N83: Noninflammatory disorders of ovary, fallopian tube and broad ligament

N83.2: Other and unspecified ovarian cysts

The ovaries are part of the female genitals. There are two ovaries, one on each side. The ovaries sit low down in the abdomen. Egg cells mature in the ovaries. The egg cells can later develop into a child. The ovaries also produce various messenger substances.

Fluid-filled sacs (cysts) can occur at various places in the ovary. They sometimes appear during pregnancy and sometimes with no clear cause.

In most cases these cysts do not cause any problems and clear up without treatment after a while. If the cysts become very large, you may have abdominal pains, for example. The cysts may also affect your periods.
