Development and hormonal control of territorial marking in the male mongolian gerbil (Meriones unguiculatus)

摘要: Male Mongolian gerbils were either castrated or sham operated at 30 days of age. Assessment territorial marking was carried out every 6 beginning 52 age and extending to 100 After each test, 10 intact males received 640 μg testosterone propionate subcutaneously; other animals castrates oil injections. The ventral sebaceous scent gland, used by the gerbil deposit sebum on objects during response, measured after test. Behavioral gland entirely absent in castrates. Relative controls, hormone-treated began earlier reached higher frequencies. Gland development also responsive hormone, but lagged behind activity.
