Human sperm mitochondrial function related to motility：a flow and image cytometric assessment
Human sperm mitochondrial function motility cytometric assessment
2009/2/23
Current evaluation of male fertility, routinely estimated by sperm count, motility, and morphology, provides only crude information about the fertility state of individuals. Both flow and image cyto...
The automated analysis of rat sperm motility following subchronic epichlorohydrin administration：methodologic and statistical considerations
rat sperm motility subchronic epichlorohydrin administration methodologic and statistical considerations

High-speed videomicrography was used to assess simultaneously the morphology and motility of seminal spermatozoa from 10 fertile donors and 10 patients being evaluated for infertility. In both don...
Correlation between defective motility（asthenospermia）and ATP reactivation of demembranated human spermatozoa
Human spermatozoa motility asthenospermia
2009/2/23
Human spermatozoa treated with 0.05% Triton X-100 to remove the cell membranes became immotile but flagellar movement was reinitiated by addition of 0.06 to 1 mM adenosine triphosphate (ATP). The pe...
