The corpus luteum in a non- pregnant woman usually lasts about 10 days after the egg leaves the ovary.
Corpus luteum is inside the ovaries and is shaped like a tiny sac that can hold a developing egg. It is made of two main type of cells, that is, follicuar theca cells and follicuar granulosa cell. A human hormone called human chorionic gonadotrophic [HCG] spurs these cells to make progesterone.
When the egg escapes the dominant follicle during ovulation, the sac breaks. If the egg doesn't get fertilized, corpus luteum will start to break down around 10 days after the egg leaves the ovary. Without the progesterone, your uterus won't go through the changes that support pregnancy and you will shed the lining during periods.
