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

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.

Risperidone-induced retrograde ejaculation: case report and review of the literature

Medication adherence with antipsychotics is adversely impacted by the burden of untoward adverse effects. In particular, sexual side-effects may interfere with compliance, but are often underreported by patients. Sexual dysfunction related to hyperprolactinemia is commonly described, but ejaculatory disturbance due to potent alpha1 adrenergic antagonism may also occur, and has been reported frequently with certain typical antipsychotics such as thioridazine, but rarely with atypical antipsychotics. Presented here is the case of a 51 year old male with schizophrenia who developed retrograde ejaculation on high dose risperidone therapy (8 mg/day) with prompt resolution of symptoms upon dose reduction. The absence of decreased libido or erectile dysfunction indicates that alpha1 adrenergic antagonism and not low serum testosterone due to hyperprolactinemia is the etiology for this side-effect. This case illustrates another mechanism for sexual adverse effects, and the need for routine inquiry into sexual dysfunction during atypical antipsychotic therapy.

Disorders of ejaculation

The physiology of ejaculation includes emission of sperm with the accessory gland fluid into the urethra, simultaneous closure of the urethral sphincters, and forceful ejaculation of semen through the urethra. Emission and closure of the bladder neck are primarily alpha-adrenergically mediated thoracolumbar sympathetic reflex events with supraspinal modulation. Ejaculation is a sacralspinal reflex mediated by the pudendal nerve. The most common ejaculation disorder is premature ejaculation, but there is little agreement regarding the definition of this disorder or its etiology, diagnosis, and treatment options. Premature ejaculation is in fact classically considered psychogenic in nature. However, recent data have demonstrated that prostatic inflammation/infection has been found with high frequency in premature ejaculation, suggesting a role of prostatic pathologies in the pathogenesis of some cases of failure of ejaculatory control. Rarer disorders are emission and ejaculation failure and urine contamination of semen. The new use of diagnostic procedures and the availability of pharmacological aids place this topic in the mainframe of medical sexology.
