The aim of the present study was to establish the effects of platelet-activating factor (PAF) on selected movement parameters, plasmalemma integrity, capacitation process and acrosome reaction in cryopreserved boar spermatozoa. A positive effect of PAF addition to cryopreserved semen on sperm motility was demonstrated, particularly with the application of phospholipid concentration of 1 x 10-6M-1 x 10-5M. A moderate induction of plasmalemma damage of cryopreserved spermatozoa was observed when PAF was used at a low concentration (1 x 10-8M-1 x 10-7M). The rate at which PAF induced the process of capacitation was inversely proportional to its concentration in the sample (the highest for the concentration of 1 x 10-8M, and the lowest at 1 x 10-5M). In turn, the strongest induction of acrosome reaction of spermatozoa was observed in samples with the addition of PAF at a concentration of 1 x 10-7M. The results obtained suggest that the application of PAF supplement to post-thawed boar semen can be used as a laboratory test of the ability of spermatozoa to induce the acrosome reaction.
