This paper describes a structural and histological study of the pre-anal glands of Hemidactylus flaviviridis. Only males possess these glands, which have a tubuloacinar structure. They are holocrine in nature and become hyperactive during the breeding period. Thus they may be involved in the production of pheromones for socio-sexual communication.
