Resumen

Supplementation with seminal plasma could improve the quality of cryopreserved boar semen. We have tested if a short incubation of post-thawed boar spermatozoa with 50% of homologous seminal plasma modify the levels of free radicals. We obtained five semen pools from frozen semen doses (three males) and evaluated the sperm viability (YOPRO1 or propidium iodide), the mitochondrial activity (Mitotracker deep red), the production of mitochondrial superoxide (MitoSOX) and the intracellular free radicals (CM-H2DCFDA) using flow cytometry. Samples were assessed just after thawing (control and adding 50% seminal plasma) and after 1 h of incubation at 37 °C. Incubation decreased viability, mitochondrial activity and mitochondrial superoxide production, with no significant effect of seminal plasma. The levels of intracellular free radicals did not change in the control, but they increased at 1 h in the 50% seminal plasma treatment. We could no detect a protective effect of seminal plasma in this study, but our results suggest an increase of intracellular free radicals with time. This could be associated to the stimulation of signalling pathways, which could be associated to the positive effects found in previous studies.
