Artificial insemination is made useful by the possibility t o store semen in liquid or deep-frozen conditions. This storage causes damage to spermatozoa, the indications of which are lowered fertility and -higher embryonic mortality. The effect of sperm storage on DNA changes and conscquently also on chromosomal aberrations is unknown. Egg cell aging in rabbits prior t o fertilization causes chromosomal abnormalities (SIIA\’ER and CmK 1967); therefore it is o f importance to know the possible influence o f the sperm aging effect. Spermatozoa aged during storage fertilize a significantly smaller proportion o f eggs than fresh spermatozoa; and the fertilization appears not to be a random process (Koctrc et a]. 1970). SMITI-I et al. (1969) demonstrated the fertility with damaged spermatozoa. The interactive role o f sperm age 011 fertility and embryonic mortalitv in rabbits has been demonstrated (S.rRANzmC;l
