YO HOME SPERM TEST REVIEW

Introduction

Yo is a clever device which allows you to test your sperm at home.  With the help of your mobile phone, you can actually see your sperm cells swimming and understand more about the health of your sperm.

How Does Yo Work?

The Yo kit contains everything you need to test your sperm. The kit includes the Yo device and charging cable, collection cups, testing slides, plastic pipettes and liquefying powder vials.

It sounds like a lot of equipment but don’t worry- you will be guided through the whole process by the helpful Yo app. The first thing you will need to do is download the Yo app which is available for free on the App store and Google Play.

You will then need to collect your sample in a collection cup. Yo advises that you abstain from ejaculation for 2 to 7 days to get accurate results and also avoid using lubricants as this can affect the readings.

The next step is to add one vial of the liquefying powder to the collection cup. This powder alters the consistency of your semen sample to make it suitable for testing and you will need to mix the sample using gentle rotations for approximately 10- 15 seconds. The powder will turn your sample a strange pink colour- don’t panic, this is all part of the process!

You will need to let your sperm cells rest for ten minutes, which you can time using the app. While you are waiting, the Yo app guides you through a short sperm trivia challenge to pass the time. The quiz also provides you with lifestyle advice and tips on how to improve your sperm quality.

Mix the sample again and using the pipette provided, you will need to collect a small amount of your sample. Place one drop of your sample onto the red dot on the Yo slide provided in the kit. The slide will fill automatically when you have done this.

Next, be careful not to touch your sample as you insert the slide fully into the Yo device, facing upwards. The Yo device acts as a microscope and it records a video of your sperm cells in action. This can take a couple of minutes. Yo will then analyse your sperm and provide you with your results.

What Does Yo Reveal About Your Sperm?

Motile Sperm Concentration

Yo measures your motile sperm concentration. This shows how many sperm cells are moving correctly and this is an important marker of fertility.

Sperm concentration alone only tells you how many sperm cells are present but for fertilisation to occur, the sperm cells need to be able to swim towards the egg to successfully conceive.  Yo’s use of the motile sperm concentration is an excellent feature which sets it apart from many other cheaper home sperm tests.

Yo measures whether your motile sperm concentration is above or below six million motile sperm. This is based on the World Health Organisation’s reference values. If you have a low result, Yo recommends retesting your sperm after 1-2 weeks.

Yo Score

Yo goes one step further than other home sperm tests by comparing your motile sperm concentration to other men who have had children. This is shown in your Yo score, which ranges from 10 to 90 in intervals of 10.  For example if your Yo score is 30, your results rank above 30% of fathers.

The higher your Yo score is, the higher your chances are of conceiving more quickly. Your Yo score is particularly useful as a simple indicator of your fertility which you can compare over time.

Sperm Video

This is probably the coolest part of using Yo. Yo will provide you with a video of your sperm cells in action. You can share this with your fertility doctor or just keep it for personal viewing.

How Accurate Is Yo?

Yo is over 97% accurate. This impressive accuracy is backed by scientific evidence in the form of a study conducted on 144 samples from 24 men 1.  Yo is also FDA and CE certified.

Is My Privacy Protected?

Yes. Your results and video are only stored in the Yo archive on your device and these are not shared via your internet connection unless you choose to do so.

How Much Does Yo Cost?

The Yo home sperm test kit costs £145.99 and it is available here. This includes all of the equipment required for two tests.

The Yo test device itself is reusable but the other equipment such as containers and pipettes are not. Therefore refill kits are also available for £47.50 which contain everything you need to carry out two more tests.

This is a useful option if you want to track changes in your sperm health over time. The Yo app is also built with long-term monitoring in mind as you can view all of your previous results in the app’s results archive.

Verdict

Yo is a clever device which analyses your motile sperm concentration. This is a key marker of sperm health and your chances of conceiving, and this is more information than you would get from many other cheaper home sperm tests.

Yo is expensive but it is reusable with the help of refill kits. The high accuracy of Yo and the way in which it can be used to analyse changes in your sperm health over time justifies its price tag.

This is particularly true when balanced with the costs of conducting sperm tests in fertility clinics which cost as much as £150 to £200 although these are more comprehensive than Yo. Tests in a fertility clinic also involve a great deal more stress than using Yo in the comfort of your home.

OUR RECOMMENDATION

Use Yo if you have been trying to conceive naturally for six months. This is when it would be useful to check that your sperm cells are as healthy as possible to maximise your chances of having a baby.

Boost your chances of scoring highly with Yo by improving your health and lifestyle as soon as possible. This includes exercising regularly and eating a healthy diet rich in fruit and vegetables.
