Luteum

Luteum is a term used in anatomy and physiology to refer to a structure that forms in the ovary of a female mammal after the ovulation process. This structure, also known as the corpus luteum, plays a crucial role in the menstrual cycle and early stages of pregnancy.

Formation

The luteum forms in the ovary after the Graafian follicle releases an ovum during ovulation. The remaining parts of the follicle transform into the corpus luteum under the influence of luteinizing hormone (LH).

Function

The primary function of the luteum is to produce progesterone, a hormone necessary for the maintenance of pregnancy. If pregnancy does not occur, the luteum degenerates and stops producing progesterone, leading to the onset of menstruation.

Luteal Phase

The luteal phase is the latter part of the menstrual cycle or the earlier part of pregnancy during which the corpus luteum is present. The length of this phase varies among women but is generally about 14 days long.

Clinical Significance

The luteum is crucial in the regulation of the menstrual cycle and pregnancy. Its dysfunction can lead to infertility, miscarriage, and other reproductive disorders.
