Fallopian tubes are an important part of the female reproductive system. They connect the ovaries to the uterus. Therefore, any blockage in the fallopian tubes can upset the normal functioning of the female reproductive system. The fallopian tubes are responsible for delivering the ovarian egg (ova) to the uterus during pregnancy. Therefore blocked fallopian tubes can cause infertility. Such type of infertility is the cause of 20% infertility in women and is known ad tubal infertility.
The factors which increase the risk of having blocked fallopian tubes are as follows:
Women suffering from blocked fallopian tubes, generally do not experience symptoms except in the case of hydrosalpinx. A hydrosalpinx is a condition wherein the fallopian tubes are blocked, resulting in a collection of fluid.
Pelvic Inflammatory Disease is the major cause of tubal blocks. When bacteria causing sexually transmitted diseases spread to the pelvic area it results in PID.
Other potential causes of blocked fallopian tubes :
To ascertain tubal blocks, the doctor may recommend sonohysterosalpingography. It is a procedure similar to ultrasound but in this procedure the surgeon also inserts a saline solution into the cavity of the uterus, this helps the doctor to see things which would not be possible with normal ultrasound.
It is important to note that in 15% of the cases the results maybe false positives. Therefore the doctor may perform the test once more.
Although it is possible to conceive with one functional fallopian tube, the pregnancy rates in such cases are lower. If both the tubes are blocked then a laparoscopic surgery may be performed to free up the fallopian tube. Alternatively assisted conception techniques like IVF may be used,
