Tubal Block

Tubal Block

Fallopian tubes are the female reproductive organs that carry an egg from the ovaries to the uterus. They function as the connecting bridge between the ovaries and the uterus. Even the process of fertilization takes place in the tubes. Blocked fallopian tubes lead to infertility in women as they do not allow the fertilization to take place as the egg can't travel to the uterus.

Tubal blocks account for around 25% of all infertility cases. The blockage can occur in both the tubes – complete blockage, or there can be just blockage in one of the tubes - partial blockage.


Mostly tubal blocks are asymptomatic. There will be no noticeable symptoms until women consult a doctor for their infertility. In some cases, they might cause pain on one side of the abdomen.


The various reasons for which the tubes get blocked include:

  1. Endometriosis
  2. Pelvic inflammatory disease
  3. Ectopic pregnancy
  4. Fibroids
  5. Scar tissues or pelvic adhesions
  6. Sexually transmitted infections
  7. History of abdominal surgery
  8. Previous burst appendix


To confirm the blocked tubes either one of the below procedures is performed by the doctor :

  1. Hysterosalpingogram (HSG): It is a kind of x-ray wherein a dye is injected with the help of a catheter through the cervix into the uterus. The dye helps to study the tubes in detail, and if it freely flows till the end of the tubes, then they are free of blockage. If the liquid does not flow completely from both or one of the tubes, it is considered to be affected.
  2. Laparoscopy: If the results are not clear from the HSG test, then a laparoscopic procedure is advisable to study the tubes, ovaries, and the pelvis. and In a few cases, the blockage may be corrected.


The treatment offered depends on the type of blockage. If there is a partial blockage, then fertility medications are given to increase the chance of ovulation on the open tube side. If both the tubes are blocked, then laparoscopic surgery is recommended to open the blocks. Most of cases, doctors might recommend IVF instead of surgery due to the risk of ectopic pregnancy.
