The corpus albicans in the ovary.

The corpus albicans is a structure that forms in the ovary after the corpus luteum degenerates. It is composed of fibrous tissue and appears as a white scar on the surface of the ovary. The formation of the corpus albicans is a normal part of the menstrual cycle in females.

Formation

The corpus albicans forms from the corpus luteum, which is a temporary endocrine structure in the ovary involved in the production of progesterone, estrogen, and other hormones. After ovulation, the corpus luteum develops from the remnants of the ovarian follicle that has released an oocyte. If pregnancy does not occur, the corpus luteum degenerates and is replaced by the corpus albicans.

Function

The corpus albicans itself does not have a direct function in hormone production. Instead, it serves as a marker of a previous ovulatory cycle. The presence of multiple corpora albicantia (plural of corpus albicans) in the ovary can indicate the number of ovulatory cycles a female has undergone.

Histology

Histologically, the corpus albicans is composed of dense connective tissue. It is primarily made up of collagen fibers and fibroblasts. Over time, the corpus albicans becomes less prominent as it is reabsorbed by the ovary.

Clinical Significance

The corpus albicans is generally not associated with any pathological conditions. However, its presence can be used in forensic medicine to estimate the reproductive history of a female. In some cases, the corpus albicans may be mistaken for other ovarian structures or pathologies during imaging studies.
