Experience with the classification, diagnosis, and therapy of nonejaculatory intercourse

Twenty-one consecutive patients complaining of nonejaculatory intercourse were studied. Fifteen patients had anejaculation of various types, and sex therapy succeeded in 4 of 7 cases. Three patients had retrograde ejaculation that could be corrected by ephedrine sulfate in two cases having a neurologic cause. In one of three patients having nonemission, ejaculation was restored after stopping the drug thioridazine. A juvenile diabetic patient was discovered to have nonemission and not retrograde ejaculation. A classification of the disorders leading to nonejaculatory intercourse based on pathogenetic and clinical data is presented, including anejaculation, retrograde ejaculation, nonemission, and aspermia.
