2. Pain when ovulating
A small number of women feel pain when they are ovulating, and that is considered normal in most cases. However, pain during ovulation can be a consequence of endometriosis. Ovulation itself is the process through which the egg, once it has matured due to the effect of estrogens and follicular stimulant hormones, is released from the ovary into the Fallopian tubes, where it can be reached by a spermatozoon so fecundation takes place.
A small pinch of pain is normal when the egg is released from its follicle inside the ovary. However, some women with endometriosis have an abnormal growth of endometrial cells in one or both of their ovaries. In advanced cases, they might even develop an ovarian cyst as a result. The abnormal tissue present in an ovary can react during the release of the egg, and become irritated or even damaged, thus causing pain during ovulation.
