Progression –Progression refers to the forward movement of sperm and is recorded as: Grade 4: Fast and forward progression where sperm move in a straight direction. Grade b (slow progressive) sperm swim forward, but either in a curved or crooked line, or slowly (slow linear or non linear motility).
