As we mentioned in previous articles, during the last stage of the menstrual cycle normally a layer of endometriosis lining in the inside of the uterus is expelled, known as menstruation blood but instead some of the endometriosis tissues grow somewhere in the body causing endometriosis. Endometriosis also reacts to hormonal signals of the monthly menstrual cycle, building up tissue, breaking it, and eliminating it through menstrual period. In this article, we will discuss what exhibits congenital or embryonic rest to cause endometriosis?

I. Definition
Congenital or embryonic rest is the irregular cellular development, during the the embryonic stage, a fragment of embryonic tissue that has been retained after the period of embryonic development. In case of endometriosis, Some of the endometrial cell normally growth in the womb, for whatever reason, they develop in abdominal regions.

II. Causes of congenital or Embryonic defects
1. Hormonal imbalance
During the embryonic stage, if the mother having a sudden surge of estrogen or high estrogen level for a prolong period of time cause low level of progesterone that is necessary for nourishing the fetus resulting of defection of cell development. Some of the endometrial cell may develop irregularly in the abdomen.

2. Hormonal stimulating medication
There are some women taking hormonal stimulating medication to influence the hormone system to produce certain hormones, resulting of hormonal imbalance or abnormal cellular development during pregnancy stage. Over production of estrogen may influence the irregular development of endometrial cells in the wrong place in abdomen area or miscarriage.

3. Environment factor
Synthetic chemicals such as insecticides, herbicides, gasoline fumes, food packaging is harmful to human body. If pregnant women come in contact with these types of toxins for prolong period of time, it not only causes weakening of immune system but also surging of certain types of hormones resulting of malfunction of cells development in the fetus. If such malfunction is endometriosis related than it may influence irregularly the development of endometrial cells other than in the endometrium.

4. Xenoestrogen
Unhealthy diet during pregnancy with intake of xenoestrogen promoting foods for pro long period of time, cause over production of harmful estrogen that stimulates the irregular endometrial cell development resulting of endometriosis.

5. Congenital defects
Congenital defects such as cervical stenosis, lack of open in the hymen or other congenital abnormalities causing menstrual blood retention in the uterus or retrograde menstruation that allows endometrial cells to implant in the abdominal region.
