Histological study on the vesicular glands of castrated and non-castrated bucks

Abstract

The present study was investigated the histological structure of the vesicular glands of eight mature castrated and noncastrated zaraibi bucks (4 animals/ each group). Generally, the vesicular gland of bucks was compact and lobulated gland. It was covered by a muscular capsule sending fibro-muscular septa dividing the gland into irregular unequal lobules. Each lobule was formed of numerous secretory acini and few amount of inter-acinar connective tissue stroma. Each lobule had a central collecting sinus to collect the secretions from the different acini. Both secretory acini and central collecting sinuses were lined mainly with pseudostratified columnar epithelium that was consisted mainly of secretory columnar cells and few small basal cells. The secretion was released into the acinar limen via apocrine mode. The castrated bucks showed more connective tissue and less acinar components in comparison to non-castrated bucks. Such finding represents the histological difference between the vesicular gland of castrated and non-castrated bucks that pointed out the effect of castration on structure of the vesicular gland.

Characterization of vesicular glands, study of vesiculitis and its association with other accessory sex glands in bulls

“…The presence of vacuoles in columnar and basal cells is also described in several species such as buffaloes, bulls, goats, (Ghonimi et al, 2014b;Adhikary et al, 2015;Emam et al, 2016) but were not mentioned in swine nor in horses (Badia et al, 2006;Scheeren et al, 2018), which suggests that it is a characteristic of the vesicular glands of ruminants.…”

“…The glandular epithelium is classified as pseudostratified, with the presence of columnar secretory cells as the main and basal cells sparsely distributed among the columnars, this is the description also used for other species (Ghonimi et al, 2014b;Adhikary et al, 2015;Emam et al, 2016) except for horses that have stratified epithelium (Scheeren et al, 2018).…”

“…The prevalence of vesiculitis varies greatly in herds depending on the age of the animals, production system, diagnostic methods and even the breed of the animals (Bagshaw and Ladds, 1974;Cavaliere and Van Camp, 1997;Martínez and Barth, 2007;Rovay, et al 2008;Gonzalez, et al 2019). The routes of infections can be ascending, descending or hematogenous, as well as congenital anomalies can predispose to the appearance of this pathology (Dargatz, et al, 1987;Cavaliere and Van Camp, 1997;Foster, 2009).…”

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

“…In the majority of cases, sperm mix with secretions from these glands. When they were first activated during sexual stimulation, their secretions appeared as fine droplets in the urethral meatus of the erect penis (Emam et al, 2016).…”

Comparative analysis of male reproductive accessory glands in bats Histiotus velatus (Vespertilionidae), Molossus rufus (Molossidae), and Peropteryx leucoptera (Emballonuridae)

“…Seminal vesicles are paired glands that produce and act as a reservoir of seminal fluid (Emam et al, 2016) and, thus, are associated with the production and secretion of various substances, such as neutral mucins and protein‐bound sialomucins (Gadegone & Sapkal, 1983) and a large amount of fructose (Crichton et al, 1981; Krutzsch et al, 1976; Mokkapati & Dominic, 1976; Rajalakshmi & Prasad, 1970). In bats, these glands are described as being located laterally to the ampullary glands, with both having a very similar structure (Martin et al, 1995).…”
