生殖道解脲支原体感染对精液的影响

Effect of ureaplasma urealyticum on semen quality

目的 研究男性生殖道解脲支原体感染对精液的影响。方法 对 76例不育病人和 44例生育男性的精液进行解脲支原体培养和精液分析 ,按解脲支原体培养结果分组 ,阳性组 5 1例 ,阴性组 6 9例 ,对精液量、精子密度、活率、活力、pH值、液化时间、正常形态率、畸形率、死亡率进行比较。结果 不育病人 76例中 43例解脲支原体阳性 ,阳性率 5 6 .6 % ,明显高于生育男性的 18.2 % (8/ 44 ) ;解脲支原体阳性组的精子密度、活率、活力、正常形态率明显低于阴性组 (P <0 .0 5 ) ;pH值、液化时间、死亡率、畸形率明显高于阴性组 (P <0 .0 5 ) ,而精液量两组间无明显差异 (P >0 .0 5 )。结论 生殖道解脲支原感染 ,对精液多项参数有影响 。

Objective To investigate the effect of ureaplasm urealyticum(U.U) on semen quality. Methods ureaplasma urealyticun in semen was cultured and semen analyzed for 76 cases with infertility and 44 cases with fertility. Classied into groups according to the results of ureaplasma urealyticum culture, 51 cases were involved in the positive group, 69 cases in negative group, compared with semen quantity, sperm dersity, survival rate,vitality, pH value, liquefacient duration, normal morphologic rate,teratic rate, death rate, Results Among 76 cases with infertility, 43 were positive in ureaplasma urealiticum, making up 56.6%.obviously higher than that of fertile males (18.2%); spermdensity, vitality,survival rate and normal morphologic rate in the positive group of ureaplasma urealyticum were remarkably lower than those of the negative group( P <0.05) ,and PH liquefacient duration, death rate and teratic rate were apparently higher than those in the nagative group ( P <0.05), and there was not obvious difference for semen quantity between two groups ( P >0.05), Conclusion The genital infection of ureaplasms urelyticum has effect on the multiple parameters of semen, and semen quality as a whole decreases.
