摘要： 本文研究了宁夏汉族男性不育患者指长波动性不对称(FA)与不育的相关性。分析了宁夏汉族男性不育患者308例(原发组196例, 继发组112例)各指指长FA(2FA、3FA、4FA、5FA)及复合FA(CFA)的均值及其均值的差异性; 比较了指长FA与a+b级精子比率间的关系。结果表明: 1)原发组各指指长FA均值均高于继发组, 且2FA(P<0.01)、4FA(P<0.05)和CFA(P<0.05)有显著性差异; 2)原发组a+b级精子比率显著低于继发组(P<0.05); 3)原发组2FA分布在|L-R|≥0.04组显著增高(P<0.05), 2FA与a+b级精子比率呈高度负相关(P<0.001)。

Abstract: To investigate the relationship between fluctuating asymmetry (FA) of digit length and infertile men of the Han ethnic community from Ningxia, the mean values of fluctuating asymmetry (FA) of digits (2FA, 3FA, 4FA, 5FA) of 308 infertile men (primary sterility group totaled 196; secondary sterility group totaled 112) were studied. The relationship between 2FA and a+b ratio of sperm number were also analyzed, with the following results: 1) the primary sterility group had higher FA as compared to the secondary sterility group, with significant differences in 2FA (P<0.01), 4FA (P<0.05) and CFA (P<0.05); 2) the a+b ratio of sperm number was lower in the primary sterility group compared to the secondary sterility group (P<0.05); 3) there was a higher difference in the |L-R|≥0.04 on distribution of 2FA (P<0.05) and a significant negative relationship between 2FA and the a+b ratio of sperm number in the primary sterility group (P<0.001).
