Morphological examination of the accessory sex glands of the Barki bucks (Capra hircus)

Abstract

The present investigation was prepared to describe the accessory sex glands of the Barki bucks grossly and by light microscopy. There are four sex glands: ampullary, vesicular, prostate, and bulbourethral. The ampullary gland is an enlargement of the terminal part of the ductus deferens, its glandular part has branched tubuloalveolar glands, and its secretory alveoli lined with a pseudo-stratified epithelium composed 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. The vesicular gland is a lobulated tubuloalveolar gland with wide intralobular space and the gland contain a secretory unit which lined by pseudo-stratified columnar epithelium, and the interlobular ductules lined by the stratified epithelium, while the interlobular duct lined by simple cuboidal epithelium moreover, the 2 lining epithelium of secretory part consists of tall columnar cells. The prostate gland consists only of the disseminated part and is enclosed by a connective tissue capsule that was thin dorsally, thick laterally, and reduced in thickness ventrally. The prostatic acini are lined by simple cuboidal epithelium. The bulbourethral gland was similar in size to the walnut and surrounded by a capsule and there are interlobular connective tissue septa that divided the gland into lobes and lobules of different sizes. The bulbourethral gland contains secretory units lined by the tall simple columnar epithelium of mucous type with basely located nuclei and eosinophilic cytoplasm contain granular secretion. The gross and microscopic examination of the four accessory sex glands gave valuable information in the future pathology diagnosis of the accessory sex glands of the Barki bucks.

Histomorphochemical Studies on Accessory Glands of Iraqi Blackbuck (Caprus Hircus)

“…4). Alsafy et al (2021) found similar discoveries. Myoepithelial cells surround the alveoli and exert a contractile impact on the bulbourethral gland's alveoli, which helps explain why bulbourethral secretion is discharged into the urethra.…”

“…4). This was in contrast to (Alsafy et al, 2021). Camels have a seromucous bulbourethral secretion that responds favorably to PAS stain (Fig.…”

“…2). The epithelium of the gland is supported by the lamina propria mucosa, a loose connective tissue composed of collagen and smooth muscle fibers (Alsafy et al, 2021). In the buck, a simple columnar epithelium with oval nuclei lines the primary secretory duct of the seminal vesicle (Sarangi et al, 2021).…”

“…3). According to (Dyce et al, 2009), these alveoli are bordered with simple columnar epithelium (Alsafy et al, 2021) in ruminants of a small size. According to the current results, sections stained with PAS stain revealed the lining epithelium of the prostate gland duct converted into the pseudostratified columnar epithelium.…”

Investigation of male genital system anatomy in the New Zealand rabbit (Oryctolagus cuniculus L.)

“…Partes genitales masculinae externae is consists of the penis, which is the mating organ, the urethra masculina, which is responsible for the transport of semen in the penis, and the preputium that covers the penis (König & Liebich, 2015). There are studies on male genital tract organs in different animal species (Alsafy et al, 2021; Baygeldi et al, 2021; Erdoğan, 2011; Harem et al, 2019; Kırbaş Doğan et al, 2021;Pe'rez et al, 2013). There is also literature on the subject studied.…”
