Most of proteins of boar seminal plasma are present in this medium under physiological conditions in the form of aggregates and not of monomers. In the present communication we have shown that not only spermadhesins, but also proteinase inhibitors participate in the formation of associated complexes. Proteinase inhibitors were found after gel chromatographic separation mainly in the fraction with the lowest relative molecular mass. The proteinase inhibitor with Mr 8 kDa was proved to form a heterodimer with AQN 1 spermadhesin under physiological conditions.
