A corpus luteum cyst or luteal 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 does not often occur in women over the age of 50, because eggs are no longer being released after menopause. Corpus luteum cysts may contain blood and other fluids.
A luteal cyst is a cyst that forms after ovulation, from the corpus luteum (the remnant of the ovarian follicle, after the ovum has been released). [2] A luteal cyst is twice as likely to appear on the right side. [2] It normally resolves during the last week of the menstrual cycle. [2] A corpus luteum that is more than 3 cm is abnormal.

In a general blood test, a marked decrease in hemoglobin levels can be seen (in the anemic and mixed forms of ovarian apoplexy). Pelvic ultrasound reveals in the affected ovary a large corpus luteum cyst with signs of hemorrhage in it and/or free fluid (blood) in the abdominal cavity. Because ovarian apoplexy is an acute surgical pathology ...
The follicle first forms a corpus hemorrhagicum before it becomes a corpus luteum, but the term refers to the visible collection of blood, left after rupture of the follicle, that secretes progesterone. While the oocyte (later the zygote if fertilization occurs) traverses the fallopian tube into the uterus, the corpus luteum remains in the ovary.
During a pregnancy, the corpus luteum remains on the ovary releasing progesterone which will maintain a state of uterine quiescence and close the cervix until the delivery of the fetus. Alternatively if no implantation of a blastocyst occurs, the corpus luteum is degraded to a corpus albicans (scar tissue) by PGF2α released by uterine ...
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
The corpus luteum (the remains of an ovulated ovarian follicle) is responsible for the development of maternal behavior and lactation, which are mediated by the continued production of progesterone by the corpus luteum through some or all of pregnancy. In most species, the corpus luteum is degraded in the absence of a pregnancy. However, in ...
On occasion an ovarian cyst can rupture and give rise to internal hemorrhage. This may occur during ovulation or as a result of endometriosis . If the pregnancy test is positive, consider pregnancy related bleeding (see obstetrical hemorrhage ), including miscarriage and ectopic pregnancy .
