- The corpus luteum is a temporary endocrine structure that forms in the ovary following ovulation.
- It is composed of theca and granulosa cells that have undergone luteinization.
- The corpus luteum secretes progesterone and estrogen, which are essential for the maintenance of the uterine lining and the preparation for pregnancy.
- If pregnancy does not occur, the corpus luteum will regress and be replaced by a corpus albicans.
- If pregnancy does occur, the corpus luteum will continue to grow and function until the placenta takes over the production of progesterone and estrogen.
