Ovarian apoplexy is a sudden rupture in the ovary , commonly at the site of a cyst, accompanied by hemorrhage in the ovarian tissue and or intraperitoneal bleeding. ref http www.art med.ru articles list art238.asp ref Pathogenesis In the ovaries of sexually mature women, follicles grow, and oocyte matures in them, to prepare for potential fertilization. As a menstrual cycle progresses, a dominant follicle begins to stand out, and in the middle of the menstrual cycle it reaches its maximum size of about 20mm. Then the follicle ruptures, releasing a mature egg, and this process is called ovulation . The location from which the follicle emerges then forms a temporary cyst, called the corpus luteum, which produces hormones to continue the menstrual cycle and mature the uterine lining. This is the normal ovarian cycle . In cases of dystrophic and sclerotic changes in ovarian tissue, acute and chronic inflammatory processes in the uterus, or in polycystic ovary syndrome and some other diseases, as well as the result of medication that stimulate ovulation, certain irregularities in ovulation process and corpus luteum formation occur.
