Endometriosis is related to female infertility. In the sufferers who are diagnosed with infertility, endometriosis account for 42.35% to 55.7%.

Why does endometriosis cause female infertility? There are several reasons:

1. Endometriosis can cause tubal blockage. Malposed endometrium can cause cyclic hemorrhage. Then, blood can’t circulate and cause scar. Fallopian tube is blocked and influence the transport of zygote. The adhesion can prevent sperm from getting into uterus and prevent ovum from discharging. The endometriosis cyst can also influence the ovum from ovary.

2. The combination between sperm and ovum can be influenced by the pelvic microenvironment. The patients usually have a lot of peritoneal fluid. The peritoneal fluid has prostaglandin (PG) and macrophage which can affect the normal movement of fallopian tube. So the activity of sperm is reduced and it is hard to combine with ovum.

3. The abnormal immunologic function can affect homergy and physiological function. The recent research indicates that sufferers have abnormal immunologic function. The material produced by malposed endometrium can be absorbed by macrophage. Then antibody appears and harm the function of endometrium so embryo is hard to be formed.

As a result, few cases of endometriosis can cause tubal blockage. Endometriosis often affect the function of ovary and prevent sperm from meeting the egg. The above situation can cause infertility. Endometriosis can cause female infertility but getting pregnant can be a good way to treat endometriosis, because it can control the grow of endometrium cell. What you should be attention is that you can get pregnant when you suffer endometriosis but you have a high risk of abortion. Endometriosis is the most common reason why you can’t get pregnant. Thus, you should go to see your family doctor immediately if you feel the relative symptoms.
