Local production of antisperm antibodies in infertile women.

The presence and significance of locally produced antisperm antibody in 20 well-documented infertile patients has been investigated. Sera and vaginal washings both from patients and from fertile controls were examined for antisperm antibody by means of four methods. Antisperm antibody was detected in 25% of the washings taken from infertile patients, but in none of those from fertile women. Detection of antibody by the microimmobilization technique discriminated best between infertile and fertile women both in serum (P=0.0166) and in washings (P=0.0166). The results of this study support the concept that locally produced antisperm antibody contributes to conception failure in a subgroup of infertile women, and that the routine study both of sera and of vaginal washings of infertile patients has practical value.
