Cumulus oophorus

Cumulus oophorus (also known as discus proligerus) is a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation.

Structure

In the ovarian follicle, the cumulus oophorus is seen as a layer of cells surrounding the oocyte. The cumulus oophorus is composed of cumulus cells that are directly in contact with the oocyte and corona radiata cells that are adjacent to the cumulus cells and form a radiating crown around the oocyte.

Function

The main function of the cumulus oophorus is to supply the oocyte with vital proteins and to protect the oocyte during the process of ovulation. The cumulus oophorus also plays a crucial role in the fertilization process as it helps in the binding of the sperm to the oocyte.

Clinical significance

Abnormalities in the cumulus oophorus can lead to problems in fertilization and can be a cause of infertility.
