Screenshot of the electronic data input interface. The entry fields for sperm motility assessment are shown. A warning signal (in red) was shown on the second row of the last column when the sum of all motility grades was not equal to 100%. At least 400 spermatozoa were assessed in two replicates for motility assessment. The values between the two replicates were within the 5% error limit. Abbreviation: 50LPF – 50 low power field
