Ejaculatory dysfunction is a common complaint and is often associated with a reduced quality of life for sufferer and partner. The spectrum of ejaculatory dysfunction extends from premature ejaculation (PE) to delayed ejaculation (DE) and anejaculation. Over the past 20-30 years, the PE treatment paradigm, previously limited to behavioural psychotherapy, has expanded to include drug treatment. Multiple well-controlled, evidence-based studies have demonstrated the efficacy and safety of selective serotonin re-uptake inhibitors in delaying ejaculation, confirming their role as first-line agents for the treatment of lifelong and acquired PE. More recently, there has been increased attention to the psychosocial consequences of PE, its epidemiology, its aetiology and its pathophysiology by both clinicians and the pharmaceutical industry. DE and anejaculation are probably the least common, least studied and least understood of the male sexual dysfunctions. However, their impact is significant as they may result in a lack of sexual fulfilment for both the man and his partner, an effect further compounded when procreation is among the couple's goals of sexual intercourse. The causes of DE, anejaculation and anorgasmia are manifold. Numerous psychotherapeutic treatments are described for the management of delayed or anejaculation. Although some appear to be effective, none has been properly evaluated in large-scale samples. Treatment of DE or anejaculation with pharmacotherapy has met with limited success. No drugs have been approved by regulatory agencies for this purpose, and most drugs that have been identified for potential use have limited efficacy, impart significant side-effects or are yet considered experimental in nature.
射精功能障碍是一种常见的主诉,通常会降低患者及其伴侣的生活质量。射精功能障碍的范围从早泄(PE)到射精延迟(DE)和无射精。在过去的20 - 30年里,早泄的治疗模式从前仅限于行为心理治疗,现已扩展到包括药物治疗。多项严格对照、基于证据的研究证明了选择性5-羟色胺再摄取抑制剂在延迟射精方面的有效性和安全性,证实了它们作为治疗终身性和后天性早泄一线药物的作用。最近,临床医生和制药行业对早泄的心理社会后果、流行病学、病因学和病理生理学越来越关注。射精延迟和无射精可能是男性性功能障碍中最不常见、研究最少且了解最少的。然而,它们的影响很大,因为它们可能导致男性及其伴侣缺乏性满足感,当生育是夫妻性交目标之一时,这种影响会进一步加剧。射精延迟、无射精和性高潮缺失的原因是多方面的。有许多心理治疗方法被描述用于管理射精延迟或无射精。尽管有些似乎有效,但在大规模样本中都没有得到适当评估。用药物治疗射精延迟或无射精取得的成功有限。监管机构尚未批准任何药物用于此目的,大多数被确定有潜在用途的药物疗效有限、有明显副作用或本质上仍被视为实验性药物。
