There are many different causes of ovarian cysts. Under the normal menstrual cycle, ovaries grow cyst-like structures called follicles each month. These follicles produce hormones necessary for pregnancy such as estrogen and progesterone. Ovarian cysts can form when a normal follicle continues to grow for an abnormal period of time.

Follicular cysts are among the most usual type. These cysts rarely have symptoms, usually harmless and disappear on their own. Ovarian cysts affecting the follicle are caused by the release of hormones from the pituitary gland that is supposed to initiate the release of an egg. Failure to release the egg makes the follicle continue to grow and develop into a cyst.

Frequent causes of ovarian cysts occur when luteinizing hormones surge and an egg is release. When the egg is released, estrogen and progesterone are created by the ruptured follicle to prepare for the hypothetical conception. When the egg is sealed off, fluid accumulates inside the follicle and becomes what is called a corpus luteum. The corpus luteum will then expand and at that point becomes a cyst.

Treatment is normally not needed for a corpus luteum cyst as it typically disappears. Before it does disappear it can grow to almost 4 inches in diameter. Hemorrhaging and twisting of the ovary can also potentially occur. Severe pelvic and abdominal pain can result. Corpus luteum cysts may rupture if filled with blood, this can cause sharp pain and internal bleeding.

It is important to note that the fertility drug clomiphene citrate, which is commonly used to induce ovulation, might be one of the causes of ovarian cysts, since it can often increase the risk of the development of a corpus luteum cyst. Corpus luteum cysts do not prevent or threaten pregnancy.

Ovarian cysts containing blood, known as hemorrhagic or endometrioid cysts, form in the same way. The presence of blood might have been the result of an injury or from leakage of surrounding blood vessels through to the egg sac. When causes of ovarian cysts from bleeding and shedding of endometrial tissue occurs in the ovaries, painful cysts may form. If left to continue, the pooling blood may rupture causing pelvic pain.

There are several ways to decrease the causes of ovarian cysts. The most important things you could do include, but are not limited to, get more exercise, decrease stress, eat healthy, and improve your overall health.
