 "1 in 3 men with ED")
Low-T in 1/3 of ED cases in over 65s²
Testosterone deficiency reduces libido, impairs blood flow to the penis, and affects penile tissue health
 "90% go undiagnosed")
90% of men with low testosterone go untreated³
In fact, many men are misdiagnosed with having depression
 "Up to 2x more likely")
Up to 2x more likely if overweight or diabetic⁴
Men who are obese or have type 2 diabetes face a significantly higher risk of low testosterone
 "Up to 3x more likely")
Up to 4.4 times more likely to be depressed⁵
Low testosterone is strongly associated with an increased risk of depression
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.

FAQS
Got questions? We’ve got answers
A VBT is a blood test drawn from a vein, used to accurately measure testosterone levels in the bloodstream. It provides a detailed analysis of your hormonal health as well as other relevant biomarkers that help us to assess which treatment will be most appropriate for you.
Common symptoms include erectile dysfunction, fatigue, muscle weakness, depression, and difficulty concentrating. If you experience any of these symptoms, a VBT can help determine whether low testosterone is a contributing cause.
Hormone health blood tests help you to understand what impact your hormones might be having on your overall health and wellbeing. The tests can identify potential hormone abnormalities and give you a better understanding of why you might not be feeling your usual self.
Each blood test is easy to use, even if you’ve never used a home blood test kit before.
It only takes a small amount of preparation to successfully collect a blood sample and all the equipment you need to do so is included in the kit.
A summary of how to use the tests:
Wash your hands in warm water for 4 minutes and then dry them.
Use the lancet provided to prick your finger and collect a blood sample.
Post your sample to our accredited partner laboratory using the prepaid envelope included with your test.
Full instructions are provided with your test, which you should read thoroughly before use to ensure the best results.
To learn more about how to take a blood test at home, click here.
You should receive your blood test results three to five working days after you post your blood samples.
You’ll get an email notifying you that your results have arrived in your Numan account, so keep an eye on your inbox so you don’t miss them. Additionally, you’ll receive a written review of your results from one of our clinicians, which you can read alongside your results to help you understand them.
Once they’re in your account, you can view your results any time you wish. You can also view them in-app and save your results as a PDF to help you keep track of them (and show them to your GP if need be).
Yes. The hormone health blood tests are designed to be taken at home without professional supervision. Just follow the instructions in the kit and post your sample back to us using the prepaid envelope.
Click ‘learn more’ on each test to understand the key benefits and what biomarkers the kit tests for. From here, you’ll see the difference between each test and can select the one that most accurately aligns with your health status and goals.
Each test is a finger prick test, so you may feel a small scratch when you use the lancet provided with it to take a blood sample. This is only temporary, and any discomfort should subside swiftly afterwards.
The hormone health blood tests can only indicate rather than diagnose health issues. If you’re worried and suspect you might have an underlying health condition, we advise speaking to your regular doctor first. If you get any unexpected or unusual test results, this should also be flagged and discussed in more detail with your doctor.
