RESUMEN
Introducción: La eyaculación precoz en el humano es una de
las disfunciones sexuales más comunes en la población mundial,
el conocimiento de la neurobiología de esta disfunción a través de
modelos animales es importante debido a que con estos modelos se
pueden proponer mejores opciones terapéuticas como tratamiento
para tratar esta disfunción. Nuestro grupo de investigación ha
desarrollado un modelo innovador, la Arena de Selección Múltiple de
Pareja (ASMP), en la cual se ha demostrado que las ratas macho en
este modelo animal eyaculan más rápido, de tal forma que esta arena
podría ser útil para evaluar diferentes fármacos que puedan retrasar
la eyaculación precoz en el humano.
Objetivo: El objetivo de este trabajo fue demostrar que la
administración la respuesta de Dapoxetina retrasa la eyaculación
rápida de ratas macho, cuando son evaluadas en la ASMP.
Métodos: Se realizaron dos pruebas de conducta sexual masculina
en la Arena de Selección Múltiple de Pareja (ASMP) a dos grupos
de ratas que fueron tratadas con el Vehículo y con 30 mg / kg de
Dapoxetina respectivamente.
Resultados: Los machos tratados con Dapoxetina, aumentaron
significativamente el número de montas y número de intromisiones
que requieren para eyacular, así mismo la latencia de intromisión y de
eyaculación cuando se compara con el grupo vehículo.
Conclusiones: Los machos que son tratados
con Dapoxetina en la ASMP dejan de comportarse
como eyaculadores rápidos.
