What is MOT?

What is MOT when talking about sperm quality?

Browsing through Cryos’ donor search, you have probably come across the term MOT. But what is MOT when talking about sperm quality, and which considerations should you make before deciding on what MOT to choose when ordering donor sperm?

MOT stands for motility

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 amount of sperm cells per millilitre 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 after freezing and thawing the sperm straw. A MOT50+ contains more than 50 million sperm cells per millilitre semen.

A sperm straw contains 0.5 millilitre sperm, and therefore you will have 25 million or more sperm cells in one MOT50+ straw.

Which MOT to choose for your treatment?

When ordering sperm at Cryos, you can choose from MOT5 up to MOT50+. 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.

At Cryos we recommend different MOT for different treatments. For example, if you are going to have treatment with IUI, we recommend that you use one MOT10 IUI-ready straw per treatment. You can also use straws with a higher or lower MOT.

If you are going through IVF or ICSI treatment, we recommend you to use one MOT5 straw (IUI-ready or ICI). However, a straw with a higher MOT can also be used.

We always recommend you to talk to your fertility clinic about what to choose for your exact treatment.

What is good sperm quality?

Sperm quality is not only measured by the amount of alive sperm cells in a sample. There are several other ways to look at sperm quality. This could be how well they move, their size and their shape. Moreover, laboratory technicians can observe how the 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. You can listen to professor Allan Pacey speak more about sperm quality here.

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 density of sperm cells another time.
