Testicular Activity of Bat, Taphozous longimanus During the Prebreeding and Breeding Period

Taphozous longimanus (Hardwicke) is a continuous breeder as males show full spermatogenic activity throughout the year. Microscopic study of testis reveals that immature, pre-breeding and sexually active males occur round the year. The testis shows variations in its structure during the different stages of breeding activity. In the pre-breeding period, testis shows various stages of spermatogenesis up to spermatid stage and in the breeding period, testis shows vigorous spermatogenesis and spermiogenesis.
