Reproduction is a high priority function of all mammalian species. Strategies used to perpetuate species vary greatly, but in general they evolved to improve the success of survival of the offspring. The reproductive state of an individual at any particular time reflects an integration and coordination of both external and internal signals and not just a simple response to a single environmental factor. I Many mammals are seasonal breeders and respond to annual climatic changes by adaptive alterations in physiological as well as in histoarchitechtural status in anticipation of the coming season. The switching on and off of reproductive functions during the annual breeding cycle of bats is the most striking example of such photoperiodically induced process.Although Chiropterans are the second largest order of mammals, detailed reproductive patterns and their associated changes in the Sertoli cell have been documented only in few species. Hence, present investigation was carried out on Taphozous kachhensis and Pteropus giganteus giganteus of Bramhapuri Forest Range (20060’ 80.42'N and 79086 13.36' E) in Chandrapur district of Maharashtra, India Maharashtra, India.
