* After ovulation, the wall of the ruptured follicular cavity folds in.
* When the dominant antral follicle ovulates, slight localised haemorrhage occurs at the site of ovulation and fills the former cavity.
* The small amount of bloody tissue can be observed by the naked eye.
* This is known as the '''Corpus Haemorrhagicum'''.
* Loss of fluid from the antral cavity causes the follicle to collapse into many folds.
* As a result, some granulosal and thecal layers are pushed into the apex of the ruptured follicle.
* This protrusion of tissue and ruptured blood vessels forms a structure known as the '''Corpus Haemorrhagicum'''.
* Following this, the theca interna and granulosa cells differentiate into large and small luteal cells.
* As the blood is resorbed, a solid '''Corpus Luteum''' is formed by proliferation of granulosa and theca intera cells as well as blood vessels. This remains on the surface of the ovary.

* In the non-pregnant animal, corpora lutea are transient structures.
