Some Frequently Asked Questions are stated below:

What do we measure?

We measure the number of progressive motile sperm cells (the only cells that can fertilize a woman)

How to interpret the result color?

The darker the better, as shown on the reference color (indicated with the inserted ”sperm cells”)

  • The result is NOT a YES or NO answer.
  • Remember it only takes one sperm cell to fertilize the egg.
  • To have a normal sperm quality you have to have a minimum of 5 million progressive motile cells/ml.
  • The result shows how many progressive motile cells there are in the sample.
  • The color of the result should be compared to the reference color that is closest to what is shown in the result window.


Understanding the Result depends on the light condition.  The result will or may appear blue/purple like below:

How does the SwimCount™ Test work?

There are three chambers in the device. Only Progressive Motile Sperm Cells (PMSCs) can swim from chamber no. 1 (Sample Chamber) into chamber no. 2 (Separation Chamber). The PMSCs get stained with a dye in chamber no. 2, which produces the color in chamber no. 3 (Detection and Result Window). The more PMSCs in the semen sample, the darker the color in the Detection and Result Window. A PMSC is the only sperm cell that can fertilize an egg.

How do I read the result?

Please download this guide on how to read the results: Guide to Readouts.


Are there any factors that I should be aware of that can destroy the test result?

Yes, the following can destroy the result:

  • Taking the test too soon after your last ejaculation (should be at least 2 days after, but not more than 5 days).
  • If there is not exactly 0,5 ml. of the semen sample collected in the syringe.
  • Not keeping the device steady on a horizontal surface throughout the test.
  • If there are bubbles in the sperm when put into the device.
  • If the device is shaken.


How long time will the result be staying in the device?

  • The test result must be read within 5 minutes after pulling back the slider. The result might be biased if left for too long. It is recommended to take a picture for documentation within 5 minutes. After 5 minutes, the test result will not be valid.


Is there anything I can do to improve my progressive motile sperm count?

The following may help to improve your sperm quality:

  • Stop taking anabolic steroids. Male fertility often returns to normal once use of steroids is discontinued. But do not stop taking any prescribed medication without consulting your doctor.
  • Take showers instead of hot baths. Long, hot baths may impact your sperm quality.
  • It is always worth taking care of yourself and factors like eating healthy, exercising regularly, quit smoking and reducing alcohol consumption will improve your health.


How accurate is SwimCount™?

  • SwimCount™ has an accuracy of 96%.
  • SwimCount™ has a sensitivity of 98% and specificity of 95%. 
    This means that if the test shows that your semen sample has less than 5 million Progressive Motile Sperm Cells, it is 98% likely that the test result is correct. If the test shows that your semen sample has more than 5 million Progressive Motile Sperm Cells per ml., it is 95% likely that the result is correct.


Why is SwimCount™ better than the other test kits already available on the market?

  • SwimCount™ is the only home test that is able to measure the concentration of Progressive Motile Sperm Cells which are the only sperm cells that can fertilize an egg and therby make a woman pregnant. SwimCount™ does not just measure your total count of sperm cells in your ejaculate but is able to seperate the "good and useable/progressive" sperm cells from the rest and thereby is able to give you a valid answer to your fertility potential.


Has SwimCount™ been approved by the authorities?

Yes, SwimCount™ is approved by the following authorities.
  • SwimCount™ has as of May 29th 2015 been granted the CE certificate for sales in the entire European Union. The certificate is issued by The British Standards Institution
  • SwimCount™ has as of June 27th 2019 received an FDA 510(k) Clearance for sales in the U.S.
