What is Testosterone?

Testosterone is a hormone and androgen that is mainly classed as a ‘male’ hormone but women’s ovaries also produce it but in smaller amounts. It is a key component in bodily functions such as libido, strength & muscles, mood and energy levels. When this hormone is not in the average levels, it can produce symptoms relating to mood and physical health but also plays a large part in fertility changes too.

Why is Checking Testosterone Important?

Testosterone levels do tend to decreased as you age and typically starting to gradually get lower from the age of 30. This is usually a slow process and you won’t notice any immediate symptoms. Checking your levels can help you determine if it is the cause or being caused by another health condition, the cause of early or delayed puberty, or if you need to make lifestyle changes.

What Can Affect Testosterone Levels?

Testosterone levels naturally decline with age. However, certain lifestyle factors can affect them too, including:

  • Increased stress or high cortisol levels
  • Alcohol consumption levels
  • Lack of sleep
  • Too much or too little exercise
  • Smoking
  • Being overweight or obese
  • Diet habits including processed foods and sugar

It is also equally important to monitor the effectiveness of consistent intense exercise, as this can reduce your levels, leading to lower energy levels and fatigue.

Can Testosterone Be Increased Naturally?

Increasing testosterone levels can be naturally done by some lifestyle changes, including:

  • Limit alcohol intake
  • Ensure you’re getting a balanced diet with appropriate nutrition
  • Reduce processed foods
  • Get consistent, good-quality sleep
  • Weight management
  • Regular exercise and include strength training alongside aerobic exercise
  • Reduce stress levels

These are the main pointers to increase testosterone levels, however, there may be other health-related issues that may need to be considered in individual cases.

Is There a Best Time To Take A Testosterone Blood Test?

Testosterone levels naturally fluctuate throughout the day but any time of the day should be able to identify really high or really low levels. Testosterone is typically at its highest point between 7 am and 10 am, lower during the day and peaking again at night.
