Absorption activity of the blood group substances in various fractions of split ejaculates from man.
Antigens of the ABO system have been determined in the various fractions of split ejaculates from three A and two O (H) men who were secretors. The activity of the antigen was determined by a hemagglutination inhibition test. Within a split ejaculate the various fractions contained almost the same antigen activity, indicating that the antigens were secreted from all the glands contributing to the seminal plasma.
