Corpus Liteum - Cyst

Does anybody know anything about Cyst here?  i mean liteum corpus?  they said it ruptures and creates pains but its not harmful.  how true is that?

thanks a million for your reply. 

@gentledove :
Development and structure of corpus liteum :
The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or estrous cycle, following the release of a secondary oocyte from the follicle during ovulation. The follicle first forms a corpus hemorrhagicum before it becomes a corpus luteum, but the term simply refers to the visible collection of blood left after rupture of the follicle, and has no functional significance. While the oocyte (later the zygote) traverses the Fallopian tube into the uterus, the corpus luteum remains in the ovary.

The corpus luteum is typically very large relative to the size of the ovary; in humans, the size of the structure ranges from under 2 cm to 6 cm in diameter.

When egg is not fertilized/when you arent pregnant :
 corpus luteum stops secreting progesterone and decays (after approximately 14 days in humans). It then degenerates into a corpus albicans, which is a mass of fibrous scar tissue.
