阴茎振动刺激与电射精在射精障碍中的应用

辅助生育技术较大程度地提高了不育症患者的生育潜力,但其中射精障碍患者的取精始终是一个难题,阴茎振动刺激(PVS)和电射精(EEJ)方法的发展,使其有了更好的治疗前景。PVS使用简单、无创、无需要麻醉,应推荐为首选,大约 80%存在完整射精反射弧(T10水平以上)的射精障碍者都能通过PVS获得顺行射精;几乎所有射精障碍患者,包括中枢神经和 /或外周神经损伤的患者都能成功使用EEJ取精。本文综述PVS和EEJ的适应证、使用方法及影响取精的因素等临床应用过程中需要注意的重点问题。

Penile Vibratory Stimulation and Electroejaculation in the Treatment of Ejaculatory Dysfunction

The fertility potential of infertile men can be enhanced to a great extent by the application of assisted reprodution techniques such as intrauterine insemination or in-vitro fertilization with or without intracytoplasmic sperm injection, but how to obtain semen from men with ejaculatory dysfunction remains a problem. The development and refinement of penile vibratory stimulation(PVS) and eletroejaculation (EEJ) have significantly brightened the prospects for the treatment of ejaculatory dysfunction. Because vibratory stimulation is non-invasive and easy to perform, and needs no anaesthesia, it is preferred by most of the patients to EEJ, and recommended to be the first choice of treatment for ejaculatory dysfunction. Approximately 80% of all ejaculatory dysfunciton men with an intact ejaculatory reflex arc (above T 10) can obtain antegrade ejaculation by PVS. Any condition which affects the ejaculatory mechanism of the central and/or perilheral nervous system including surgical nerve injury may be treated successfully by EEJ. The purpose of this review is to present the current understanding of PVS and EEJ procedures and their clinical use in men with ejaculatory dysfunction.
