    Description / Table of Contents: Résumé L'étude ultrastructurale de la spermatogénèse chezT. spiralis a permis de retrouver chez cette espèce les caractères morphologiques observés dans la lignée mâle chez la plupart des Nématodes, c'est-à-dire absence de flagelle chez le spermatozoïde, absence de reconstitution de l'enveloppe nucléaire après divisions méiotiques, structure atypique du centriole. Elle a permis de situer le spermatozoïde par rapport aux classifications antérieurement proposées.
    Notes: Abstract The ultrastructural study of spermatogenesis inT. spiralis demonstrated the main characteristics of the male germ cells in the class Nematoda, i.e. lack of flagella, lack of reconstitution of the nuclear envelope after the meiotic divisions, and atypical structure of the centriole. The spermatozoon ofT. spiralis was compared with previous classifications of the Nematoda spermatozoa.
