Corpus luteum cyst Classification and external resources ICD-10 N83.1 ICD-9 620.1 MeSH D010048 A Corpus luteum cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst rarely occurs at age 50+, because eggs are no longer being produced in menopausal women.

Pathophysiology
This type of functional cyst occurs after an egg has been released from a follicle. The follicle then becomes a secretory gland that is known as the corpus luteum. The ruptured follicle begins producing large quantities of estrogen and progesterone in preparation for conception. If a pregnancy doesn't occur, the corpus luteum usually breaks down and disappears. It may, however, fill with fluid or blood, causing the corpus luteum to expand into a cyst, and stay on the ovary. Usually, this cyst is on only one side, and does not produce any symptoms.[1][2]
Presentation
It can however grow to almost 10cm (4 inches) in diameter and has the potential to bleed into itself or twist the ovary, causing pelvic or abdominal pain. If it fills with blood, the cyst may rupture, causing internal bleeding and sudden, sharp pain. Rarely it may cause the ovary to twist around the ovarian ligament and can cut off the blood flow to the ovary. This is known as ovarian torsion and cause pain and wamble symptoms.
Interaction with medication
The fertility drug clomiphene citrate (Clomid, Serophene), used to induce ovulation, increases the risk of a corpus luteum cyst developing after ovulation. These cysts don't prevent or threaten a resulting pregnancy.[3][4] Women on birth control pills usually do not form these cysts; in fact, preventing these cysts is one way the combined pill works.[5] In contrast, the progesterone-only pill can cause increased frequency of these cysts.
