Ejaculatory disorders: epidemiology and current approaches to definition, classification and subtyping

Topic Paper


Ejaculatory disorders (disorders of emission, ejaculation and orgasm) are the most frequent sexual complaint. Conventional algorithms on ejaculatory disorders are based on an organic or psychogenic dichotomy, with the latter being traditionally considered the main etiological cause. The scope of this review is to propose a new classification of ejaculatory disorders, with special emphasis on epidemiology and subtyping of the most frequent: premature ejaculation (PE). There is growing agreement on definition, diagnosis, and treatment options. In many cases, ejaculatory disorders can be classified by psycho-neuro-uro-endocrine symptoms. Epidemiological data, new classifications and subtyping, together with new diagnostic procedures and the availability of pharmacological aids, place this topic in the mainframe of sexual medicine. This will soon demolish the barriers to seeking help perceived by patients suffering ejaculatory disorders.
