The Fallopian tubes are structures of the female reproductive system that connect the ovaries to the uterus. Its function consists of collecting the ovum released by the ovary, allowing meeting with the sperm and fertilization and, finally, transporting the embryo to the uterus.
Therefore, any injury or obstruction of the Fallopian tubes that prevents their function will be a cause of female sterility.
The different sections of this article have been assembled into the following table of contents.
Tubal alterations are an impediment to achieving pregnancy in 30-40% of patients with infertility problems.
As stated above, Fallopian tubes must be permeable and able to move in order to perform their function.
Sometimes a woman only has a unilateral tubal factor, i.e. one of the tubes is affected and the other is healthy. In this case, natural pregnancy is possible, although the chances are reduced by half.
When the tubal factor is bilateral, both tubes are damaged and therefore pregnancy will not be possible.
Next, we will comment on the causes of this tuboperitoneal factor.
Pelvic infection is the most frequent cause of tubal injury, accounting for 80% of cases.
The microorganisms responsible for most infections in the female reproductive system are Chlamydia Trachomatis (chlamydia) and Neisseria Gonorrhoae (gonorrhea), which are responsible for sexually transmitted diseases (STDs).
It is very important that women take care of their intimate hygiene on a daily basis and be careful with unprotected sex in order to avoid STDs.
Other causes that may produce pelvic infection include curettage after an abortion, puerperal sepsis, or insertion of a copper IUD.
If microorganism infections are not treated properly, they can affect the cells of the cervix and spread to the ovaries, fallopian tubes, or uterus, causing pelvic inflammatory disease (PID) and infertility.
Surgeries of the pelvis and its scars can cause adhesions in the abdominal tissues that limit the activity of the tubes. Some examples of surgeries that can involve complications are the following:
- Appendicitis operation
- Removal of ovarian cysts
- Removal of fibroids
- Intervention for endometriosis
- Surgery to treat uterine malformations
Pelvic adhesions are bands of scar tissue that form between the organs of the pelvis (ovaries, Fallopian tubes, uterus, bladder, and bowel) and can cause them to attach to each other and lose their function.
Endometriosis is an invasive disease in which endometrial tissue leaves the uterus and is implanted in other locations.
Therefore, endometriosis is another disorder that can cause pelvic adhesions that damage or block the Fallopian tubes.
The endometrial tissue can be inserted between the ovaries and the Fallopian tubes, making it difficult for the eggs to be received by the outermost part of the tube: the fimbrias.

Hydrosalpinx is an alteration of the Fallopian tubes characterized by the accumulation of fluid inside them. This causes the tube to dilate and become clogged.
The most common cause of hydrosalpinx is usually a previous infection.
It is very important to treat and remove hydrosalpinx before attempting pregnancy, since, in addition to causing tubal obstruction, the fluid that accumulates is toxic to embryos.
There are other problems with the Fallopian tubes that can impair their function. These are discussed below:
- Congenital malformations of the tubes
- Pathology of immobile cilia
- Ectopic pregnancy resulting in removal of the tube (salpingectomy)
- Tubal ligation
Any alteration in the Fallopian tubes that prevents their permeability and freedom of movement is a cause of tubal factor infertility.
In most cases, problems in the Fallopian tubes do not cause symptoms that a woman can perceive. Therefore, the tubal factor will only be diagnosed when the couple has not conceived for some time and proceeds to fertility tests.
Alterations in the Fallopian tubes can be detected by the following diagnostic tests:
- Hysterosalpingography (HSG)
- is the most important test to check the permeability of the tubes. It consists of injecting a contrast dye through the cervix to observe its trajectory towards the tubes as x-ray pictures are taken. If there is any obstruction, the contrast dye will become trapped and cause the tube to distention.
- Hysterosalpingosonography (HSSG)
- is an improved version of the previous HSG. Here, a saline solution or foaming gel is used to inject it through the cervix instead of the contrast dye. In addition, the use of x-rays is replaced by a routine transvaginal ultrasound. To make the HSSG, you can use the ExEm Foam Kit..
- is a surgical intervention in which two small incisions are made under the navel and a camera is introduced that allows the tubes to be observed from the abdominal cavity, as well as their relationship with the rest of the structures of the reproductive system. It is usually done in case of suspicion of endometriosis or any adhesion that can be removed at the same time.
Bacterial infections such as chlamydia should be treated with antibiotics such as azithromycin and doxycycline. However, if the Fallopian tubes are already damaged, the drugs will not be able to fix this condition.
As for the application of surgery to repair the Fallopian tubes, this will be possible depending on the cause of the tubal obstruction and its severity. Endometriosis is usually operated on with laparoscopy.
Despite this, it is quite difficult to recover fertility after tubal surgery because of its complexity. For this reason, specialists recommend assisted reproduction so that women with tubal obstruction can become mothers.
Specifically, the treatment that does not require tubal functionality to achieve pregnancy is in vitro fertilization.
In fact, as Dr. Miguel Dolz tells us:
A few years ago, the problem of tubal obstruction was the fundamental indication for undergoing IVF.
In this case, fertilization does not occur in the tube as naturally, but takes place in the laboratory. First the woman's eggs are obtained with an ovarian puncture and then they are put in contact with the male's sperm, overcoming the obstacle of the tubes. The embryos resulting from IVF can then be transferred to the mother's uterus and/or cryopreserved for future attempts.

FAQs from users
What is the best solution for getting pregnant with blocked Fallopian tubes?
IVF treatment is the most appropriate treatment to achieve pregnancy when the woman does not have tubal functionality. Usually, it is the technique of choice in women who have a tubal ligation done and wish to have a child. In addition, the advantage of IVF is that it also offers guarantees of success even if the male's semen is not of good quality.
What symptoms can a blocked Fallopian tube have?
Tubal obstruction usually has no symptoms as such. However, it is possible for a woman to have discomfort when the cause of the obstruction is related to endometriosis or infections. Some of these discomforts are the following:
- Abnormal vaginal discharge
- Pain when urinating
- Bleeding between periods
- Painful menstruation
