虽然精子和卵子的运行与生育及不孕关系十分密切,但迄今人们对这一过程的了解还很不完全。雌性生殖道(FGT)平滑肌的收缩参与精子的运行,是基于以下事实:(1)射精后,精子在2～10分钟就到达输卵管,速度之快不能用精子本身的游动来解释。(2)子宫颈端放入碳粒,很快就被运送到输卵管。(3)用直接观察的方法可看到大鼠子宫的收缩推动精子在子宫角上、下移动。也有大量的资料表明卵子的运行与
Although the relationship between sperm and egg operation and fertility and infertility are very close, so far the understanding of this process is still incomplete. The contraction of smooth muscle in female reproductive tract (FGT) is involved in spermatozoon operation based on the following facts: (1) After ejaculation, sperm reach the fallopian tube in 2 to 10 minutes, and the rapidity can not be explained by sperm motility. (2) The end of the cervix into carbon particles, was quickly delivered to the fallopian tubes.
