“…Thus, the secretory cells of bulbo-urethral glands of bat, Rousettus show the ultrastructural characteristics which indicates that this gland is involved in synthesis and secretion of proteinaceous materials during the different phases of reproductive cycle. Similar secretory apparatus containing mitochondria, complexus golgiensis, endoplasmic reticulum and secretory granules has been reported in the secretory cells of bulbo-urethral gland of rat (Nielsen, 1976); human (Hellgren et al, 1982); Water buffalo (Abou-Elmagd & Wrobel, 1989) and boar (Badia et al, 2005(Badia et al, , 2006 supporting the present observations on bat.…”

SUMMARY:The present paper describes the ultrastructural characteristics of the bulbo-urethral gland (Cowper' glands) of the Indian fruit bat, R. leschenaulti during sexually inactive-breeding cycle. Cyclic histological changes during the seasonal breeding quiescence cycle are not well marked. There are no marked differences. The ultrastructural characteristic of the secretory epithelial cells of BulboUretrhal Gland gland have been studied during different phases of reproductive cycle. The secretory epithelial cells are characterized by the well-developed rough endoplasmic reticulum, extensive developed complexus golgiensis (Golgi apparatus) and mitochondria. Mitochondria with lamellate cristae are dispersed in the cytoplasm. Three different types of secretory granules can be identified on the basis of electron density. These granules are not of different types but they represent the different stages of granule maturation. The secretory products of bulbo-urethral gland of bat are released into lumen both by apocrine and merocrine modes. The functional significance of the secretions of the bulbo-urethral glands in reproduction is discussed.

“…These features tend to suggest a robust protein synthesis with the packaged secretory products released through the merocrine mechanism [3,33]. Merocrine secretion is established when the secretory granules are seen bulging or fusing to the apical cell membrane or are present in the luminal content [6,31]. From this study however, no structural evidence of merocrine secretion was seen in the coagulating gland.…”

“…While it is sparse and small in these rodents, it is large and abundant in the greater cane rat. According to Badia et al [6] the presence of abundant microvilli and coated vesicles have been associated with absorptive activity in the seminal vesicles. Although the significance of these well-developed microvilli in the coagulating gland of the cane rat is yet to be fully understood, the possibility of an absorptive role cannot be ruled out.…”

“…Glands that secrete by apocrine mechanism will normally have cells with apical blebs that contain secretory products and at different stages; some pinching off from the cell and discharged into the lumen and others still attached to the cells with few and scattered microvilli [32]. Although apocrine method of secretion have been described in the coagulating glands of most rodents [15,21,32] as well as in other glands in both animals and man [3,5,6,28], this secretion method always coexist with merocrine secretory activities in these glands [6]. The observations in the present study suggest apocrine secretory activities predominate in the coagulating gland of the cane rat.…”

The bulbourethral gland (or Cowper's gland) plays an important role for fertility. It is, therefore, essential to have quantitative data about the morphological and histomorphological structure of this gland in nonpathological conditions. In the present study, Holstein bull's bulbourethral glands were collected, and the volume of the glands, total epithelial cell number and epithelial cell's nuclear volume was estimated for the first time by stereological methods. The smooth fractionator technique for epithelial cell counting was used. Epithelial cell's nuclear volume was estimated on vertical sections. The mean number of the epithelial cells (coefficient of error; CE) and the mean epithelial cell's nuclear volume were found 322x10 7 (0.1) and 59.1 µm 3 (SD=3.7) respectively. Finally, the present studies stereological findings are in the acceptable range.

Bu çalışmada, Holştayn ırkı boğalardan alınan gl. bulbourethralis'lerin hacim, toplam epitel hücre sayısı ve epitel hücre çekirdeklerinin hacimleri ilk kez stereolojik metotlar kullanılarak hesaplandı. Epitel hücre sayımı için smooth fractionator tekniği kullanıldı. Epitel hücrelerin çekirdek hacimleri vertikal kesitler ile saptandı. Epitel hücrelerinin sayısı 322x10 7 ,(CE:0,1) ve epitel hücre çekirdek hacmi 59.1 µm 3 (SD=3.7) olarak hesaplandı. Elde edilen bulguların CE ve SD değerleri normal sınırlar içinde olduğu görüldü.
