Encompassing a broad spectrum of conditions, ejaculatory dysfunction (EjD) includes premature ejaculation (PE), anejaculation(AE), and retrograde ejaculation (RE). This chapter discusses the incidence rate, diagnosis methods and treatment options available for treating EjD. Behavioral/psychological treatments, topical anesthetic agents, serotonin reuptake inhibitors (SSRIS) and phosphodiesterase (PDE)-5 inhibitors are the treatment options available for PE. Penile vibratory stimulation, electroejaculation, and surgical sperm extraction from the epididymis or testes are all successful methods for obtaining sperm for later use with ART in AE where the success rates of other methods are low. Common causes of RE can be categorized as anatomic, neurogenic, pharmacological, or idiopathic in origin. Anticholinergics, alpha-adrenergic agonists, or similar combinations may be used to modulate bladder neck activity but are not as effective as imipramine, which should be considered the first-line therapeutic agent for RE.
