Some Frequently Asked Questions are stated 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.

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 95%.
  • SwimCount™ has a sensitivity of 96% and specificity of 91%. 
    This means that if the test shows that your semen sample has less than 5 million Progressive Motile Sperm Cells, it is 96% 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 91% 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
