HUMAN ABO BLOOD GROUP ANTIGENS ON SPERMATOZOA FROM SECRETORS AND NON-SECRETORS

Abstract

Washed spermatozoa from an O non-secretor have been incubated with seminal plasma from an A secretor and have been shown then to have developed the capacity of inhibiting anti-H and anti-A test solutions. This demonstration is in agreement with the findings of Edwards, Ferguson and Coombs (1964) who, in contrast to earlier workers, were unable to detect ABO blood group antigens on spermatozoa from non-secretors, though they were able to detect them on spermatozoa from secretor donors.
