Premature Ejaculation, Selective Serotonin Reuptake Inhibitor (ssri) Induced Delayed Ejaculation In The Framework Of The Emotional Motor System

Premature ejaculation has generally been considered a psychosexual disorder with psychogenic aetiology. Although still mainly treated by behavioural therapy, in recent years double-blind studies have indicated the beneficial effects of some of the serotonergic anti depressants (SSRIs) in delaying ejaculation. We describe here the europhysiology and the peripheral neuroanatomy of ejaculation and provide a review of the involvement of serotonin in the central nervous system in relation to serotonergic nuclei and their projections. A hypothesis of the role of 5-HT1A and 5-HT2C receptors in premature ejaculation is postulated.
