Further testing for ED

Testosterone Venous Blood Test

Since you have experienced ED symptoms, it’s important to assess your testosterone levels promptly to detect any potential health risks. Research shows that men with erectile dysfunction are 59% more likely to have heart disease and 34% more likely to have a stroke*. Therefore, it’s crucial to identify any potential risks early and initiate proper treatment if required. Once you complete a comprehensive venous blood test, our doctors will review your results with you, helping you assess your risks and providing guidance on effective management.

1 in 3 men with ED have low testosterone levels*

Testosterone deficiency can lead to symptoms such as loss of muscle mass, increased body fat, mood swings, and poor sleep, along with erectile dysfunction. It can also result in serious health risks, including osteoporosis, cardiovascular disease, and an increased risk of mortality. Therefore, it's crucial to get an accurate diagnosis, especially if you’re experiencing one or more symptoms of low testosterone.

SYMPTOMS

The signs of low testosterone

If you experience erection problems along with any of these symptoms, further testing is advised to rule out more serious health issues.

Erectile dysfunction

Low-T reduces nitric oxide synthesis, which is essential for the vessels carrying blood to the penis.

Decreased libido

Low-T reduces the hormonal stimulation necessary for sexual desire and arousal.

Fatigue

Low-T reduces production of red blood cells, which impairs oxygen delivery to tissues and decreases overall energy levels.

Poor sleep

Low-T reduces the production of melatonin, a hormone essential for promoting restful sleep.

Mood changes

Low-T alters the levels of serotonin and dopamine, key neurotransmitters involved in regulating emotions.

Difficulty concentrating

Low-T impacts neural circuits involved in attention and executive function, thus diminishing cognitive performance.

Loss of muscle mass

Low-T reduces protein synthesis and increases protein breakdown in muscle tissue.

Increased body fat

Low-T slows metabolism, increasing fat storage in the body.

Reduced facial and body hair growth

Low-T shortens the time hair spends growing, resulting in thinner hair.

Paul

REAL PATIENTS. REAL IMPACT.

Paul, 54

Key symptoms: I was experiencing certain symptoms for around 12 months such as loss of concentration, tiredness all the time, and low libido.

Motivation to treat: So my wife said to me one day, are we ever going to have sex again?

Testosterone improvement: My most recent blood test with Numan was 13. I think my first ever one back in October was 8. So massive, massive transformation.

Symptom improvement: I began to feel the benefits of the treatment after about 4 or 5 months. It was just like a light switch. I had more energy, I was more focused, and just had a general sense of wellbeing.

health profile

Which health areas are assessed?

We get a complete picture of your health to make sure we provide the most suitable treatment for you.

Hormone levels

Analysing testosterone and oestrogen levels, thyroid function, reproductive health, and pituitary function to identify imbalances.

Anaemia

Testing for anaemia helps ensure an accurate testosterone deficiency diagnosis and enables a comprehensive treatment plan for better overall health.

Heart health

Prior to starting treatment, it's important to assess cardiovascular risk, by identifying this we can manage risk factors along the way.

Kidney & liver function

Pre-existing issues can affect how the body processes testosterone treatments.

Diabetes

Ensuring stable blood glucose levels before starting treatment reduces the risk of exacerbating diabetes-related complications.

Prostate health

Assessing prostate health before initiating testosterone treatment reduces the risk of exacerbating any existing prostate conditions.

Classifications of low testosterone
Low testosterone (clinically known as hypogonadism) can be classified based on its origin and cause. There are two common classifications.
Primary hypogonadism

Origin: Also known as primary testicular failure, primary hypogonadism arises directly from problems within the testicles.

Common causes: The causes of primary hypogonadism can be diverse, ranging from genetic disorders like Klinefelter's Syndrome to physical issues such as undescended testicles, testicular injury, or the effects of cancer treatment. Ageing can also play a significant role in its development.

In these cases, the testicles themselves are impaired and fail to produce sufficient levels of testosterone.

What is considered a normal level of testosterone
What is considered a normal level of testosterone?

Even before birth, your testes start producing small amounts of testosterone. Levels increase throughout childhood and peak significantly during adolescence. By your early 20s, testosterone levels reach their highest point.

  • For adult men, a normal testosterone level ranges from 12 to 29 nmol/L.

  • These values do not account for age-related decline or individual symptoms, which your doctor will consider when interpreting your levels.

  • If your testosterone levels are less than 12 nmol/L and you have symptoms, you may benefit from testosterone replacement therapy (TRT) or alternative testosterone-boosting medications.

  • A 2022 study examined testosterone levels in 1,486 men aged 20 to 44. They determined normal testosterone levels for each age bracket by using the middle third of the data.

Who’s at risk?

As well as age, testosterone deficiency (TD) is also more common among men with obesity, type 2 diabetes, or cardiovascular disease. Even without these conditions, it can affect men from a surprisingly young age.

If you have TD, you may be showing symptoms such as fatigue, low libido, loss of muscle mass, and depression. Although these symptoms alone don’t mean you have it, experiencing even one of them could point to something deeper.

Significant contributors to low testosterone

Age

Testosterone levels decline as men age, typically by 1% per year after the age of 30, primarily as a result of gradual reduction in testicular function.

Obesity

Excess body fat boosts the enzyme aromatase, which turns testosterone into oestrogen. This lowers testosterone levels and disrupts overall hormone balance.

Sleep irregularity

Testosterone production follows the circadian rhythm. Disrupted sleep patterns can interfere with this natural cycle, leading to decreased testosterone production over time.

Diabetes

Type 2 diabetes is characterised by insulin resistance, which can disrupt hormone signalling pathways, including those involved in testosterone production.

Cardiovascular disease

Men with cardiovascular disease may suffer from low testosterone due to impaired blood flow to the testes.
