The objective of this study was to investigate the possible role of platelet activating factor in testicular ischemic injury. Materials and Methods: Five groups of 6 male Sprague-Dawley rats were studied, including group 1-nonoperated controls, group 2-sham operated controls, group 3-those that underwent administration of 10 micro g./kg. exogenous platelet activating factor into the left testicular artery, group 4-those that underwent 4 hours of testicular ischemia and group 5-those that received pretreatment with 0.4 mg./kg. of the platelet activating factor antagonist CV-6209 intravenously before 4 hours of testicular ischemia. Ipsilateral and contralateral testes were examined histologically and seminiferous tubular diameters were measured. Results: Exogenous platelet activating factor administration in group 3 and 4 hours of ischemia in group 4 resulted in a similar extent of histological degeneration of the experimental testicle. Pretreatment with CV-6209 in group 5 resulted in a marked decrease in hemorrhagic discoloration, vascular congestion and histological changes noted with ischemia in group 4. Conclusions: The results of this study suggest that platelet activating factor has a biochemical role in tissue injury associated with testicular ischemia. Also, administration of a platelet activating factor antagonist before the ischemic event decreases seminiferous tubule degeneration.
