The case of a patient with sleep-related painful erections is described. Insomnia and a slight depressive syndrome occurred along with a long history of this disorder. No physical abnormality was found. At a baseline recording of sleep electroencephalography (EEG) and nocturnal penile tumescence (NPT), a disturbed sleep pattern and impaired NPT were recorded. Attempts to treat the disorder with diazepam, amitriptyline, trimipramine, and biperidene did not prompt a stable improvement of the disorder, but a dosage of 25 mg clozapine was sufficient to achieve normalized sleep architecture, remission of the depressive symptomatology, and normalization of NPT. It is likely that marked sedation is the mode of action of clozapine.

Sleep related painful erection is a parasomnia occurring during rapid eye movement (REM) sleep. It is rarely dealt with in the literature, and is very often poorly understood. Because of repeated awakenings, it is interpreted as insomnia, and is attributed to anxiety. EEG recordings associated with nocturnal penile tumescence monitoring indicate the existence of disturbed sleep organization, with awakenings during REM sleep and frequent nocturnal erections, often unrelated to REM sleep. Though the pathophysiological mechanisms involved are not yet understood, an interpretation of sleep-related painful erections is proposed, based on the current understanding and physiology of diurnal and nocturnal erections.
