Every time you ovulate, a menstrual cycle fresh corpus luteum develops, and when you no longer require it to produce progesterone, it disintegrates.
Luteinizing phase
The corpus luteum, which is made up of ovarian cells, releases progesterone and a tiny amount of estrogen after ovulation. As a result, the uterine lining thickens in preparation for pregnancy.
If the oocyte is not fertilized, the corpus luteum stops secreting hormones within 14 days following ovulation, and the resulting corpus albicans scar develops inside the ovary.
