“…Recent studies have indicated marked morphological and functional variability of these glands in bats, including the fusion of prostatic lobes in some species; a lobulated pattern, very similar to that observed in rodents, in others; and the absence of a seminal vesicle (Beguelini, Góes, Rahal, Morielle‐Versute, & Taboga, ; Beguelini et al, ; Christante et al, ; Martins et al, ; Negrin et al, ; Puga, Beguelini, Morielle‐Versute, Vilamaior, & Taboga, ; Puga et al, ). In view of the great variation observed in these glands in bats, together with the lack of a description of these glands in one of the most important and representative bat species in Brazil, this study aims to analyze and characterize the composition, anatomy, histology, histochemistry, and ultrastructure of the male RAGs in the bat, Artibeus lituratus (Phyllostomidae: Chiroptera).…”

“…Despite its wide geographical radiation and advances in studies using evolutionary approaches, some aspects of the reproductive biology of bats remain poorly explored, especially those related to the accessory glands of the male genital system (Beguelini, Puga, Taboga, & Morielle‐Versute, 2016; Puga et al, ). Reproductive accessory glands (RAGs) are organs that form part of the male genital system and consist mainly of seminal vesicles, prostate, and bulbourethral and ampullary glands.…”

Bats are distributed worldwide from tropical to temperate regions. Despite their wide geographical radiation and advances in studies using evolutionary approaches, aspects related to the reproduction of these animals remain poorly explored, especially those related to the male reproductive accessory glands (RAGs). Thus, the aim of this study was to analyze the morphophysiology of the male RAGs in the bat Artibeus lituratus. The RAGs in A. lituratus are composed of a compact intra-abdominal glandular complex, consisting of the prostate with two prostatic regions (ventral and dorsal), plus Littre glands and a pair of extra-abdominal bulbourethral glands. The ventral region of the prostate has an epithelium with variable morphology, due to its holocrine type of secretion. In contrast, the dorsal region has a typical cubic-to-columnar pseudostratified epithelium. Both regions contain two cell types, basal and secretory cells. Similar to the epithelial morphology, the secretion also varies, with the ventral region containing numerous PAS-positive globular vesicles, whereas the dorsal region has a more fluid, hyaline and PAS-negative secretion. Littre glands are dispersed in the connective tissue of the urethra, while the bulbourethral glands are located in the penile root, both glands with cubic-to-columnar pseudostratified epithelium and globular PAS-positive secretion. The results demonstrate that the RAGs of A. lituratus are composed of two prostatic regions, ventral and dorsal, and urethral and bulbourethral glands, with no seminal vesicles. Each prostatic region has unique and distinctive characteristics, with the ventral region presenting an exclusive holocrine nature and the dorsal region having similarities to the ventral prostate of rodents.

“…Despite the unique morphology and physiology (undefined epithelium, absence of reactivity to acid phosphatase and holocrine nature—Puga et al, ), the prostatic ventral region was highly conserved both within the Phyllostomidae and in other families of bats, such as the Molossidae (Christante et al, 2014) and Vespertilionidae (Negrin et al, ). However, the dorsal portion of the prostate appears to have evolved differently in each phyllostomid subfamily, containing two distinct regions (dorsolateral and dorsal) in the Carollinae ( C. perspicillata ), Glossophaginae ( G. soricina ) and the Phyllostominae ( P. discolor ) and only one region (dorsal) in the Stenodermatinae ( A. planirostris —Puga et al, ; and P. lineatus ) and the Desmodontinae ( D. rotundus ).…”

“…The bats were aged as adults, based on the body weight, complete ossification of the metacarpal‐phalangeal epiphyses, wear of the teeth (De Knegt et al, ), the positioning of the testes and the presence of sperm within the testes, cauda epididymis, and/or prostatic urethra (Beguelini et al, ; Puga et al, ).…”

This study aimed to morphologically characterize and compare the male reproductive accessory glands (RAGs) of bats belonging to the five Brazilian subfamilies of the family Phyllostomidae (Carollia perspicillata-Carollinae; Desmodus rotundus-Desmodontinae; Glossophaga soricina-Glossophaginae; Phyllostomus discolor-Phyllostominae and Platyrrhinus lineatus-Stenodermatinae). The study demonstrated that the RAGs of phyllostomid bats were comprised of a pair of extra-abdominal bulbourethral glands and an intra-abdominal complex, composed of paraurethral glands and a prostate with two (Desmodontinae and Stenodermatinae) or three (Carollinae, Glossophaginae and Phyllostominae) different regions, with the absence of the seminal vesicles; this pattern possibly evolved from a process of compaction of the prostatic regions from an ancestor with three regions.

“…Nevertheless, testicular weight and GSI showed no difference between periods for any species. Other studies showed no differences in body weight throughout the year for S. lilium bats in the Atlantic Forest biome or for Artibeus planirostris bats in the Cerrado biome (Puga et al, 2014).…”

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.
