The Chiroptera is a peculiar mammalian Order due the adaptations for flight and the peculiar habits of life. Although extensive radiation and is familiar with the issues of the evolutionary group, some aspects of reproductive biology, are still poorly explored, especially those related to the accessory glands of the genital system and the functional relationships of these glands with seasonal variations. Having been established as a research area of our research group, studies of bats in prostate appears to be an excellent field for studying evolutionary approach and reproductive biology. Thus, this study aims to evaluate the male accessory sex glands with emphasis on species representing three subfamilies of the family Phyllostomidae, namely Glossophaginae, and Carollinae Phyllostominae. Looking like a scene outline anatomical, histological and histochemical comparison of the male sex accessory glands with bases in detailed descriptions by testing macroscopic, microscopic and ultrastructural, taking into account the evaluation of the possible influence of seasonality and serum sex steroid hormone, on the glands throughout the year. To this end, adult male collected in the nature of the species Glossophaga soricina (Glossophaginae), Carollia perspicillata (Carollinae) and Phyllostomus discolor (Phyllostominae) during all months of the year, after collection of blood for serum hormone analysis, will be submitted to dissection and subsequent removal of the accessory sex glands and subjected to routine techniques for histological evaluations and ultrastructural. The qualitative and quantitative analysis at light microscopy and transmission electron and scanning will be performed and morphometric and stereological parameters will be subjected to statistical tests to investigate the specific differences of these standards throughout the year. Thus it will seek to draw comparisons in the family that will certainly contribute to the understanding of this gland in histophysiology neotropical Phyllostomidae.
