Either of the following symptoms must be experienced on almost all or all occasions (approximately 75%‐100%) of partnered sexual activity (in identified situational contexts or, if generalized, in all contexts), and without the individual desiring delay: 1. Marked delay in ejaculation. 2. Marked infrequency or absence of ejaculation. B. B. The symptoms in Criterion A have persisted for a minimum duration of approximately 6 months. C. C. The symptoms in Criterion A cause clinically significant distress in the individual. D. The sexual dysfunction is not better explained by a nonsexual mental disorder or as a consequence of severe relationship distress or other significant stressors and is not attributable to the effects of a substance/medication or another medical condition. Operationalisation Criteria of time‐to‐ejaculate, inability to ejaculate, distress, satisfaction … Lack of operationalized criteria Given that most sexually functional men ejaculate within about 4‐10 minutes following intromission [1], a clinician might assume that men with latencies beyond 25‐30 minutes (21‐23 min represents about two SD above the mean) who report distress or men who simply cease sexual activity due to exhaustion or irritation qualify for this diagnosis. 1.

J Sex Med. 2005: 2:58-367 Classification ‐ Specify whether: • Lifelong: The disturbance has been present since the individual became sexually active. • Acquired: The disturbance began after a period of relatively normal sexual function. • Generalized: Not limited to certain types of stimulation, situations, or partners. • Situational: Only occurs with certain types of stimulation, situations, or partners. Classification ‐ Specify current severity: • Mild: Evidence of mild distress over the symptoms in Criterion A. • Moderate: Evidence of moderate distress over the symptoms in Criterion A. • Severe: Evidence of severe or extreme distress over the symptoms in Criterion A. Prevalence of DE Since the beginning of sex therapy, DE was seen as a clinical rarity Masters and Johnson [1]: 17 cases. Apfelbaum [2]: 34 cases Kaplan [3]: 50 cases However, based on clinical experiences, some urologists and sex therapists are reporting an increasing prevalence of DE 1. Masters WH, Johnson VE.

Characteristics • High levels of relationship distress, sexual dissatisfaction, anxiety about their sexual performance, and general health issues • Lower frequencies of coital activity [Rowland 2005] • A distinguishing characteristic: men with DE have little or no difficulty attaining or keeping their erections‐in fact they are often able to maintain erections for prolonged periods of time • Despite their good erections, they report low levels of subjective sexual arousal, at least compared with sexually functional men [Rowland 2004] CLINICAL ASPECTS Assalian Jannini McMahon Rowland Waldinger Evaluation of men presenting with DE should include a full medical/sexual history, a focused physical examination and any investigations suggested by these findings Recommendation Pathophysiology Psychogenic Inhibited EjaculationNEUROGENICInfective DE Urethritis Congenital Mullerian duct cyst Genitourinary tuberculosis interruptionWolfian duct abnormaility of the nerve supply to the Schistosomiasisgenitals • traumaticPrune surgicalbelly syndrome injury to the lumbarEndocrine sympatheticHypogonadism ganglia Neurogenic Diabetic autonomic Hypothyroidism • abdominoperitoneal surgery Causes neuropathy Medication Alpha-methyl Dopa Spinal cord injury• lumbar sympathectomy.

A clinical continuum Premature ejaculation Delayed ejaculation Mild Moderate Severe Anejaculation Lifelong DE, like lifelong PE, is considered to be a primarily a neurobiological variant, which may or may not secondarily lead to psychological or psychosocial distress.
