Home sperm examination? YO is the answer!

YO Home fertility test is an automatic examination of spermiogram showing sperm content in 1 ml sample. YO is the only one in its category which includes only movable and functional sperms into a result and compares it with World Health Organization (WHO) recommendation.


It will determine the concentration of moving sperm and “YO score” that will evaluate your fertility potential. The results can be used as a basis for consultation with your doctor, because YO can guarantee 97% accuracy of the test result.

The package contains complete accessories for 2 spermiograms and YO device for sample examination, which can be used repeatedly. An interactive application will guide you through the whole process, shortening the result with a funny quiz. Find out how you are doing and take steps to improve!

The decision was made. We will be family! But...

What if the results are not good?

Sperms are very sensitive to your lifestyle, so you can effectively change their quantity and quality by changing your regime. And it really makes sense, because 40% of the inability of a couple to spawn a child is on the man's side. Based on your current “YO score”, the app will suggest you possible solutions and procedures.

It is better to examine your sperms with 2 or more tests, 1-2 weeks apart. So you can easily see changes of your YO score and impact of your effort on the ability to father a child. However, the WHO fertility limit starts at 6 million sperm in 1 ml and more than 15 million / ml with more than 4% of normal sperms is considered “normal”.

Even the tough guys can worry

Is spermiogram really reliable?

Everything is carefully tested in advance - use, safety and reliability. The YO test has received CE certification and reliability has been tested in extensive tests that have passed over 300 FDA test participants.

YO is developed by MES company, which is the largest provider of automatic sperm analyzators for professional departments in US. MES has more than 20 years of experience in automatic sperm testing.
