Spermatozoa were aspirated from the proximal vas deferens of five men with persistent anejaculation which could not be overcome by using a vibrator or electro-ejaculation. Three men had spinal cord injury, one man had undergone a pelvic lymphadenectomy, and in one of them the aetiology was unknown. Fairly good numbers of spermatozoa (from 7.5 to 170 million) with progressive motility from 24 to 75% were obtained from all the eight microsurgically performed aspiration attempts. In vitro fertilization (IVF) was successful in seven attempts. Eight embryo transfers (six with fresh and two with frozen embryos) resulted in three pregnancies. The pregnancy rates, 37% per aspiration and 37% per embryo transfer, show that in this small group of patients, aspiration of spermatozoa from the vas deferens followed by IVF-embryo transfer is a promising method in the management of infertility caused by persistent anejaculation.
从五名持续性不射精男性的近端输精管中吸取精子，这些男性使用振动器或电射精均无法克服不射精问题。三名男性患有脊髓损伤，一名男性接受了盆腔淋巴结清扫术，其中一人病因不明。在所有八次显微手术吸取尝试中，均获得了数量相当可观的精子（750万至1.7亿个），其进行性运动能力为24%至75%。七次体外受精（IVF）尝试成功。八次胚胎移植（六次新鲜胚胎移植和两次冷冻胚胎移植）导致三次怀孕。每次吸取的妊娠率为37%，每次胚胎移植的妊娠率为37%，这表明在这一小群患者中，从输精管吸取精子后进行IVF-胚胎移植是治疗持续性不射精所致不孕症的一种有前景的方法。
