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.
The corpus luteum secretes progesterone, which is a steroid hormone responsible for the decidualization of the endometrium (its development) and maintenance, respectively. It also produces relaxin , a hormone responsible for softening of the pubic symphysis which helps in parturition.
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]

The early embryo has 1–2 weeks in order to produce sufficient hCG in order to stabilize the endometrial lining to allow for blastocyst attachment. The dramatic increase in trophoblastic and corpus luteal hCG synthesis signals both blastocyst [ 5 ] and corpus luteal [ 6 ] production of P4, crucial for the maintenance of the endometrium .
The most common causes for adnexal masses in premenopausal women include follicular cysts and corpus luteum cysts. Abscesses can form as a complication of pelvic inflammatory disease . In postmenopausal women, adnexal masses may be caused by cancer , fibroids , fibromas , or diverticular abscesses.

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 ...
