精子密度：指每毫升精液中所含的精子数，是确定稀释倍数的重要指标。要求用血细胞计数板进行计数或精液密度仪测定

CASA检测，按上述方法，取10ul 精子悬液，上机检测。到底是取附睾头还是尾？

用3%KCL溶液，按比例稀释精子，10min后，用普通计数板计数，很简单的。

The tube was vortexed briefly and a 100 lL aliquot of the resulting suspension was placed in an IDENT-stain tube (Hamilton-Thorne Biosciences) with 100 lL distilled water. The tube was again vortexed and incubated for 3 min at room temperature. A 5 lL aliquot was placed on a 20 lm chamber slide (X-CEL; Hamilton-Thorne Biosciences), and spermatoazoa were counted using the IDENT option of the Oval Head Toxicology programme (Hamilton-Thorne Biosciences). A minimum of 40 scans per individual were recorded.

用casa仪呀

精子计数其实比较简单，可以浓度较高的盐水即可，如3%，然后上计数板，根据数左不数右，数上不数下的原则计数即可。个人浅见。

生理盐水稀释后加甲醛杀死后上细胞计数板慢慢数吧，

可以做流式技术吧

与楼上说的差不太多，不过稀释精液的不能用双蒸水吧，最好用PBS之类的缓冲体系，混匀后用甲醛等物质杀死精子，然后再用血细胞计数板计数
