Resumen:
The sexual behavior has anxiolytic-like effects in several procedures. There is a wide body of literature that suggests that one possible mechanism involved in this phenomenon is the increase of testosterones release produced by sexual situation. Findings of androgens exogenous administration support this hypothesis. In previous studies have been use different aversives stimulus, like electrics shocks, cold water immersion, etc. The aim of the present study is evaluated if the testosterones anxiolytic effect is also produced with the omission of an expected appetitive reinforcer. With this objective we realize a chronic administration of 25mg/kg testosterone in a consummatory extinction procedure to adult rats. The findings suggest that the subjects with testosterones administration show a faster extinction compared with control animals. The results are discussed in relationship with the emotional testosterones effects and the functional equivalence between aversive stimulus and omission of an appetitive stimulus.
