[fr] Le but de cette revue est de décrire les techniques de congélation de la semence équine. Un rappel résumera la formation du spermatozoïde dans le testicule, son anatomie et sa physiologie en insistant sur les structures lésées pendant le processus de congélation et décongélation. Les techniques de congélation du sperme seront ensuite résumées dans différentes espèces et comparées avec celles utilisées pour la semence équine. Les critères actuels de qualité seront définis pour le sperme avant et après congélation en insistant sur la mobilité totale, progressive et les différentes définitions de ces concepts dans la littérature. Les autres méthodes d’analyse comme la cytométrie de flux seront présentées ainsi que leurs intérêts cliniques. Les prochains développements et progrès dans le domaine de la congélation seront enfin envisagés : la prédiction de la qualité du sperme congelé à partir du sperme frais, l’amélioration des dilueurs et la lutte contre les formes activées de l’oxygène.
