Each month after ovulation a Mature egg moves through the fallopian tube from the ovary towards the uterus. Under certain circumstances, meet her moving sperm. If the meeting of gametes took place, there was a fertilization is formed the embryo, which is also to be reached through the fallopian tube to the uterus to be implanted there, and only then comes the pregnancy.

These momentous events may prevent the obstruction of the fallopian tubes.

The types and causes obstruction

Tubal obstruction may be complete or affect only one tube. It may be in the adhesive process around pipes, blockage of their channel, violation of activity of the villi or contractions of the pipe. In the latter two cases, the lumen of the tube remains free, but the movement of a fertilized egg difficult.

The main cause of obstruction of the fallopian tubes are inflammatory diseases of the female organs. The width of the lumen of the fallopian tube does not exceed 1 cm, and it is easily filled with pus or mucus. If untreated, it leads to scarring and adhesions. Especially dangerous are the hidden sexual infections is asymptomatic: Mycoplasma, chlamydia, ureaplasmosis. In these cases, the woman does not know that is sick and not treated.

No less dangerous tuberculosis, which affects not only the lungs but and other bodies, including childbearing. The occurrence of complete obstruction of the fallopian tubes and other developmental abnormalities of the female organs is most likely if the girl had contracted tuberculosis in puberty.

Other reasons, such as endometriosis, tumor of female organs. This anomaly occurs in women who have had abortions, ectopic pregnancy, surgery on the abdominal organs (e.g., Appendix).

Symptoms and diagnosis

If the obstruction of the pipes is associated with some recurrent inflammatory disease, a woman may feel pain during sexual intercourse and during menses, may occur profuse discharge of yellow color. But this is not always, very often this condition is not manifested in any way, its only a symptom of the inability to become pregnant.

Determining the cause of infertility, the doctor needs to check the presence of obstruction of the pipes. This can be done using hydrosonography into the cavity of the uterus is injected with sterile saline, and then with the help of ultrasound and watching where it flows. Under normal condition of tubes and the solution will flow through them into the abdominal cavity, with obstruction this does not happen, the uterus will expand. This method does not allow to accurately diagnose partial obstruction.

More informative hysterosalpingography – an x-ray of the uterus and tubes taken after injection into the uterus of a contrast agent.

The most effective laparoscopy. This method allows to diagnose not only the obstruction of pipes, but other possible causes infertility: polycystic ovaries, endometriosis. Some violations are eliminated already in the process of diagnosis – for example, adhesions cut.
