* After ovulation, the wall of the ruptured follicular cavity folds in.
* Slight haemorrhage occurs at the site of ovulation and fills the former cavity.
* This is known as the '''Corpus Haemorrhagicum'''.
* As the blood is resorbed, a solid '''Corpus Luteum''' is formed by proliferation of granulosa and theca intera cells as well as blood vessels.
* In the non-pregnant animal, corpora lutea are transient structures.
* Cyclic corpora lutea undergo proliferation and vascularisation directly after ovulation.
* The corpora lutea then regress and degenerate into a connective tissue scar, the '''Corpus Albicans'''.
* If the ovum is fertilised, the corpus luteum remains fully developed and active throughout at least part of the pregnancy.
* Corpora lutea produce progesterone.
* Progesterone prepares and maintains the uterus for implantation of the fertilised ovum.
