What is a corpus luteum?

An ovary's corpus luteum is a collection of cells. During the first trimester of pregnancy, it is in charge of producing the hormone progesterone. In females, the corpus luteum is essential for establishing and maintaining pregnancy.

It is a yellow, hormone-secreting body that develops in the ovary at the site of the sac that has discharged after the egg has reached maturity during the process of ovulation. It is located in the female reproductive system. The granulosa cells that border the follicle begin to accumulate lipids and yellow pigments right after ovulation, which causes the development of lutein cells, which make up the corpus luteum.

Progesterone and estrogen are secreted by the corpus luteum. In the event of fertilization, they are crucial in creating changes in the uterus that make it more favorable for embryo-implantation; otherwise, it becomes dormant after about 14 days, resulting in menstruation.
