* In the [[Female_Reproductive_Tract_-The_Cervix_-_Anatomy_%26_Physiology|cervix]], sperm must travel through privileged pathways.  This serves to eliminate non-motile sprem and remove some abnormalities.

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

* 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.
