这是对大学临床医院 19 年期间收集的临床经验的回顾性研究。根据世界卫生组织标准对精液样本进行分析。在手淫后尿液中进行精子计数。数据以尿液中精子总数（TSNU）表示，并使用逆射精指数。根据研究样本中是否存在精子，将患者分为四组：a）精液和尿液中； b) 仅在尿液中； c) 仅存在于精液中； d) 既不在精液中也不在尿液中。对照组包括非逆射精患者。后射精患者是指TSNU优于3.8×106且RI优于2.16%的患者。在诊断后射精时，仅手淫后尿液中存在精子是不够的。所提议的指数加上尿液中的精子总数和精液量可以识别真正的后射精患者。
This is a retrospective study of clinical experience collected at the University Clinical Hospital over a 19-year period. Semen samples were analyzed according to WHO criteria. In the postmasturbatory urine, sperm count was performed. Data were expressed as total sperm number in urine (TSNU) and using a retroejaculation index. Patients were categorized into four groups according to the presence of sperm in the studied samples: a) in semen and urine; b) only in urine; c) only in semen; d) neither in semen nor in urine. A control group included nonretroejaculator patients. Retroejaculator patients are those whose TSNU is superior to 3.8 × 106 and the RI superior to 2.16%. While diagnosing retroejaculation, the only presence of sperm in the postmasturbatory urine is not adequate. The proposed index added to total sperm number in urine and semen volume may identify true retroejaculator patients.
