What is MOT when talking about sperm quality?
You have probably come across the term MOT if you have visited Cryos’ donor search. But what does MOT mean when talking about donor sperm? And which considerations should you make before deciding on what MOT to choose when you are going to order donor sperm for fertility treatment?
What does MOT mean?
There are different ways to measure sperm quality. One of the parameters is MOT which is short for motility. Motility, in this context, is the number of sperm cells per millilitre semen that are able to swim. For example, if you have a sperm sample categorized as MOT10, there will be a minimum of 10 million alive sperm cells per millilitre semen after freezing and thawing the sperm straw. A MOT30+ contains more than 30 million sperm cells per millilitre semen.
A sperm straw contains 0.5 millilitre sperm and therefore, there are 15 million or more sperm cells in one MOT30+ straw.
Which MOT to choose for your fertility treatment?
When ordering sperm at Cryos, you can choose from MOT5 up to MOT30+. The reason for us to offer sperm samples with different MOT is for you to choose exactly what is needed for your treatment. You do not need to pay for more than what you need.
We recommend different MOT for different treatments. If you need donor sperm for treatment with IUI, we recommend that you use one MOT10 IUI-ready straw per treatment cycle. You can also use sperm straws with a higher or lower MOT.
We always recommend you to talk to your fertility clinic about what MOT to choose for your treatment.
What is good sperm quality?
Sperm quality is not only measured by the number of alive sperm cells in a sample. There are several other ways to look at sperm quality. For example how well the sperm cells move as well as their size and shape. Moreover, laboratory technicians can observe how sperm cells interact with their environment. Some men produce sperm cells that do not respond well to freezing and thawing and therefore, the sperm may not be well suited for donation or freezing for later use.
Sperm quality can vary
Sperm quality varies from man to man, but it can certainly also vary over time for individuals. Therefore, if you find your dream donor when browsing our donor search, and he only has MOT5 straws in stock, don’t worry. He will most likely be able to deliver sperm samples with a higher MOT another time.
