Fertility tests for men can give valuable insights into sperm health, which are male reproductive cells [1]. There are many different kinds of fertility tests, each measuring different aspects of male fertility health.

The YO male fertility test is a type of test that can be performed at home and helps you assess your sperm health. Being an at-home test option, it bypasses many barriers that a man has to go through for fertility testing, including hesitation and privacy concerns.

But what does this test measure? How are YO sperm test review? More importantly, how accurate are YO sperm test results?

Let's explore the answers to all these questions in this article.

What is the YO Male Fertility Test?

The YO male fertility test is a procedure that uses a smartphone to analyze two important sperm parameters which are sperm count and sperm concentration [2]. It is an FDA-approved test, meaning it can show accurate results in most cases.

The YO test measures how well the sperm cells can swim, or in other words, sperm motility. The test provides a "YO Score," which shows sperm health when you compare the score with the standard score mentioned in the guide [3]. The YO fertility test uses WHO (World Health Organization) guidelines to offer accurate results for fertility health.

How to Know If Your Sperm Are Fertile?

You can determine sperm health or how likely a sperm can fertilize the female egg based on the following factors:

• Sperm Count: It is a measure of how many sperm cells are present in the ejaculate fluid. Experts consider that above 15 million sperm per milliliter of semen is a normal sperm count [4].
• Sperm Motility: Sperm motility means how well your sperm cells can swim [5]. It is an important factor in male fertility as sperm cells are required to swim inside the female reproductive tract to fertilize an egg.
• Sperm Morphology: Sperm morphology means the study of the size and shape of sperm cells. The size and shape of sperm are essential for fertility status, as any irregular sperm shape lowers the chances of fertilization [6].

How Does the YO Fertility Test Work?

The YO fertility test is a simple test that can be performed at home. Here is a step-by-step procedure on how to perform the YO fertility test:

1. The first step is to connect the YO test device to a smartphone or computer via secure Wi-Fi.
2. Download the YO app, power the device, and collect the sperm sample in the collection cup provided.
3. Mix the liquefaction powder provided with the test kit into the sperm sample, then draw some of the sample with a pipette and place a drop onto the slide's red dot section.
4. After inserting the slide into the YO device, the test begins, which can take around two minutes.
5. You will get results on your smartphone or computer in the form of a YO score and a live video of sperm activity. This score indicates the number of motile sperm present in the sample. You can also watch the video to witness the sperm movement. By carefully following the sperm check test instructions, you can ensure accurate results about your sperm health.

The YO test score ranges from 10 to 90 in steps of 10. A score of 20 indicates your fertility health or sperm health is above 20% of men who have fathered children. Similarly, a score of 90 places you above 90% of men with children in terms of sperm motility.

At-Home Sperm Test Accuracy

We all accept the fact that home fertility tests are convenient and often less expensive. But most of us also feel skeptical about their accuracy and ask questions like, How accurate are at-home sperm tests like the YO Male Fertility Test?

The YO male fertility test is an FDA-approved test, which makes it among the best at home sperm test. This test analyzes your motile sperm concentration following WHO guidelines.

All you need to do is read the YO sperm test instructions carefully and perform the test according to the instructions. If you are trying to conceive, it is not a good idea to just rely on home fertility tests, and you must share your concerns with a fertility expert.

Limitations and When to Consult a Specialist

The YO fertility test can be considered the first step towards improving fertility, but it is not perfect, just like any other home fertility test. For example, it does not measure sperm size and shape — morphology — which is a vital aspect of sperm health and determines the chances of conception.

This is why a fertility expert may recommend a full fertility test if you are failing to conceive. A full fertility analysis can provide more details, like information about hormone levels and sperm morphology, which gives a complete picture of reproductive health. In addition to testing, some men opt for fertility supplements that support sperm health and overall reproductive function.

Conclusion

The YO male fertility test belongs to the category of at-home fertility tests and is considered among the best home sperm count test. Since at-home fertility tests provide you comfort and peace of mind about your privacy, they are quite popular.

The YO fertility test tells about how many motile sperm cells your ejaculate fluid contains. Based on this, you will get a score that represents your sperm health. Although it is FDA-approved and follows WHO standards, it is still not a replacement for a full fertility test in a fertility clinic, such as semen analysis.
