* In the Uterus, capacitation is initiated with some phagocytosis occuring.

* In the Oviduct, capacitation is completed and sperm show hyperactive motility.
* In the Oviduct, capacitation is completed and sperm show hyperactive motility.
* Sperm attach to the cillia of the epithelium in the isthmus of the oviduct to form a functional reservoir. Only thousands from the initial millions in the ejaculate form this store, as 5-98% may be eliminated by retrograde flow or phagocytosis in the early female tract.
* At the Uterotubal Junction, the acrosome reaction occurs and the spermatozoon penetrated the oocyte in fertilization with the formation of male and female pronuclei.
