Abstract: The sperm production (milt volume and spermatozoa concentration) and sperm motility characteristics (percentage of motile spermatozoa and duration of motility) were measured in order to assess the milt quality between hormone A (sGnRH-a with domperidone) and hormone B ( sGnRH-a with domperidone and Benzyl alcohol) stimulated African catfish, Clarias gariepinus. Six male broodstock were used, three were injected with hormone A and three with hormone B intramuscularly, eight hours after injection these fish were dissected to obtain their milt and the milt parameters were examined. Results showed that hormone A stimulated C. gariepinus produce more milt and the spermatozoa were more active than the hormone B simulated C. gariepinus.
