In the Saharan gerbil Meriones libycus, live trapped in the south west of Algeria, castration, carried out during the breeding season (Winter–Spring), induced, 50 days later, important modifications in adrenal gland activity. The adrenal weight and cortex volume increased by 11.7% and 25.0% respectively, with hypertrophy of reticularis zona (+57%, P<0.001) and hypotrophy of fasciculata zona (−13.4%, P<0.001) while glomerulosa exhibited o...

Orchidectomy performed during breeding season (winter) in the adult male gerbil, Gerbillus tarabuli, live trapped in its natural biotope in Béni Abbès area (30°7 N., 2°10 W.) in algerian Sahara desert, induced 50 days later, important weight, histological and hormonal changes on the adrenal gland.Adrenal weight increases by 69.7% (P=0.06) and adrenal cortex height by 48.6% (P=0.00) with hypertrophy of reticularis ...

The effect of gonadectomy and gonadal hormone replacement on the adrenal cortex activity was studied in the adult male sand rat Psammomys obesus, a diurnal gerbillid rodent living in Beni-Abbes area, in the Algerian Sahara desert (30°7 N, 2°10 W). Animals freshly captured were orchiectomized during the breeding season and some animals received testosterone oenanthate (75 μg per 40 μl olive’s oil) twice a day during 7 days, 3 weeks after gonadect...
