Flow Cytometric Sperm Analysis. For this reason, it is considered to be a cause of male infertility. Asthenospermia may also be associated with sperm autoimmunity. Further work would be the building of a lab-on-a-chip type system that could integrate sample preparation, biological or chemical reaction, and data analysis in miniaturized channels or chambers for assisted reproduction applications. The first is an accumulation assay in which sperms sense the chemoattractant gradient and accumulate near or at its source. However, the time of sperm screening and the channel depth could be increased to further enrich the sperms in the outlet.
Glycogen synthase kinase-3a gsk3a , a potential sperm motility regulatory gene was predicted to be targeted by miRa, which was further supported by luciferase reporter assays, since a significant decrease of luciferase activity was detected upon ectopic overexpression of miRa.
