The role of anxiety in premature ejaculation: a psychophysiological model.

Despite the prevalence of premature ejaculation and the success in its treatment, researchers have yet to offer a compelling, empirically based theory regarding its nature or etiology. This study explored a model that argues that anxiety may not be necessary for the existence of this dysfunction. Fifteen premature ejaculators (PEs) and 17 nonpremature ejaculators (NPEs) engaged in self-stimulation to orgasm both in the laboratory and at home. The following specific hypotheses were tested: Compared to NPEs, PEs would demonstrate (i) shorter orgasmic latencies, both in the lab and at home, and (ii) equally accurate estimates of these latencies. Results offered strong support for both hypotheses. These findings, and those derived from a questionnaire completed by subjects, were seen as consistent with a psychophysiologic model of premature ejaculation. According to this model, the role of anxiety is seen as variable, interacting with the somatic vulnerability of the individual to determine orgasmic latency.
