can be measured through a simple blood test, ideally taken between 8–9am, when levels naturally peak. Where appropriate, testosterone can be safely supplemented back to normal physiological levels, which may help relieve symptoms and support overall health. Please make sure that you are monitoring your levels when supplementing and getting your medicines from a safe health care professional. Many trainers and gyms sell different hormone aids, these are not regulated and should be avoided for safety. Taking too much testosterone can impact red blood cell production, prostate size and mood negatively. It’s also important to remember that supplementing your testosterone in your reproductive years (before you have had your children) can lead to infertility.
