We have chosen the Danish brand SwimCount because it is among the most accurate sperm tests on the market and because it – unlike several other tests on the market – gives a more complete picture of the man's sperm quality. SwinCount not only measures the number of sperm, but the number of sperm that can swim and move, which is a prerequisite for the sperm to reach the egg in the woman's fallopian tube. A high number of sperm cells that do not move will therefore still appear as low sperm quality with Swimcount, where other tests will say that the sperm quality is high because there are many sperm cells. We love precision and correct answers, which is why we have chosen to sell SwimCount. Buy them here.
