生育与不育男性生育力指数的比较

Comparison of Fertility Index between Fertile and Infertile Male

目的:评估生育力指数(FI)在判断男性生育能力中的作用。方法:对不育组(n=124)和生育组(n=62)进行精液常规检查,并计算FI[FI=精子密度(106/ml)×精子活动力×精子正常形态率]。结果:生育组FI为13.23(24.16),高于不育组的5.69(10.62)(t=5.657,P=0.001)。生育组FI(P2.5,P97.5)的范围为2.06-56.85。结论:FI较单个精液参数更能客观反映男性生育能力,当FI<2.0时男性生育概率将下降。

Objective： To evaluate the effect of fertility index （FI） in judging male fertility. Methods： A total of 124 infertile male semen samples （infertility group） and 62 fertile male semen samples （fertility group） were tested for sperm routine analysis. And calculate as： FI= sperm concentration （10^6/ml）× sperm viability × sperm normal morphology rate. Results： FI in fertility group which was 13.23 （24.16） was higher than that in infertility group which was 5.69 （10.62） （t=5.657, P=0.000）. FI in fertility group （P25, P975） was 2.06-56.85. Conclusion： FI can reflect male fertility more impersonality than sperm parameters separately and the male fertility would decrease when FI〈2.0.
