title: Antisperm antibodies and sterility: insoluble problem or perspective trend of research?
abstract: Conflicting opinions about the effects of antisperm antibodies on fertilization can be due to inadequacy of experimental approaches in evaluating the antisperm immunity. Detection of antisperm antibodies bound to the surface of live spermatozoa can be associated with aggregation of surface antigen-antibody complexes followed by metabolic activation of spermatozoa and acrosomal reaction, which impair cell resistance. New concept of antisperm immunity and its influence on reproduction can be formulated only after comprehensive studies of the mechanisms of spermatozoon response to binding of antisperm antibodies. Further improvement of quantitative assays of antisperm antibodies and evaluation of their effect on spermatozoon function should be aimed at selection of experimental conditions preventing changes in spermatozoa coated with antisperm antibodies during in vitro manipulations.
