The Barki goat have four sex glands: ampullary, vesicular, prostate, and bulbourethral. The ampullary gland is an enlargement of the terminal part of the ductus difference; its glandular part has branched tubuloalveolar glands, and its secretory alveoli are lined with a pseudostratifed epitheliumcomposed of cuboidal to columnar cells. The vesicular gland takes the appearance of a cluster of grapes, and the left vesicular gland is enlarged and higher than the right one. It presents as a lobulated tubulo-alveolar gland with wide intralobular space, which contains a secretory unit that is lined with pseudo-stratifed columnar epithelium, while the interlobular ductules are lined with the stratifed epithelium, and the interlobular duct is lined with simple cuboidal epithelium; moreover, the epithelium lining of the secretory part consists of tall columnar cells. The prostate gland consists of the disseminated part (pars disseminate), and it is enclosed by a connective tissue capsule, which is thin dorsally, thick laterally, and reduced in thickness ventrally. The prostatic acini are lined with simple cuboidal epithelium. The bulbourethral gland is similar in size to a walnut and is surrounded by a capsule; there are interlobular connective tissue septa that divide the gland into lobes and lobules of different sizes. The bulbourethral gland contains secretory units that are lined with mucous, tall columnar epithelium with basally located nuclei, and whose eosinophilic cytoplasm contain granular secretion. Keywords: Ampullary gland; Vesicular gland; Prostate gland; Bulbourethral gland; Goat Introducton The ruminant anatomy was generally concentrated on the bovine, particularly the ox, with limited comparative points to small ruminants, especially the goat. The goat belongs to the subfamily Caprinae, which is part of the Bovidae family, in the sub-order Ruminantia of the order Artiodactyla. In Egypt, the goat is considered as an important source of meat, milk, and hair. The male goat is a very familiar animal in the Egyptian farms. There are about 7 to 10 goat breeds in Egypt, such as Zaraibi, Barki (Sahrawi), Wahati, Sharkawi, and Black Sinai . 1 The three major breeds in Egypt are Ossimi, Rahmani, and Barki, which are characterized by a fat tail, a fleece of coarse wool, and their small-to-medium size. 1 There goats have four accessory sex glands; prostate, seminal vesicle, bulbourethral gland, and ampullary gland, as reported by, 2–9 while Pérez et al 10 reported that the pampas deer carry only three accessory sex glands: prostate, vesicular, and the ampullary gland. The lesser anteater also carries DOI: https://doi.org/ 11.51929/jms.37.4.2020 ISSN 2177-0298 only three accessory sex glands: prostate, seminal vesicle, and bulbourethral glands, as noted by Rossi et al . 11 The purpose of the present work is to describe the anatomical position and appearance of the accessory sex glands of the Barki (Sahrawi) male goat as well as the microscopic structure of theses glands as there is a little available information published about this topic. Then, we conducted a comparison between the obtained data and the previously published anatomical data about the accessory sex glands. The study of the accessory sex gland of the male goat is very important due to its significant role in the fertility rate. Materials and Methods Animals The present work was performed on 8 apparently healthy Barki male goats, whose weight was 25 to 30 kg and that were between 1 and 2 years old. The Barki male goats were collected from the goat farms in from the government of Matrouh and
