Lining of uterus undergoes periodic changes and gradually thickens with influence of hormones. When oocytes are not fertilized, the lining of uterus would naturally shed, together with the oocytes released, to form "menstruation".

Endometriosis is a menstrual-related gynaecological disease that refers to growth of endometrial tissue outside uterus. Endometriosis often takes place in ovaries, fallopian tubes and tissues around the uterus.

Endometriosis occurs in fallopian tubes
