Histomorphology of ampulla of vas deferens of Gaddi goat and Gaddi sheep

The study was conducted on the accessory genital gland of male adult Gaddi goat and Gaddi sheep (24 each) to record histomorphology of ampulla of vas deferens. The ampulla was a distinct dilatation near termination of the vas deferens. The ampulla showed pseudostratified columnar lining epithelium. In its propria- submucosa tubulo-alveolar glands were present which included presence of alveoli, tubules and solid end-pieces. The lumen of alveoli and tubules showed masses of spermatozoa and secretions. Apical borders of lining epithelium showed apical blebs and protrusions suggestive of secretory activity. Tunica muscularis consisted of 2 distinct layers, i.e. inner circular and outer longitudinal. Tunica adventitia consisted of loosely arranged meshwork of collagen, elastic and reticular fibres along with blood vessels and autonomic ganglia. The histomorphology of the ampulla of vas deferens was more or less similar in both Gaddi goat and Gaddi sheep.
