Résumé Contexte L’utilisation de la cytométrie en flux (CF) pour évaluer la fragmentation de l’ADN des spermatozoïdes via la technique TUNEL (Terminal transferase dUTP nick-end labelling) a montré des incohérences par rapport aux analyses conventionnelles par microscopie fluorescente. L’hypothèse a été émise que les divergences observées pourraient être attribuées à la présence de corps apoptotiques qui peuvent être marqués à la mérocyanine 540 (corps M540). Afin de vérifier cette hypothèse et de déterminer la précision de notre évaluation interne des paramètres des spermatozoïdes, nous avons mesuré par CF à la fois la fragmentation de l’ADN des spermatozoïdes en utilisant le test TUNEL et l’oxydation de l’ADN des spermatozoïdes en utilisan...
