Abstract
1. 1. Aromatase activity was measured in striatal and hypothalamic regions of the brain of the male ring dove throughout its breeding cycle. 2. 2. The enzyme activity in the anterior hypothalamus and hyperstriatum was significantly reduced in broody birds. A reduction in plasma LH and the number of spermatogonia per tubule cross-section were also observed at this time. 3. 3. The results support the view that testosterone is involved in the control of aromatase activity in the anterior hypothalamus and hyperstriatum. 4. 4. The enzyme activity in the posterior hypothalamus, paleostriatum and archistriatum showed no changes throughout the breeding cycle, indicating that other factors in addition to testosterone are involved in controlling the enzyme in these tissues.
