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.
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 ...

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.
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, diagnosis must be confirmed rapidly, since delays between the event and surgical intervention increases the magnitude of blood loss ...
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]
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 hemorrhagicum ("bleeding corpus luteum") [1] is a temporary structure formed immediately after ovulation from the ovarian follicle as it collapses and is filled with blood that quickly clots. [2] After the trauma heals, the subsequent structure is called the corpus luteum (which in turn becomes the corpus albicans before degenerating ...
