Semen quality and urogenital Ureaplasma urealyticum infection in 5 306 preconception males in one district / 国际检验医学杂志

ABSTRACT

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 .
