【摘要】 应用快速化学比色法对20例生育男性和92例不育男性精浆唾液酸（SA）进行检测。结果精浆SA（X±smg／L）在生育组（1095．26±249．67）与不育组（1020．20±299．68）之间无显著性差异（P＞0．05）．但随精子数减少，精浆SA逐渐下降。糖浆SA在精子活率≤50％的不育者中为1171．80±351．96mg／L，在精子活率正常（＞50％）的不育者为864．99±362．61mg／L，二者存在显著性差异（P＜0．05）；阻塞性无精子症者糖浆SA（71221±152.4mg／L）明显低于分泌性无精子症患者（1207．57±251．80mg／L）。更多还原

【Abstract】 Using quick colorimetric analysis to determine the spermatic sialic acid(SA)contents in 92 cases of sterility and 20 cases of controls,the authors find the SA contents begin to descend gradually with the decrease in spermatozoon quantity though there is no remarkable difference (P>0.05)in the result of the SA contents (X±Smg/L),which are 1020±299. 68 in the cases of sterile semen and 1095. 26±249. 67 in controls. This datum shows the SA contents of semen are 1171. 80±351. 96mg/L in the cases of sterility with abnormal living rate of spermatozoa (≤50% )and 864. 99±362. 61mg/L with norma (>50% ). The aboves also have apparent difference (P<0. 05 % );and the SA contents of semen in the obstructive non-spermatic cases (712. 21±152. 64mg/L) are lower than in the secretory non - spermatic ones (1207. 57 ± 251. 80mg/L). At last, the authors realize that the determination of spermatic SA contents is an important parameter to ascertain the male bearing ability.更多还原
