Improve Your
Testosterone Levels

Want to improve your health & wellbeing? Forth gives you insight into your body’s key biomarkers. By tracking essential markers overtime you can build a picture of your own unique self and discover how your body responds to the changes you make so you can reach your personal best.

Dr Nicky Keay
the Experts Opinion

Testosterone is a sex steroid hormone found in both men and women, although higher levels in men. Levels in both men and women decline from middle age. Informing yourself of your testosterone level can help you to understand if your value is as expected, low or high for your age and biological sex. Your result can then be considered in the context of any symptoms you are experiencing, and tailored advice given to address any issues identified. This might include resistance type exercise to support testosterone levels, and/or reviewing dietary intake matches demands from exercise training and/or if sufficient recovery being taken.

Why measure
Testosterone levels?

Our home testosterone test measures total testosterone which is a combination of free and bound testosterone. Testosterone is an essential hormone integral to multiple functions in the body including energy, bone health, mood, libido and muscle growth. Our convenient testosterone test kit will identify if your levels require improvement. 

When to take This test

Testosterone levels are at their peak first thing in the morning, so it's best to collect a sample for the testosterone test between 8am - 10am.

In Women

Our testosterone test isn’t just for men. Women also produce testosterone in smaller amounts and it is involved in female sex drive and the health of the bones, breasts, vagina, and menstruation.

Low levels of testosterone in women can cause missed or irregular periods, osteoporosis, decreased libido, vaginal dryness, and infertility.

High levels of testosterone in women can be caused by Polycystic Ovary Syndrome (PCOS).

Testosterone and Exercise

Some exercises initially increase testosterone levels but this is usually only for a brief period. However, there is a fine balance needed for healthy testosterone levels. For example, intense training without adequate rest and recovery can cause a significant reduction in testosterone levels and overtraining syndrome.

You may be at risk of overtraining syndrome if your are experiencing symptoms such as fatigue, low motivation, depression and a slow heart rate.

Testosterone has vital roles in muscle mass and strength as well as being vital for maintaining bone density. So, low testosterone can increase the risk of fractures which will negatively impact your training.

Because of the hormone’s role in muscle mass, if testosterone levels are too low, your body may start to break your muscles down to extract energy. Ultimately, this will affect your overall performance.

Frequently asked questions

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

  • What is testosterone?

    Testosterone is an important hormone in women and is responsible for regulating their sex drive too as well as regulating bone and breast health amongst other things.

    Testosterone levels are controlled by the brain and pituitary gland and once it has been made, it is transported by the blood to the various parts of the body which require it to function.

  • What are the signs of high testosterone?

    Some men are genetically predisposed to increased testosterone. An increased testosterone count in men can be caused by adrenal or testicular tumours. Even harmless tumours, known as benign, can increase testosterone levels. Signs of high testosterone in men include:

    • Aggressive or irritable behaviour
    • Acne
    • Oily skin
    • Sleep apnoea
    • low sperm count

    Taking too much testosterone replacement therapy can also result in a high level and may be accompanied by some of the unpleasant side effects. Increased testosterone also raises cholesterol levels which can put  men at greater risk of  heart attacks and stroke.

  • What is polycystic ovary syndrome (PCOS) in women?

    PCOS affects the function of the ovaries in women. It is a common condition where there is an increased production of follicles and testosterone. Within these follicles, eggs develop but are not released. That means ovulation doesn’t occur and can make it difficult to conceive.

    Approximately one fifth of women in the UK have PCOS and almost half experience no symptoms.

  • What is testosterone free and total testosterone?

    Two types of testosterone can be tested, free and total.

    Most testosterone molecules bind with sex hormone-binding globulin (SHBG) or albumin. This is known as bound testosterone.

    Free testosterone, however, isn’t attached to any other molecules in the blood and so is readily available for use by the body. Total testosterone measures the combined amount of free and bound testosterone. So, your total testosterone level will always be greater than your free level.

  • What is the normal testosterone level for men?

    The normal testosterone level for men is between 8.65 nmol/L and 29 nmol/L.

  • Does testosterone increase when you work out?

    Exercise initially increases testosterone levels when you workout but the effects may not be long-term.

    There are specific types of exercise which can help to support the production of testosterone, particularly strength and resistance-based exercises.

  • Do I need to take a testosterone supplement if my level is low?

    TRT should only on the advice and guidance of a medical doctor. For those competing in sport, testosterone is on WADA banned list.

  • How can I get my testosterone level up?

    Taking part in strength and resistant type exercise can help with the production of testosterone. Other factors which can support testosterone levels are getting good quality sleep, eating a healthy balanced diet, losing weight if you’re overweight and reducing stress.

  • How do I know if I have PCOS?

    You will need a diagnosis from a registered medical professional, but a high testosterone level can be an indicator of PCOS. You may also experience symptoms like excessive hair growth, irregular periods, weight gain and difficulty conceiving. The condition also increases the risk of type 2 diabetes.
