This paper describes our experience with retrograde vasal sperm aspiration (ReVSA) in anejaculatory patients with spinal cord injury. We performed 11 vasal sperm aspiration procedures on eight patients presenting with neurogenic anejaculation associated with spinal cord injury at our institute between 2004 and 2007. This procedure was conducted under local anesthesia with a spermatic block. A 24G needle was inserted into the vas in a retrograde fashion. Sperm-washing medium was gently injected into the proximal vas several times and collected. Aspirated sperm was cryopreserved for intracytoplasmic sperm injection. Adequate motile sperm was obtained from all patients. All couples underwent intracytoplasmic sperm injection; clinical pregnancies were achieved in eight cases (two ongoing pregnancies and the births of six healthy babies). Retrograde vasal sperm aspiration is a reliable method for the consistent recovery of sperm of sufficient quality to afford a high pregnancy rate and in sufficient quantity to permit cryopreservation of excess sperm for future use.

本文描述了我们对脊髓损伤所致不射精患者进行逆行输精管精子抽吸术（ReVSA）的经验。2004年至2007年期间，我们在本研究所对8例因脊髓损伤导致神经源性不射精的患者进行了11次输精管精子抽吸手术。该手术在局部麻醉加精索阻滞下进行。用24G针头以逆行方式插入输精管。将精子洗涤介质轻轻注入输精管近端几次并收集。抽吸的精子冷冻保存用于卵胞浆内单精子注射。所有患者均获得了足够数量的活动精子。所有夫妇均接受了卵胞浆内单精子注射；8例临床妊娠成功（2例正在妊娠，6例诞下健康婴儿）。逆行输精管精子抽吸术是一种可靠的方法，能够持续获取质量足够高、数量足够多的精子，以实现高妊娠率，并能保存多余精子用于冷冻以备将来使用。（《生殖医学与生物学》2008年；：115 - 118）
