It's three main numbers and a couple of supporting ones. Here's what each one checks, and where its usefulness ends.
Most people open a semen analysis looking for a grade. The test doesn't give one. It compares your numbers to men who got a partner pregnant within a year of trying, and the "normal" cutoff sits at the bottom 5% of that group. Clearing it means a sample isn't in the lowest slice of recently fertile men.
