We discussed above, Endometriosis is the growth of endometrial tissue due to the location outside the uterine cavity caused lesions. Well, these endometrium is how long the site to the other? Currently there are several theories:
(1) blood reflux theory: that menstrual blood reflux into the fallopian tube through pelvic so put off the menstrual period to pelvic endometriosis, uterine rectum in Waterloo, ovarian or other parts of the cultivation, development for endometriosis .
(2) body cavity metaplasia theory: that germinal epithelial ovarian, umbilical pelvic peritoneum, pleura and so epithelial origin in the body cavity, which can stimulate inflammation or blood in the stimulation into endometrial.
(3) benign transfer theory: Some people believe that endometrial tissue can be disseminated through venous or lymphatic.
(4) direct transplantation doctrine; if surgery is in some cesarean section, abortion or childbirth process, the endometrium was taken to the wound, and the development of endometriosis.
In short, on endometriosis pathogenesis, although each has its own different theories arguments, but not perfect, it may not be that the majority of current from a channel, but to grow and endometrial cavity metaplasia of the argument mainly.
