Human Spermatozoa Motility

This movie shows normal human spermatozoa motility and the response to the photo-release of progesterone.

Spermatozoa showing different types of responses to photorelease of progesterone, monitored at 30 frames/s. The flash for progesterone photorelease was at 5 s.

Both spermatozoa hyperactivation and the acrosome reaction are regulated by progesterone signalling, through activation of kinases present in the spermatozoa. These two processes appear to use different signalling pathways.

Molecular

CatSper - cation channel of spermatozoa flagellum, calcium influx in response to progesterone through tyrosine phosphorylation mechanism. PMID 24813608
Slo3 - a potassium ion channel sets the membrane potential, in mouse allows potassium ions to leave spermatozoa and shifts the membrane voltage to more negative.
- Mouse Slo3 channel opened in response to a decrease in the concentration of protons within the sperm (increase in pH).
- Human Slo3 channel controlled by changes in the levels of calcium ions. PMID 24670955
