摘要：En un artículo previo mostramos que, en ratas, la eyaculación produjo un efecto ansiolítico en una situación de frustración usando un procedimiento de contraste sucesivo negativo consumatorio (CSNc), que implica la reducción abrupta de un reforzador apetitivo. Los experimentos que presentamos tienen como objetivo evaluar si ese efecto se extiende a una situación que implica una estimulación socio-sexual. En el Experimento 1 se evalúa el consumo mediante el tiempo de contacto con el bebedero ante la devaluación del 32% al 4% de una solución azucarada en ratas machos con experiencia sexual previa. Antes del segundo ensayo de la devaluación, las ratas se dividieron en tres condiciones: acceso y eyaculación con una hembra receptiva, contacto visual-olfativo con una hembra receptiva y ningún contacto con hembras. Durante la segunda sesión de la fase de post-cambio, los dos primeros grupos consumieron una proporción mayor de la solución devaluada en relación con el grupo control. En el Experimento 2 se realiza el mismo tratamiento antes de colocar a los animales ante una prueba de campo abierto. Los machos sometidos a eyaculación o contacto visual -olfativo no se diferenciaron de los controles en la ambulación; sin embargo ambos grupos permanecieron en el área central significativamente más tiempo que los animales pertenecientes al grupo control. Estos resultados extienden el efecto ansiolítico de la eyaculación a la estimulación social-sexual en una condición de disminución de reforzadores apetitivos y en una situación de temor ante lugares novedosos.
其他摘要：Ejaculation has been shown to have anxiolytic-like effects in a consummatory Successive Negative Contrast situation. Present research was conducted with the main goal of replicating and testing whether ejaculation is a necessary factor to obtain anti-anxiety effects after socio-sexual stimulation in both a reward downshift situation and in an open field test. In Experiment 1, male rats were tested in the second post-shift session of a 32% to 4% sucrose solution downshift after having the chance of an ejaculation, visual-olfactory contact with a receptive female, or no contact with females. Similarly to treatments with anxiolytic drugs, increments in consumption after the initial consummatory reduction were equivalent for ejaculatory and visual-olfactory conditions relative to controls not exposed to females. In Experiment 2, the sEjaculation has been shown to have anxiolytic-like effects in a consummatory Successive Negative Contrast situation. Present research was conducted with the main goal of replicating and testing whether ejaculation is a necessary factor to obtain anti-anxiety effects after socio-sexual stimulation in both a reward downshift situation and in an open field test. In Experiment 1, male rats were tested in the second post-shift session of a 32% to 4% sucrose solution downshift after having the chance of an ejaculation, visual-olfactory contact with a receptive female, or no contact with females. Similarly to treatments with anxiolytic drugs, increments in consumption after the initial consummatory reduction were equivalent for ejaculatory and visual-olfactory conditions relative to controls not exposed to females. In Experiment 2, the same treatments were applied before males were placed in an open field. Ejaculators and visual-olfactory males did not significantly differ from controls in terms of general activity, though both groups had significantly more average time in central areas of the open field than the control group. Altogether, present experiments provided evidence that socio-sexual stimulation in male rats is a sufficient factor in reducing anxiety responses in a reward downshift situation. In addition, this anxiolytic-like effect of ejaculation and socio-sexual stimulation is extensive to novel context situations.
