Describe the corpus luteum

The corpus luteum is a temporary endocrine structure that develops from the ruptured ovarian follicle after ovulation. It is primarily made up of granulosa and theca cells, which have undergone a process of luteinization in response to luteinizing hormone (LH) released during ovulation.

The corpus luteum is responsible for producing progesterone, a hormone that helps prepare the uterine lining for implantation of a fertilized egg and supports early pregnancy. If fertilization does not occur, the corpus luteum will regress and eventually degenerate, leading to a drop in progesterone levels and the shedding of the uterine lining during menstruation.

The corpus luteum is essential for reproductive function in females and plays a critical role in maintaining menstrual cycles and supporting early pregnancy.
