“…Moreover, conservation strategies are currently urgent, as anthropogenic threats have already caused large reductions of certain populations, driving species toward local or global extinctions [5,6]. Despite those dramatic threats, bat semen preservation for assisted reproduction has seldom been addressed as an appropriate method for species and genetic conservation [7][8][9]. Such an approach would, however, appear most applicable in species breeding poorly in captivity and for which ex situ conservation is not a reasonable option.…”

“…The concentration and sperm viability found in L. yerbabuenae, compared with reports for the cauda epididymis of Artibeus jamaicensis (54.79 ± 88.14 x 10 6 ) and Sturnira llilium (51.80 ± 25.93 x 10 6 ) [38] indicate that L. yerbabuenae has a higher sperm concentration (108.50 ± 93.94 x 10 6 ). These differences in members of the same family may result from the different reproductive strategies that each species have, the first two species are bimodal poliestric, however L. yerbabuenae is seasonal monoestric [38].…”

Studies in reproductive age mammals show that the increase in fat content is inversely related to sperm quality in response to a decrease in testosterone levels. In turn the decrease in androgen concentration is related to morphophysiological involution in the testis and epididymis. However, the bat Leptonycteris yerbabuenae increases the body fat content previous the mating period, contrary to what was reported in most mammals. Therefore the aim of this study was to determine the importance of variation in fat content in L. yerbabuenae in relation to testicular and epididymal cycle; and sperm parameters. The results clearly show an increase in the fat content as it approaches the mating season. Also, there is an increase in the size of the testis and epididymis. In the post-mating months, both: fat and testis, decrease and the sperm cells were not presents. Leptonycteris yerbabuenae has a different behaviour to most mammals, accumulate fat while producing, transit and sperm storage could be happening. So, in this model, we must do studies that meet these processes emerging from that reported in other mammals.

“…There is very little information in the literature about bat sperm quality and morphology. Alvarez‐Guerrero et al () found higher percentages of morphologically normal sperm cells in A. jamaicensis (62%) and S. lilium (70%). Some authors affirm that both agriculture and urbanization may have negative effects on animal species population, providing a low‐quality habitat for reproduction (Battin, ; Schlaepfer, Runge, & Sherman, ).…”

“…In our study, A. lituratus is the largest species (65.1–67.7 g), followed by P. lineatus (20.5–25.7 g) and S. lilium (21.3–23.0 g), which have similar body weights. In other studies, similar weights were found for the three species ( A. lituratus ~65 g—Beguelini, Puga, Taboga, & Morielle‐Versute., ; Duarte & Talamoni, ; P. lineatus ~ 25 g—Beguelini, Puga, Taboga, et al, ; and S. lilium 20–22.6 g—Álvarez‐Guerrero, Medrano, & Moreno‐Mendoza, ; Morais, Barros, Freitas, Paula, & Matta, ) in other biomes (especially Atlantic Forest). The only difference between dry and rainy periods was in the body weight of S. lilium animals, which was higher in the dry period.…”

The aim of this study was to analyse the reproductive aspects of male bats of three common species of the Phyllostomidae family: Artibeus lituratus, Platyrrhinus lineatus and Sturnira lilium, during dry and rainy months in a specific area of the Cerrado biome. Body weight was significantly higher during the dry months for S. lilium. The gonadosomatic index (GSI) and testicular weight were not significantly different between dry and rainy periods. The tubular parameters were significantly bigger in A. lituratus than in the other two species during both periods. No difference in the tubular/interstitial ratio was observed in any of the species during both periods. In both periods, all sperm cells and germ cell developmental stages were visible on seminiferous tubules whereas sperm cells were observed in epididymides of all sampled animals. The percentage of morphologically normal sperm was low (35%–60%), with no difference between periods. Spermatozoa from A. lituratus presented a leaf‐shaped head, while the head was round‐shaped in the other two species. In conclusion, our data suggest that males from the three studied species did not present reproductive latency during the most critical weather periods (dry and rainy months) in the metropolitan region of Brasilia, Brazil.
