An ovarian cyst is a fluid-filled sac (follicle) that contains a
maturing egg. It forms on the ovary's surface, then disappears not long after
it releases the egg. If a mature egg is not released or if the sac reseals
after releasing the egg, the sac can swell up with fluid, forming a
functional ovarian cyst.
Most functional ovarian cysts do not cause symptoms and go away by
themselves. But they do sometimes rupture, twist, or bleed, which can
cause severe pelvic pain.
