Moreover, (i) the activities of antioxidant enzymes within the seminal plasma and spermatozoa from older men may be reduced and so spermatozoa may be more vulnerable to mutational changes than spermatozoa from younger men; and (ii) late spermatids, and immature and mature spermatozoa do not have a DNA repair system.
