Following process and their mechanism during fertilization in mammals.

 a. Rheotaxis

i.A sensing mechanism in which, the oocyte and its accompanying

cumulus cells secrete molecules that attract capacitated

sperm toward the egg during the last stages of sperm migration

b.  Chemotaxis

ii.It is a transient event, and sperm are given a relatively brief window of competence during which they can successfully fertilize the egg.

c.  Capacitation

iii.it is the ability to sense temperature difference and preferentially swim from cooler to warmer sites is found only in capacitated sperm.

d. Thermotaxis

iv.Sperm receive long-distance directional cues from the flow of liquid from the oviduct to the uterus and they will migrate against the direction of the flow—using CatSper calcium channels to sense calcium influx and monitor the direction of the current
