Summary. Saliva samples from 442 persons were tested for the presence of anti A and/or anti B saliva antibodies. The material was classified into two groups: 1. The ‘non‐immunized’ group comprised group O women with group O husbands, primiparous women with a group O child, nonparous women, and group O males. 2. The ‘immunized’ group comprised group O women with heterospecific pregnancies or group incompatible husbands. Chance immunization by A and B‐like substances from other sources was not considered as both groups would be subjected to these influences. Saliva antibodies were found more frequently in the immunized group than in the non‐immunized group. The difference between the two groups was statistically significant. If the figures for males were omitted from the non‐sensitized group the difference still remained highly significant. In the compatible group the number of pregnancies had no influence on the presence or absence of saliva antibodies. In the incompatible group there was a statistically significant decrease of saliva antibodies with the increase in the number of pregnancies. Explanations for these findings are discussed.
