Fertilization of an egg ordinarily requires a living, motile sperm that can swim into the fallopian tube where the sperm binds to the egg and penetrates the outer membranes. The stronger the sperm, the faster it swims.
Motility is an estimate of the percentage of motile sperm and is a measure of fertility potential of the donor’s sperm.
