Instead some of the endometriosis tissues grows somewhere in the body causing endometriosis. They also react to hormonal signals of the monthly menstrual cycle, building up tissue, breaking it, and eliminating it through the menstrual period. In this article, we will discuss the relationship of endometriosis and irregular menstruation
