The measurement of the pressure elucidated that the vas deferens repeated autonomic contraction. This contraction was not the so-called peristalsis but the entire portion of the vas deferens contracted simultaneously. Stimulation of the hypogastric(More)
The effects of psychotropic drugs on ejaculation in dogs and on brain monoamines in dogs and rats were investigated. The results obtained in this study indicate that ejaculation is activated by the dopaminergic system in the brain, and that dopamine in the anterior hypothalamus is closely related to the occurrence of ejaculation.
The effects of 5-HTP and pCPA on manually induced ejaculation in dogs and on brain monoamines in dogs and rats were investigated. From the results obtained in this study it was concluded that the serotonergic system in the brain is the mechanism which inhibits the occurrence of ejaculation. Considered together with the results obtained in our previous(More)
