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. [6] [8]
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 ...
Vaginal ultrasound showing a corpus luteum in a pregnant woman, with a fluid-filled cavity in its center If the egg is fertilised and implantation occurs, the syncytiotrophoblast (derived from trophoblast ) cells of the blastocyst secrete the hormone human chorionic gonadotropin (hCG, or a similar hormone in other species) by day 9 post ...

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.
English: Vaginal ultrasound showing a 25 millimeter wide corpus luteum with a fluid-filled cavity in its middle (shown as dark in the image since it is anechoic). The rest of the ovary is seen at right, with 3 small follicles seen in the same plane. The woman was pregnant at 9 weeks of gestational age.
In 70% of cases, it is diagnosed in women between 20 and 39 years of age. The risk is greater during pregnancy and in menopause. Risk factors include increased length of the ovarian ligaments, pathologically enlarged ovaries (more than 6 cm), ovarian masses or cysts, and enlarged corpus luteum in pregnancy. [citation needed]
