<P> Back and forth movement of the tail results from a rhythmical longitudinal sliding motion between the anterior and posterior tubules that make up the axoneme . The energy for this process is supplied by ATP produced by mitochondria . The velocity of a sperm in fluid medium is usually 1 -- 4 mm / min . This allows the sperm to move towards an ovum in order to fertilize it . </P>
