Ovarian diseases refer to diseases or disorders of the ovary.

These can be classified as endocrine disorders or as a disorders of the reproductive system.

If the egg fails to release from the follicle in the ovary an ovarian cyst may form. Small ovarian cysts are common in healthy women. Some women have more follicles than usual (polycystic ovary syndrome), which inhibits the follicles to grow normally and this will cause cycle irregularities.

Various types of ovarian diseases exist. Some of the ovarian diseases or disorders include: endometriosis, ovarian cysts, ovarian epithelial cancer, ovarian germ cell tumors, ovarian low malignant potential tumors, and polycystic ovary syndrome (PCOS).

Endometriosis is a condition in which tissues lining the uterus (endometrial stroma and gland) grows abnormally beyond the uterus that may become quite painful. In simpler terms, it means that the tissue lining the uterus develops in different parts outside of it. It can be either at ovary, fallopian tubes, or peritoneal spaces.

There is no single cause of endometriosis.

Symptoms:

Menstrual cramps, heavy menstrual bleeding, bowel or urinary problems, nausea, vomiting, blood with stools, painful intercourse, fatigues, spotting or bleeding between periods.
