* The [[The_Ovary_-_Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]] is present on the [[Female_Reproductive_Tract_-The_Ovary_-_Anatomy_%26_Physiology|ovary]] and secreting large amounts of progesterone. The duration of this phase is directly related to the time that the [[The_Ovary_-_Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]] remains functional.

* High progesterone levels prompt the uterus to prepare a suitable environment for development of the embryo, and eventual attachment of the conceptus to the endometrium (implantation).
