[Study of anti-DR antibodies in sterility and infertility (author's transl)].

The presence of anti-DR antibodies with lymphocyte cytotoxicity test was studied in five groups of patients: 50 males with no history of blood transfusions who comprised the control group, 44 contraceptive-using women, 55 pregnant women, 41 primary sterile and 47 infertile patients. The high and similar degree of sensitization found in both pregnant and sterile patients lead us to the conclusion that anti-DR antibodies are not a cause of sterility and that spermatozoa are highly immunogenic. The biological significance of the antibodies is discussed.
