某地区5306例生育前精液质量与解脲脲原体感染情况探讨

目的探讨上海地区生育前精液质量现状及解脲脲原体(UU)对精子质量的影响。方法收集2014年1月至2015年11月符合标准的5 306例生育前男性行精液检查,按照年龄、UU感染情况进行分组,分析比较各组精液指标。结果精液pH值(7.27±0.14),精液量(3.15±1.42)mL,精子浓度(57.51±40.22)×106/mL,精子总数(172.83±134.90)×106,A级与B级精子总和(38.50±17.54)%,总活力(46.36±20.08)%,活动精子总数(89.86±92.82)×106。20~29岁年龄组男性精子总活动力为(49.60±20.70)%,活动精子总数为(93.40±95.83)×106,大于其余各组。2 311例(43.55%)UU阳性,UU阳性组精子总数、活动精子总数、精子浓度、A级精子率、A+B级精子率、精子总活力、精浆酸性磷酸酶、精浆α-糖苷酶及精浆果糖明显低于UU阴性组(P0.01),UU阳性组精液酸碱度及精浆锌明显低于UU阴性组(P0.05)。结论上海地区生育前男性精液质量不良,UU在生育前检查具有重要的作用。

Semen quality and urogenital Ureaplasma urealyticum infection in 5 306 preconception males in one district

Objective To investigate the semen quality and the influence of urogenital Ureaplasma urealyticum infection in pre‐conception males in Shanghai .Methods From Jan ,2014 to Nov ,2015 ,5 306 preconception males in our andrology department were received semen analysis .The difference of semen index between ages and urogenital Ureaplasma urealyticum infected or not were analyzed .Results The average pH value was(7 .27 ± 0 .14) ,the average volume was(3 .15 ± 1 .42)mL ,the average sperm concen‐trationwas(57.51±40.22)×106/mL,theaverageoftotalspermcountwas(172.83±134.90)×106 ,theaveragevitalityratioof grade(A+B) sperm was(38 .50 ± 17 .54)% ,the average motile sperm ratio was(46 .36 ± 20 .08)% ,the average of total motile sperm count was(89 .86 ± 92 .82) × 106 .Motile sperm ratio of preconception males from twenty to twenty nine was(49 .60 ± 20 .70)% ,total motile sperm count was(93 .40 ± 95 .83) × 106 ,which was greater than other ages .Ureaplasma urealyticum turned to positive in 2 311 cases was (43 .55% ) .There were statistically significant differences in total sperm count ,total motile sperm count ,sperm concentration ,vitality ratio of grade A sperm ,vitality ratio of grade(A+B) sperm ,motile sperm ratio ,seminal acid phosphatase ,seminalα‐glucosidase and seminal plasma fructose between positive and negative samples(P<0 .01) .There was differ‐ence in pH and seminal plasma zinc between positive and negative samples(P<0 .05) .Conclusion The sperm quality of preconcep‐tion males in Shanghai is not encouraging ,urogenital Ureaplasma urealyticum infection in preconception men is very important .
