There are a number of factors that can cause the blockage of the fallopian tube. Such causes include any history of a severe STD infection in the past; Gonorrhea and Chlamydia in particular. In some scenarios a previous ectopic pregnancy, abortion and miscarriage may cause a uterine infection. And also a surgery gone badly on the fallopian tubes or the abdominal part might cause an infection that will lead to the blockage of the tubes.
When fluids accumulate in the tube to extreme extent it can cause infertility due to the inability of the ovum to sail to the uterus to fuse with the sperm. In the early stages of the blockage some of the symptoms are painful menstruation and painful sexual intercourse. But the symptoms might be caused by another infection, so you have to confirm your doubts. To know if you have the problem you will have to take a specialised x-ray known as a hysterosalpingogram test or even ultrasound might be used.
In case of partial blockage, fertility drugs might work as they increase the chances of fertilisation occurring on the tube that is open. In instances where both fallopian tubes are severely damaged and there is no other option. You can opt for the in-vitro fertilisation which is more effective and will solve most of the effects of the tubal problems. You have to consult a fertility speciality who will harvest your eggs and after fertilizing the eggs they place the fusion into your womb. This is the only best potential treatment for the blocked fallopian tubes. Some may opt for a surgery or even an artificial fallopian tube transplant. This is not the better option as it is not effective functionally and due to its high charges; besides, they were tried in 1974 but later rejected.
