What can I learn from
a Male Fertility Test?

Our Male Fertility Test can help determine if your sperm health or hormone levels might affect your chances of conceiving. 

Infertility in men is usually caused by a problem with the sperm. So, our test offers clinical-grade semen analysis covering 22 key biomarkers, including sperm concentration and sperm motility (the percentage of sperm that are actively moving). 

Our fertility check also includes a Testosterone Blood Test. Testosterone is a key sex hormone, which plays several important roles such as helping to produce sperm and regulating sex drive (libido). A low testosterone level may result in decreased sperm production, which can affect your fertility.

How do Male
Fertility Tests work?

You'll receive two test kits in discreet packaging — your semen analysis test will be supplied by Mojo* and your testosterone check will be supplied by Medichecks. Both tests can be taken at home. 

Before taking your semen sample, arrange free collection from your home at a time to suit you (your sample must be collected no more than an hour after it’s taken). . Following lab analysis by Mojo’s AI-powered microscope, your result will be validated by an expert clinician. You’ll receive clear, easy-to-understand results via your secure online dashboard, alongside a detailed report. There’s also an optional consultation with a fertility expert to discuss your results in more detail. 

Your Testosterone Blood Test sample is returned separately, in the pre-paid envelope provided. Your results will be delivered direct to your MyMedichecks online dashboard, with a doctor’s comments and any next steps.

What key biomarkers does our
at-home semen analysis measure?

Our male sperm test covers all the biomarkers recommended by the World Health Organisation (WHO) for a thorough investigation of sperm health. 

It includes a complete analysis of 22 key biomarkers including sperm morphology (the shape and size of sperm, which is important for successful fertilisation of an egg), motility, concentration (the number of sperm in each millilitre of semen), semen volume, and total motile sperm count.

While over-the-counter male fertility tests typically only check your sperm count or the number of motile sperm, our home semen analysis offers the thoroughness of a fertility clinic test at an affordable price, with no appointments necessary.

of the test

Although semen analysis can give an indication of your fertility, it doesn’t test how well your sperm will interact with eggs. Therefore, a normal result can’t guarantee that you will have no problems conceiving.

Conversely, an abnormal result can’t diagnose infertility, but it may mean that you will find it more difficult to conceive and may require further investigations.

Testosterone Testosterone is a hormone that causes male characteristics. For men, it helps to regulate sex drive and has a role in controlling bone mass, fat distribution, muscle mass, strength and the production of red blood cells and sperm. Testosterone is produced in the testicles of men and, in much smaller amounts, in the ovaries of women. Testosterone levels in men naturally decline after the age of 30, although lower than normal levels can occur at any age and can cause low libido, erectile dysfunction, difficulty in gaining and maintaining muscle mass and lack of energy. Although women have much lower amounts of testosterone than men, it is important for much the same reasons, playing a role in libido, the distribution of muscle and fat and the formation of red blood cells. All laboratories will slightly differ in the reference ranges they apply because they are based on the population they are testing. The normal range is set so that 95% of men will fall into it. For greater consistency, we use the guidance from the British Society for Sexual Medicine (BSSM) which advises that low testosterone can be diagnosed when testosterone is consistently below the reference range, and that levels below 12 nmol/L could also be considered low, especially in men who also report symptoms of low testosterone or who have low levels of free testosterone.

How to prepare
for your test

Special Instructions

Prepare for your test by following these instructions. Take your sample before 10am. Avoid taking a finger-prick sample from a finger used to apply hormone gels/pessaries/patches in the past 4 weeks. Use gloves to apply these. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed. For information on the semen analysis test please see our FAQS below and

Can I take a Male Fertility Test at home?

Yes, you can take your Testosterone Blood Test and semen test at home. The two tests will be delivered separately.

Your semen analysis test kit will be supplied by Mojo. It includes everything you need, including easy-to-follow instructions on how to take your test and return your sample.

Your Testosterone Blood Test kit will be supplied by Medichecks. It includes clear instructions and a pre-paid return envelope for your blood sample.

Are home Male Fertility Tests accurate?

Mojo’s AI-powered semen analysis platform operates at 97% accuracy and is validated by an expert clinician against WHO standards. This means this male fertility check offers accuracy comparable to that of a test taken at a fertility clinic, but it can be taken in the comfort of your home.

How long before a sperm test should I ejaculate?
You should avoid ejaculation for a minimum of two days and a maximum of seven days prior to taking a sperm test. This allows your results to be assessed against existing data and reports relating to sperm function or pregnancy. And it helps you get the most accurate advice on your sperm health and fertility potential.
Is my semen sample safe in transit?
Yes, Mojo’s at-home sperm test uses a special transport media that protects and extends the life of your sperm sample during transit. You can also help ensure the safety of your sample by following the packaging and returns instructions carefully.
What is a low sperm count?
A low sperm count is defined as less than 15 million sperm per millilitre of semen. A low sperm count can make it more difficult to conceive naturally, although successful pregnancies can still happen.
Do I need to take my blood sample and semen sample on the same day?
Ideally, your testosterone blood test and semen analysis test should be taken as close together as possible. Although the two samples don’t have to be taken on the same day, it’s important that they’re taken within a couple of days of each other. This ensures that you’ll receive the most accurate picture of your fertility. In addition, your testosterone test should be taken before 10am.
