FAQ

What is a sperm analysis, and what does it tell you?

Sperm analysis should test: 

• Volume of semen 

• Quantity of sperm (concentration and total number of spermatozoa) 

• Motility: how efficiently and how fast sperm move 

A good sperm analysis is not a direct test of fertility, it provides guidance to the chance of having a baby and can be a starting point for further investigation; achieving a pregnancy remains possible even for those with severe deficits.

If the Mojo at-home sperm test detects abnormalities, our fertility experts will assist you in pinpointing the underlying problem and provide personalised advice to help improve your sperm quality.

What is the prevalence of sperm analysis in the fertility equation?

When a couple has trouble conceiving, 50% of the time, it has something to do with sperm. People with sperm have a more prominent role than just cum.

When is it vital to get a sperm test?

You are thinking about starting or expanding your family 

Couples who have an immediate pregnancy plan should ensure they know their reproductive health status before trying to have a baby. If you are in this category, it is highly recommended to take a Mojo at-home sperm test for your peace of mind.

Actively trying to conceive naturally

If you have been trying to conceive for 6-12 months, but pregnancy is not happening, it is essential to get tested. In some specific cases, you will need to request a sperm analysis, for instance, if you: 

• went through a cancer treatment 

• are experiencing prolonged stress and anxiety 

• have a chronic condition like hypertension or diabetes 

• face sexual performance issues such as erection or ejaculation difficulties 

• have an infection of the scrotum or prostate  

• have taken a long-term prescribed medication, or you participate in recreational drug use 

• have had surgery for non-migrated / undescended testicles  

Sperm health examination is a quick and straightforward process, another reason to get tested proactively and regularly. You can order your test today here.

Does Mojo’s results report indicate if I am fertile or infertile?

No. Mojo provides results on your overall sperm health quality displayed as Above or Below the WHO thresholds, along with accurate detailed analysis of your sperm count, motility, semen volume, and the number of total sperm. The higher the numbers, the higher the chances of conceiving naturally. However, if the numbers are lower than the WHO thresholds, it does not necessarily mean you cannot conceive.

Sperm health is a non-static diagnosis, and it can be heavily influenced by our lifestyle, what we eat, and our state of mental health. With the Mojo at-home sperm test kit, you can test your sperm in 48h and get access to our fertility specialists for personalised and expert advice to improve your fertility, increasing the odds of conceiving naturally.

How long before a sperm test can/should I ejaculate?

Studies have shown that repeat and frequent ejaculation leads to the release of competent sperm that have not been stored in the testes for long enough.

To ensure the sperm analysis results can be assessed against existing data and reports relating to sperm function or pregnancy, the sperm sample should be collected after a minimum of 2 days and a maximum of 7 days of sexual abstinence. This ensures that advice can be given on chances of pregnancy, further testing/investigation, or type of assisted conception if that is needed.

If repeat analyses are required, the number of days since the last ejaculation should be as constant as possible at each visit.

How much does male fertility testing cost?

At a traditional lab or clinic, the cost of a sperm analysis is typically around 200–400 sterling pounds. That is not to mention the sterile user experience spanning the waiting room and generating your sample on-site.

Mojo's at-home sperm testing cost is a fraction of a traditional clinic. A sperm analysis costs 150 sterling pounds and can be combined with a free and online access to fertility specialists to hep improve your results.

Do I need a prescription for a Mojo at-home sperm analysis test kit?

You do not need a doctor's prescription to order a Mojo kit. Going the traditional route, sperm health fertility isn't prescribed until a couple has been trying for at least 12 months. It should though! Human sperm health issues can be fixed with simple lifestyle changes, especially if detected early on.

Is the quality of sperm static?

No. It takes around 90 days for sperm to be produced, which means that what happened 90 days ago affects your sperm now. We know that our lifestyles like smoking, eating, drinking, drugs, and how much we exercise affect sperm quality and quantity.

Can men take their fertility for granted?

No. According to a study from 2017, male fertility (measured in sperm concentration) halved, decreasing by 50% between 1973 and 2011. The down-trend is not stopping anytime — our sperm count and testosterone levels decline by 1% every year. This baffles the scientific community – there isn't enough research to explain this exponential drop. One thing scientists do agree on is that our lifestyles can directly affect fertility. What we eat, where we live, what we smoke, the drugs we take, how much plastic we use, how much we exercise – all these factors can harm fertility.

When does it make sense to perform a sperm test?

Sperm quality is influenced by our lifestyle, general and mental health, and environment, and life is not constant. We advise humans with sperm to proactively test their sperm health to ensure their fertility is under control, even if they're not trying to conceive.

That being said, if you are experiencing any of the medical conditions below, you have higher odds of facing poor sperm health:

• Hypertension and diabetes can degrade the ability of the body to produce sperm and lower testosterone levels. 

• Obesity can degrade our fertility in various ways, including directly causing hormone imbalance that reduces sperm count. 

• An imbalance or decline of hormones such as FSH, LH, and testosterone  

• Problems with sexual function such as low sex drive, premature ejaculation, or difficulty maintaining an erection  

• Steroids stimulating muscle strength can cause the testicles to shrink and sperm production to decrease.  

• A failure in testicles to produce sperm, either due to medical conditions such as a varicocele, after surgical procedures, or cancer treatment.  

• A blockage or absence in the transport system that delivers sperm from the testicles to the storage area or out of the body during ejaculation  

Because sperm take about 90 days to be produced, it could take at least 3 months for any lifestyle changes you make to impact your sperm health. Sperm testing in advance can help ensure that, by the time you're ready to start a family, your sperm is in its best possible shape.

How accurate is at-home fertility testing?

Mojo's at-home sperm testing kit uses a proprietary transport package developed with our scientific partners. Our package, including our clinically-validated transport solution, preserves the quality of the sample for more than 24h. With sperm shipment, you may experience up to an 8% drop in sperm motility, a tiny error margin with nearly no effect on test efficacy.

What enables Mojo to offer clinical-grade sperm tests is that we operate our own labs and use our purpose-built AI-powered sperm analysis platform. Our AI performs at 97% accuracy with less than a 20% error margin — validated against WHO standards & ISO 15189 compliant labs such as the Karolinska Institute in Sweden.

What's the difference between an over-the-counter sperm count test and a complete sperm analysis?

Appropriate sperm testing should be only done by a specialized laboratory that uses methods recommended by the World Health Organisation (WHO), providing key sperm parameters: 

• Volume of semen 

• Quantity of sperm (concentration and total number of spermatozoa) 

• Motility: how efficiently and how fast sperm move 

Over-the-counter sperm tests or DIY phone-accessory-tests only provide results with questionable accuracy on the sperm count or the number of motile sperm, which is incomplete information on your sperm health. If you are trying to conceive or are facing conditions that could lead to a low sperm count or keen to understand the status of your sperm health, we recommend performing the test in a fertility clinic or ordering Mojo's sperm testing kit.

You can contact us to speak with our fertility specialists to learn which fertility test suits you most.

I'm considering hormone or gender reassignment. Is the Mojo at-home sperm kit right for me?

People should consider a sperm analysis before gender reassignment surgery even if they have been on hormone treatment for a while, as they may still have healthy/viable sperm. Since continued hormone exposure can cause sperm production to decline, we suggest speaking with our fertility expert about sperm freezing plans.

Can I use lubricant when masturbating in the cup?

No, you should avoid the use of lubricants. If you must, use a lubricant made specifically for fertility purposes, as these specifically forgo adding spermicidal chemicals.

I only ejaculated a small amount. Will my sample still be viable?

It is not a problem, and any amount can still be analysed.
