The difference between ICI and IUI Units - SellmerDiers
Your basket 0 items | 0,00

At SellmerDiers Saedbank we prepare the donor sperm so that it is specifically suited for the different types of fertility treatments.


We offer two different types of donor sperm: ICI units (unpurified sperm) and IUI units (purified sperm).


When you are doing research on a donor, you will be able to see how many ICI and IUI units we have in storage on that specific donor in the donor list. When you order donor sperm, you will have to decide on whether it has to be ICI or IUI.


Below, there is further explanation about the difference between ICI and IUI and which treatment each of them is best suited for.


ICI Units
ICI units are specifically prepared in our laboratorium for simple assisted insemination.


In the ICI units we retain all the natural tissues that are found in an ejaculation.


ICI is an acronym for the fertility treatment known as IntraCervical Insemination. With this treatment, a syringe is used to inseminate the donor sperm vaginally. ICI units may not be used to inseminate directly into the uterus (IntraUterine Insemination).


IUI units
IUI units are primarily prepared for treatments where the donor sperm is inseminated directly into the uterus. However, IUI units can also be used for self treatment in the same way as ICI units are used. In our laboratorium, we process the donor sperm so that the natural sperm tissue along with the dead, unusable sperm cells and other cells are removed, to which we add a preservative that makes it possible to freeze down the sperm but also provides the unit with the optimal pH.

  • IUI units are moreover well suited for IVF- and ICSI treatments. 
  • IUI is an acronym for IntraUterine Insemination which means insemination in the uterus. IUI, IVF and ICSI treatments may only be performed at a fertility clinic by a doctor or another experienced healthcare professional.  

What does MOT mean?
MOT indicates the amount of motile sperm cells, meaning forward-moving sperm cells. MOT is an acronym for Motile Total. MOT is often measured in millions per ml. (mio/ml).


Our laboratorium manufactures units with the amount of sperm cells that are optimal for the specific type of treatments performed using ICI and IUI units respectively. 


If you order ICI units, we guarantee 20 mio. forward-moving sperm cells and a min. of 1 ml. per unit. In our ICI units for self treatment you will receive double the amount of sperm cells for the same price when compared to units you can otherwise buy on the market.


Note that one unit is physically delivered in either 1, 2, 3 or 4 vials depending on the amount of motile sperm cells per vial.


Our IUI units contain 0,5 ml. and are found either as MOT10+ or MOT20+ per ml. They respectively contain a min. of 5 mio. moving, forward-swimming sperm cells and a min. of 10 mio. forward-swimming sperm cells. 


How many units should I order per treatment?

For simple assisted insemination:

  • For simple assisted insemination using ICI units you ought to order a minimum of 1 unit that will be MOT20+. We guarantee a minimum of 20 million sperm cells in all per unit, which will either be in 1 vial or divided in 2-4 vials.
  • For simple assisted insemination using IUI units you ought to order a minimum of 1 IUI MOT20+ per treatment. In order to reach a more appropriate volume for this treatment, you will receive at least two IUI units (tubes or vials), so that the combined amount will be at least 1 ml. The division of sperm cells in these units can vary.

For clinical treatment:

Before you order, we recommend that you ask your fertility clinic for advice about how many units you should order. Our recommendations for the specific treatments are as follows:

  • For IUI treatment you ought to order a minimum of 1 IUI unit MOT20+ or 2 IUI units MOT10+ per treatment.
  • For IVF and ICSI treatement you ought to order 1 IUI unit MOT10+ or possibly, 1 IUI unit MOT20+ per treatment.
