title: Risperidone-induced absence of ejaculation.
abstract: The absence of ejaculation in two patients treated with risperidone is described. This side-effect has rarely been reported. The mechanism responsible for ejaculation dysfunction in risperidone treated patients is unclear, but might be due to the alpha1-adrenergic antagonist action of the drug.
