X、Y精子分离与优生

Separation of Y spermatozoa and eugenics

本文建立并采用精子上游优选法成功地从精液中分离出高纯度的Ｙ精子，Ｙ精子的纯度从处理前的４９％上升到８８％，同时ａ级和ｂ级精子密度从处理前的４９．９％上升到９２．７％，精子呈现非常活跃的前向直线运动；正常形态的精子也从处理前的５２．９％上升到９７．４％，精子畸形率明显下降，精液质量得到了明显的提高。

This study first report that Y spermatozoa were separated Successful from semen using a rise technique in China.Overall density of Y spermatozoa was sign significantly enhanced from 49%in the unprocessed samples to 88%in the rise samples a and blevel sperms was significantly enhanced from 49.9%to 92.7%.Normal morphology was signicantly improved from 59.2% to 97.4%.Cellular debris and nonsperm cellar elements reduce distinct after process for rise technique.The rise technique is not a good therapeutic method to asthenozoospermia cases but a good seprated method of Y spermatozoa.
