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
