Abstract
Comparative histology and histochemistry of pituitary gland, pineal body, adrenal gland, thyroid gland and Leydig cells of testes were studied in the normal and vasectomized male goats. The normal goats were grouped under prepubertal (3-4 months), circunpubertal (6-7 months) and postpubertal (10-18 months) animals. The prepubertal vasec tomy was done at 3 months of age while postpubertal vasectomy was conducted at the age of 9 months. From vasectomized goats, the tissues were collected after 1, 3 and 9 months of operations.
5.1 PITUITARY GLAND (Glandule pituitaries)
The capsule was mainly composed of collagen fibers with a few reticular and elastic fibers. The stroma was rich in reticular fibres. The sinusoidal capillaries were distributed the gland. Histochemically, the capsule and stroma were positive for PAS and acid mucosubstances. The capsule and stroma in the vasectomized goats did not differ from the normal goats.
Para distalis adenohypophysis was composed of solid or tubular cell cord. The average cell density per m² area increased with the advancing age of the animals. Statistically the average cell density per m² area in the vasectomized goats did not differ from the corresponding normal values. Both orangeophil and carminophil were identified in the acidophil cells of the goat.
