Blood sera obtained from 2 064 bulls randomly selected in artificial insemination stations and bull rearing stations were examined for the presence of autoantibodies to the sperms (AbS) using the developed enzyme-linked immunosorbent assay (ELISA). At serum dilution 1 : 40 the incidence of positive bulls was 26.7%. In individual investigation periods the incidence of AbS ranged between 9 and 39.7%. In a set of 586 bulls the presence of antibodies to Chlamydia sp. was detected in blood sera in 32.1% by a micromethod of complement binding. The possibility of involving genital infection as one of several factors taking part at the development of AbS is discussed. Examination of blood sera of 981 boars for the presence of AbS by ELISA method revealed positivity only in 7.74%
