Seasonal variation in the Histomorphogy, Micrometry and Histochemistry OF Seminal Vesicles of Gaddi goat and Gaddi sheep

The study was conducted on the accessory genital glands of male Gaddi goat and Gaddi sheep (24 each) to record the histology and histochemistry in the different seasons (spring, summer, autumn and winter). The seminal vesicles of Gaddi goat and sheep were compound lobulated, tubulo-alveolar glands. Besides tubules and alveoli, solid end-pieces were also found in gland. The diameter of the glandular end-pieces and epithelial height of the alveoli and tubules of all the glands were significantly higher during the autumn season; these measurements were more or less similar in the winter and spring and were least in the summer. The seminal vesicles were lined with pseudo stratified columnar epithelium with three types of cells “A, B, C” and showed a PAS-positive, diastase resistant substance in their epithelial cells which could be fructose. Cholesterol was also observed in epithelial borders and in secretion of the gland.
