【 摘 要 】

Although erectile dysfunction has recently become the most well-known aspect of male sexual dysfunction, the most prevalent male sexual disorders are ejaculatory dysfunctions. Ejaculatory disorders are divided into 4 categories: premature ejaculation (PE), delayed ejaculation, retrograde ejaculation, and anejaculation/anorgasmia. Pharmacologic treatment for certain ejaculatory disorders exists, for example the off-label use of selective serotonin reuptake inhibitors for PE. Unfortunately, the other ejaculatory disorders are less studied and not as well understood. This review revisits the physiology of the normal ejaculatory response, specifically explores the mechanisms of anejaculation, and presents emerging data. The neurophysiology of the ejaculatory reflex is complex, making classification of the role of individual neurotransmitters extremely difficult. However, recent research has elucidated more about the role of serotonin and dopamine at the central level in the physiology of both arousal and orgasm. Other recent studies that look at differing pharmacokinetic profiles and binding affinities of the α1-antagonists serve as an indication of the centrally mediated role of ejaculation and orgasm. As our understanding of the interaction between central and peripheral modulations and regulation of the process of ejaculation increases, the probability of developing centrally acting pharmaceutical agents for the treatment of sexual dysfunction approaches reality.
