Endometrial is the tissue which surrounds the inner surface of the uterus. It is responsible for the menstrual cycle in women. Thus, also acts as the major cause for infertility in women. Endometriosis is the condition in which the tissue of endometriosis moves out of the uterus and attaches to the other organs in the abdominal cavity like fallopian tube and the ovaries.

Endometriosis is considered as the major reason for infertility in women. It is a progressive disease. In this disorder some bits of tissues moves out of the uterus in the abdominal cavity. These bits of tissues of endometrial can cause pain and irregular bleeding and could also affect the ability of the women to become pregnant.

Causes Of Endometriosis:
The causes of endometriosis can be summarized in the following points:

• Retrograde Menstruation: It is the condition in which the blood instead of flowing out through the cervix and vagina it flows backwards along the fallopian tubes into the abdominal cavity. It also carries living endometrial cells also along with it.
• Immune System Defects: Endometriosis can be resulted as one of the defects of the immune system. It can be a specific defect which could eradicate stray cells migrating outside the uterus.
• Hereditary: This disease has been termed as hereditary disease.so, the genes of this disease are supposed to be in the women if it was there in her family.
• Embryonic Tissue Theory: There is a theory that endometriosis can be caused by the microscopic remnants of women’s embryonic tissue which later results as endometriosis.
• Estrogen Theory: Endometriosis is related to activity of the hormone called ‘Organochlorines’. These are man made chemicals which are contained in the pesticides. These organochlorines are capable of increasing the estrogen related conditions like ‘Endometriosis’. They are also held responsible for various cancers also.
