Why check
Male Hormone levels?

Our male hormone blood test offers a comprehensive check of all the key male hormones. This men’s hormone test measures the levels of LH (luteinising hormone), FSH (follicle-stimulating hormone), SHBG (sex hormone-binding globulin) as well as three different testosterone measures; total testosterone, free testosterone (calculated) and FAI (free androgen index).

Testosterone is the primary male hormone and as men age the levels of testosterone decrease. But age is not the only reason for a decline in testosterone levels, over training can also reduce levels.

Understanding your levels of these key biomarkers and tracking them over time can help you manage symptoms such as a lack of energy, fatigue, loss of libido, weight gain and poor sports performance.

What are male hormones?

The main male hormone in blood is testosterone. This male hormone effects multiple functions in the body. For example, testosterone supports body composition and maintains haemoglobin levels to carry oxygen round the body. Conversely suboptimal levels of testosterone will result in reduced libido and fatigue.

Total testosterone is the most common biomarker measured and includes both bound and free testosterone within the body. The majority of testosterone is bound, predominately to the transport protein sex hormone binding globulin (SHBG). So it is possible to calculate free testosterone knowing total testosterone and SHBG levels.

Measuring the hormones that control testosterone production is also extremely important. The main control hormone is luteinising hormone (LH) which is produced by the pituitary gland in the brain. The pituitary gland also produces the hormone prolactin which can reduce the production of LH and hence testosterone if it becomes too high.

Measuring testosterone in isolation therefore does have some limitations. Whilst measuring control hormones such as luteinising hormones and other transports proteins will provide a fuller picture.

Our male hormone test kit also assesses your thyroid function. The thyroid gland is important for the metabolism i.e. how fast the cells in your body work. Imbalances in thyroid hormones like TSH or thyroxine can cause symptoms like mood changes, weight loss or gain as well as muscle and bone pain.

If your testosterone levels are lower than expected for your age, you will receive advice from an endocrinology specialist indicating the possible cause in the context of the other hormones measured. Providing as much information as possible about exercise levels and diet is very helpful to help our doctors provide an informed & personalised response.

How Do Male Hormones
Impact Wellbeing?

Sports Performance

The male hormone testosterone has a vital role in sports performance, particularly because it is essential for strong bones, lean muscle, and faster recovery times. However, over training can result in low testosterone levels resulting in a myriad of symptoms, such as:

  • Fatigue
  • Low or no sex drive
  • Insomnia
  • Difficult to build muscle mass
  • Fertility issues
  • Anxiety and/or depression
  • Slower recovery times post-training

Therefore, finding out early that your testosterone levels are low can help you make changes to your training schedule to ensure you have enough recovery time.

Mood And Energy

Testosterone levels naturally decline with age, at a rate of approximately 2% per year. Men who have low testosterone levels may experience fatigue and mood swings.

However, other hormones can play a role such as cortisol, the body’s main stress hormone.

Cortisol levels rise when the body is under stress resulting in symptoms such as depression and anxiety.  High cortisol levels  can also lead to disrupted sleep resulting in fatigue.

Low cortisol level can result in a dip in energy levels and leave you feeling weak and tired.

Imbalances in thyroid hormones can also cause many of these symptoms and can affect both your energy levels and your moods.

The male hormone test will help you gain an insight into your hormone levels and areas of your lifestyle that may need changing to improve them.

Dr Nicky Keay
the Experts Opinion

“Male hormone networks influence a man’s overall wellbeing, not just fertility. To identify what and where any dysregulation of this network is occurring, the control hormones, FSH and LH are measured, alongside testosterone and hormones which can impact this hormone network including prolactin and cortisol. Once any issues have been identified, this enables you to put strategies in place to improve your health. This could be changed to your lifestyle, reducing stress, taking more exercise, and having a better diet. Over-exercising and/or under fuelling can also cause disruption of the male hormone network as this increases stress in the body which disrupts male hormone networks.

Thyroid disorders can result in mood changes, weight gain or loss and muscle cramps. So, including thyroid biomarkers within this test gives a full and rounded picture of your overall hormone health and identifies the cause of any symptoms and how to address these.”

Frequently asked questions

 Here are some of the most frequently asked questions. If you need anything else try our help section.

  • What are the main male hormones involved in fertility?

    Hormones have key roles in male fertility, particularly follicle-stimulating hormone (FSH), luteinising hormone (LH), and testosterone. FSH and LH work by stimulating the testes to produce testosterone which is vital for sperm production.

    Therefore, conditions that cause low FSH or LH levels in men can result in sperm production being low or non-existent as well as low levels of testosterone in the blood.

    Our male hormone check measures your levels of FSH, LH, and testosterone so you can identify any potential fertility issues.

  • What are the symptoms of hormone imbalance in males?

    An imbalance in hormones in men can lead to:

    • Low libido
    • Lack of energy
    • Poor sleep
    • Weight gain
    • Erectile dysfunction
    • Low mood
    • Inability to build or maintain muscle mass
    • Decreased bone density
  • Can exercise increase testosterone levels?

    Studies have found that there is a short term boost to testosterone levels after exercise.

    The University of Southern California found that testosterone levels are elevated immediately after exercise for anything from 15 minutes to an hour. The study however, found that this elevation doesn’t last beyond this period.

    If you have low levels of testosterone, exercise alone will not resolve the issue. But it’s possible that exercise could help you maintain normal levels if you’re borderline.

    Research suggests that high-intensity workouts, in particular, are the most effective for boosting testosterone levels.
