I found the Mojo experience seamless from start to finish, it's night and day when compared to an in clinic experience and cheaper too. I took this test to reassess existing issue I already knew I had, just to check where i'm at ahead of a potential second fertility journey.

A really convenient and much more comfortable way to check in on my sperm health. I felt more relaxed using this kit than going to a sperm clinic and was much happier with how I received my sperm results. Highly recommend as a way to manage and check in on your sperm health.

My friend and I were curious about our fertility, it's something every guy jokes about when they are younger but we thought let's actually get tested. Mojo was the no-brainer solution to doing it. I think this kind of basic health insight should be a standard practice for all men.

Mojo's at-home semen analysis is a test kit that evaluates up to 22 key biomarkers to assess sperm health and fertility potential. It is designed to be convenient, affordable, and accessible for men who want to monitor their sperm quality and take proactive steps to improve their chances of achieving a successful pregnancy.

The key parameters evaluated by Mojo's at-home semen analysis include semen volume, sperm concentration, sperm motility, total motile sperm count, and sperm morphology (available in our advanced sperm test). These parameters are all important indicators of sperm health and can provide valuable insights into a man's fertility potential.

Since the 1930s, fertility specialists have developed and standardized the sperm analysis test to assess sperm quality, which is crucial in determining fertility issues. The World Health Organization (WHO) has established standards for the test, including 22 biomarkers that measure key sperm markers such as semen volume, sperm concentration, total number, motility, and morphology. While the sperm analysis test is not a direct measure of fertility, it can provide valuable information on the likelihood of achieving a pregnancy and serves as a starting point for further investigations. Mojo's at-home sperm test includes all the key biomarkers and thresholds set by the WHO to evaluate sperm quality accurately. In case of any abnormalities detected by the test, our team of fertility experts can offer personalized advice to improve sperm quality and identify any underlying problems that may be impacting fertility.

Mojo's at-home sperm test uses a special transport media that protects and extends the life of your sperm during shipping. To return your sample to our lab, simply follow these steps:

  1. Package and return your kit: Use the packaging materials included in your kit to package your semen sample in the original shipping box. You can then schedule a return with Royal Mail for your sample to be shipped for free overnight or drop it off at a participating location.
  2. Analyze your sample: Once we receive your sample at our London hubs, our qualified fertility clinicians analyse it according to the WHO guidelines using a CE-certified and peer-reviewed AI-powered microscope. Our kit is designed to protect your sperm's quality for up to 48 hours, and we conduct a full test on arrival to ensure everything went smoothly in transportation.
  3. Get your results: Your results will be available on your online dashboard within 48 hours. If you choose the consultation option, you can schedule a video call with a fertility specialist to review your results and discuss how they relate to your fertility. All your information remains anonymised via your CLIENTID and lives on HIPAA-, GDPR-compliant servers.

We utilise a sperm preserving medium that has been shown to extend sperm function beyond 36 hours. Additionally, we employ thermally and mechanically protective packaging to ensure your sample is kept under optimal conditions during transport. We apply a correction to the measurement accordingly as every sample is unique and will respond to the process in it's own way. Other measurements like volume, concentration, and morphology are not affected by transportation.

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.

Mojo's at-home male fertility test is the only thorough male fertility test you can take from the comfort of your home to test your sperm health.

The Mojo male fertility sperm test is designed for people with sperm who want to understand their fertility and have peace of mind when trying to start their family.

This test is equivalent to taking a test with a fertility clinic - without leaving your home and awkward waiting rooms, sample cup in hand. It is an easy way to test, understand and - if needed - improve your sperm at an affordable price.

Thanks to Mojo's proprietary AI technology that has been developed in compliance with WHO standards and with the scientific team that co-developed these standards, you get 97% accurate results in 48h.

The test results are easy to understand and cover the essential parameters that are clinically and scientifically required to assess your ability to conceive.
