Sixty-nine couples enrolled in 123 in vitro fertilization-embryo transfer cycles were categorized by percentage fertilization; the results of categorization were compared with those of computerized semen analysis carried out with the CellSoft semen analyzer. Four groups were established: group 1 had 75% fertilization or greater; group 2 had 34% to 74% fertilization; group 3 had 1% to 33% fertilization; and group 4 had 0% fertilization. Statistical differences in certain semen parameters (motility, linearity, and straight-line velocity) were found comparing groups 1 and 3 using the initial ejaculate. A significant number of patients in group 1 had all normal semen parameters, but no statistical difference could be found in group 3 or 4 because of variations in specific abnormal parameters in the groups. When the straight-line velocity-motile density (SLVMD) calculation was used, a significant difference was seen between group 1 and group 3 and between group 1 and group 4 (p less than 0.01); 65% of group 3 and 76% of group 4 had an abnormal SLVMD. SLVMD is a useful calculation to predict fertilization rates in vitro from the initial ejaculate.
69对参与123个体外受精 - 胚胎移植周期的夫妇按受精率进行分类；分类结果与使用CellSoft精液分析仪进行的计算机化精液分析结果进行比较。共分为四组：第1组受精率为75%或更高；第2组受精率为34%至74%；第3组受精率为1%至33%；第4组受精率为0%。使用初始射精样本比较第1组和第3组时，发现某些精液参数（活力、直线性和直线速度）存在统计学差异。第1组中有相当数量的患者精液参数全部正常，但由于第3组和第4组中特定异常参数的变化，未发现统计学差异。当使用直线速度 - 活动密度（SLVMD）计算时，第1组和第3组之间以及第1组和第4组之间存在显著差异（p小于0.01）；第3组的65%和第4组的76%的SLVMD异常。SLVMD是一种从初始射精样本预测体外受精率的有用计算方法。
