Effects of orchidectomy and male hormone administration on the adrenal of common myna, Acridotheres tristis.
When orchidectomized, the adrenals of semi-domestic, adult common myna, Acridotheres tritis atrophied. The cortical cord width and cortico-medullary ratio decreased and ascorbic acid and cholesterol contents of the adrenal increased significantly. Testosterone, depending upon the dose employed either restored the atrophic adrenals to normal condition or caused further atrophy of the glands of the castrated birds, suggesting a stimulatory effect on the adrenals at low and inhibitory at high dose levels.
