Gonadal Response to Psychosocial Stress in Male Tree Shrews (Tupaia belangeri) Morphometry of Testis, Epididymis and Prostate

Abstract: Male tree shrews (46 animds in all) were kept under distinct social conditions. Two kinds of controls were investigated: isolated animals as well as males out of female/male couples. Comparing these two groups only little isolation effect was observed. With the other individuals, initially isolated, dyads were formed which coexisted for 7 or 50 days. In a third group of dyads, after 50 days of coexistence social circumstances were aggravated for 5 more days by providing only half of the cage. All dyads establi… Show more

“…The reduction in plasma testosterone in subordinates is consistent with previous data in Syrian hamsters, where nine encounters with a dominant opponent suppresses plasma testosterone in subordinates (Huhman et al, 1991). Similarly, in many other species, including rats, tree shrews, primates, and humans, chronic stress has been shown to reduce plasma testosterone (Fischer et al, 1985; Kreuz et al, 1972; Razzoli et al, 2006; Rose et al, 1971; Tamashiro et al, 2004). Thus, in our model the maintenance of subordinate status for 14 days produces changes in basal plasma testosterone similar to chronic stress.…”
