  sperm motility
     The results showed that glycerol-sucrose cryoprotective media had better effect on cryoprotection of spermatozoa than that of traditional glycerol protective medium, and appropriately increasing the concentration of sucrose and decreasing the concentration of glycerol could improve sperm motility, and especially benefit to preserve sperm linear motility at 12h postthawed.

The effects on frozen-thawed sperm survival rate of 16 different cryoprotective media containing different ratio of glycerol (0%, 2.5%, 5% and 7%) and sucrose (0,25,50 and 100 mmol/L) were compared. The results showed that glycerol-sucrose cryoprotective media had better effect on cryoprotection of spermatozoa than that of traditional glycerol protective medium, and appropriately increasing the concentration of sucrose and decreasing the concentration of glycerol could improve sperm motility, and especially benefit to preserve sperm linear motility at 12h postthawed. Using 5% glycerol combined with 50 mmol/L sucrose as cryoprotective medium, the sperm survival rate at 0, 6, 12h postthawed was 85.38%, 51.22%, 33.38%, respectively, the linear moving sperm survival rate was 83.74%, 33.33%, 18.38% respectively.

Aim: To observe the effect of Chinese traditional medicine Guanyu-liquid on spermatocidal contraception. Methods: The sperm motility,the sperm activity rate and the sperm density were observed at 20 s?1 min?15 min?30 min?60 min after mixing semen with Guanyu-liquid.The effect of the Guanyu-liquid on the cervical mucus and penetrability of sperm in the mucus were observed. Results: When the concentration of the Guanyu-liquid was 16.7%, the sperm motility dropped from Ⅳ to Ⅰ,the sperm activity rate from 70%...

Aim: To observe the effect of Chinese traditional medicine Guanyu-liquid on spermatocidal contraception. Methods: The sperm motility,the sperm activity rate and the sperm density were observed at 20 s?1 min?15 min?30 min?60 min after mixing semen with Guanyu-liquid.The effect of the Guanyu-liquid on the cervical mucus and penetrability of sperm in the mucus were observed. Results: When the concentration of the Guanyu-liquid was 16.7%, the sperm motility dropped from Ⅳ to Ⅰ,the sperm activity rate from 70% to 20% and the sperm penetrated 1.5 cm up in 120 min. When the concentration was 23.1%, the sperm motility dropped from Ⅳ to 0 in 15 min, the sperm penetrated 0.5 cm up in 120 min and the sperm density dropped from 50/HP to 20~40/HP.When the concentration was 28.6%, the sperm motility dropped from Ⅳ to 0 in 20 s and the sperm density was 0~5/HP.White deposition was observed and the cervical mucus could not be drawn. Conclusion: The guanyu-liquid can not only destroy human sperm,but change the character of the human cervical mucus.

目的 :观察中药方剂关玉液的杀精避孕作用。方法 :在精液中加入关玉液 ,并分别在不同时间观察精子活力、活率、密度 ;在宫颈粘液内加入不同量的关玉液观察对宫颈粘液的影响以及精子对此介质的穿透性。结果 :关玉液体积分数为 0 .16 7时 ,6 0min后精子活力由Ⅳ下降到Ⅰ ,活率由 70 %下降到 2 0 %,12 0min精子爬高 1.5cm ,远较正常对照 5cm短 ;关玉液体积分数为 0 .2 31时 ,1min时精子活率下降到 10 %,15min时下降到 0 ,2h精子爬高仅 0 .5cm ,精子密度由 5 0HP-1以上下降到 2 0~ 40HP-1;关玉液体积分数为 0 .2 86时 ,所有精子被立即制动 ,精子密度下降到 0~ 5HP-1。宫颈粘液和关玉液接触后产生白色沉淀 ,拉丝度消失。结论 :关玉液不但对精子的活动性和完整性具有明显的破坏作用 ,也能改变宫颈粘液的理化性质。

To evaluate current status of male sperm quality and compare with the data of 110 cases in 1980's from same laboratory,434 fertile man and 346 cases of man with uncertain sperm quality were examined.The results showed sperm quality was significantly declined.The changes were most obvious in the sperm counts and total number of sperm,which were decreased by 54.2%~98.9% and 39.7%~114.5% respectively.Among parameters of sperm quality,motility of sperm is most affected in overall motility,a level and a+b level motility,with...

通过对 434例有生育力、346例生育力不明男性的精液质量进行检测 ,并与同实验室 80年代前期 1 1 0例的数据相比较 ,评价目前男性精子质量的现状。结果表明 ,精子质量均明显降低 ,以精子数目中的计数和总数的降低最为明显 ,分别降低 5 4 .2 %~ 98.9%和 39.7%~ 1 1 4.5 % ;出现异常指标的异常百分率以精子活动性中的活动率、a级活力、a +b级活力最高 ,分别达到 1 8.4%~ 42 .3%、37.5 %~ 68.1 %、39.5 %~ 75 .2 % ;各指标在正常值范围内的比率仅占 33.6%和 2 6.0 %。因此 ,提出精液质量的普遍降低应引起足够重视。
