Corpus albicans

Corpus Albicans is a structure found in the ovary, specifically in the Graafian follicle, after the ovule has been released and the corpus luteum has degenerated. It is a small, white, scar-like structure that represents the final stage in the life cycle of the follicle.

Structure

The Corpus Albicans is a small, white, scar-like structure in the ovary. It is the remnant of the corpus luteum after it has ceased its progesterone production and has degenerated. The size of the Corpus Albicans can vary, but it is generally small and can often be difficult to see without magnification.

Function

The primary function of the Corpus Albicans is to mark the site of a previously active corpus luteum. It does not produce hormones or have any other known function. However, its presence can be used to determine whether an ovary has previously released an ovule.

Formation

The Corpus Albicans forms from the corpus luteum after the luteal phase of the menstrual cycle. If pregnancy does not occur, the corpus luteum will cease its production of progesterone and begin to degenerate. This process is known as luteolysis. The remaining cells will then be replaced by connective tissue, forming the Corpus Albicans.

Clinical significance

The presence of a Corpus Albicans can be used to determine whether an ovary has previously released an ovule. This can be useful in the diagnosis of certain conditions, such as polycystic ovary syndrome (PCOS), where the ovaries may not regularly release ovules.
