- Sperm Motility grading.

Sperm Motility grading.

(Human sperm stained for semen quality testing in the clinical laboratory.)

• Grade 1: sperm are immotile meaning that they fail to move at all.
• Grade 2: sperm are labeled as non-progressive motility because they do not move forward despite the fact that they move their tails.
• Grade 3: sperm (non-linear motility) also move forward but tend to travel in a curved or crooked motion.
• Grade 4: sperm are known to have progressive motility meaning they are the strongest and swim fast in a straight line.

Ideal sperm quality dictates that a man should have grade 3 or 4 sperm in order to fertilize an egg.
