* There is immediate retrograde loss at the entrance to the [[Female_Reproductive_Tract_-The_Cervix_-_Anatomy_%26_Physiology|cervix]]/[[Female_Reproductive_Tract_-The_Uterus_-_Anatomy_%26_Physiology|uterus]] with phagocytosis by leukocytes.

* 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 [[Female_Reproductive_Tract_-The_Uterus_-_Anatomy_%26_Physiology|Uterus]], capacitation is initiated with some phagocytosis occuring.
* In the [[Female_Reproductive_Tract_-The_Uterus_-_Anatomy_%26_Physiology|uterus]], capacitation is initiated with some phagocytosis occuring.
* In the [[Female_Reproductive_Tract_-The_Oviduct_-_Anatomy_%26_Physiology|Oviduct]], capacitation is completed and sperm show hyperactive motility.
* In the [[Female_Reproductive_Tract_-The_Oviduct_-_Anatomy_%26_Physiology|oviduct]], capacitation is completed and sperm show hyperactive motility.
* Sperm attach to the cillia of the epithelium in the isthmus of the [[Female_Reproductive_Tract_-The_Oviduct_-_Anatomy_%26_Physiology|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.
