A diagram showing the role of various stimuli from the female reproductive tract in sperm hyperactivation. Activation of CatSper (Ca2+ channel) by different stimuli mediates intracellular calcium influx into the flagellum resulting and stimulate flagellar beating thereby enabling penetration into the viscous mucus. Also, there is a subsequent release of stored Ca2+ at the midpiece region of the spermatozoa following CatSper-mediated Ca2+ influx thereafter promoting hyperactivated motility
