Corpus luteum cyst usually occurs due to overactivity of corpus luteum. There is excessive bleeding inside the corpus luteum. In spite of the blood filled cyst, the progesterone and estrogen secretion continues. As a result, the menstrual cycle may be normal or there may be amenorrhea or delayed cycle. It is usually followed by heavy and/or continued bleeding. It is then confused with a case of threatened abortion or else, if the intracystic bleeding is much, it may rupture producing features of acute intraperitoneal hemorrhage with clinical picture simulating disturbed tubal ectopic pregnancy.
It may often be associated with pregnancy and persists for about 12 weeks. Unless complicated, spontaneous regression is expected.
