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 x 10(6) 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.
这是一项对大学临床医院19年间收集的临床经验进行的回顾性研究。精液样本根据世界卫生组织标准进行分析。对自慰后尿液进行精子计数。数据以尿液中总精子数（TSNU）表示，并使用逆向射精指数。根据研究样本中精子的存在情况，将患者分为四组：a）精液和尿液中均有；b）仅尿液中有；c）仅精液中有；d）精液和尿液中均无。对照组包括非逆向射精患者。逆向射精患者是指那些TSNU高于3.8×10⁶且RI高于2.16%的患者。在诊断逆向射精时，仅自慰后尿液中存在精子是不够的。所提出的指数加上尿液中总精子数和精液量，可能会识别出真正的逆向射精患者。
