Ovarian chocolate cyst is caused by endometrial tissue growing in the ovary. Normal endometrium will undergo periodic changes, which will cause monthly menstruation. The endometrium in the ovary will also change periodically with the menstrual cycle, and the endometrium ectopic in the ovary will also have periodic bleeding, which occurs repeatedly. As a result, the blood accumulation in the ovary will gradually increase, and the blood will accumulate for a long time, and the liquid will gradually absorb, thus becoming thick. The old blood is like chocolate, so it is called the chocolate cyst of the ovary. Chocolate cyst of the ovary is a cyst caused by ectopic mucosal tissue in the ovary, so it usually has periodic abdominal pain and other uncomfortable symptoms. As the menstrual cycle changes, the chocolate cyst will gradually increase. When it increases to a certain extent, when the pressure in the cavity is high, the chocolate cyst will spontaneously rupture, causing the occurrence of pelvic and even abdominal endometriosis, And chocolate cyst is easy to lead to infertility, and it is generally recommended to give drug treatment or surgical treatment.
